These boxes are usually made of wood or metal, or of corrugated fiberboard, or other non durable material. Most of the people like to get food at their door steps whether it was their residing place or their working spot. Mainly some restaurants carry out deliveries within the range of some kilometers so that they can easily provide from their location. This home delivery service can assist us a lot while we are enjoying a relaxed evening. Mostly the meals ordered for immediate use can be fresh and can take in immediately. There are many types of delivery boxes widely used by vendors for transportation of food items, such as pizza, cake burger etc. And also for delivery of postal and courier letters and packets. Pizza delivery box is a service normally made with a scooter, automobile or bicycle.

Advance Design Project Report 10 QFD (Quality Functional Deployment): Quality functional deployment is a design planning process driven by the customer requirements. QFD deploys the “voice of the customer” throughout the organization. QFD uses planning matrices each called “house of quality”. The goal of QFD is to translate often subjective quality criteria into objective ones that can be quantified and measured and which can then be used to design and manufacture the product. The 3 main goals in implementing QFD are: 1. Prioritize spoken and unspoken customer wants and needs. 2. Translate these needs into technical characteristics and specifications. 3. Build and deliver a quality product or service by focusing everybody toward customer Satisfaction. QFD uses four phases:
Product planning Product design Process planning Process control
QFD in our project aims at the following three types of customer requirements: 1. Revealed requirements: These are the requirements which we get by just asking the customer what they want. These requirements satisfy in proportion to their presence in product or service. For e.g. in our project of food delivery box, hot delivery of food is the revealed requirement. The hotter the delivered food, the more they like it. 2. Expected requirements: these requirements are very basic that sometimes they may fail to mention them until we fail to perform them. They are the basic expectations without which the product or service may cease to be of value; their absence is very dissatisfying. For example in our project if the food which is to be delivered is served hot, customer barely notice it. If it’s cold, dissatisfaction occurs. There are some other expected requirements in our QFD, which are as following: Size Durability
Advance Design Project Report
Locking system Aesthetic look Portable Keep the food static Keep the food hygienic Dimensional stability
3. Exciting requirements: these requirements are the additional features put up by the organization into their product to excite the customer. These requirements are difficult to find. These are beyond the customer expectations. Their absence doesn’t dissatisfy but their presence excites. These are the things that wow thw customers and bring them back. In our project of delivery box these requirements are: Use of solar panel in the box Press fit locking system Waterproof Good flexibility Corrosion resistant Smooth surface Number of compartments in the box
After making the customer needs we started the customer importance rating process. It was done by taking the rating of different people and then in the final chart we take the average of all the ratings. Now after completing the customer importance matrix we started for planning matrix. In planning matrix. In planning matrix all the four students of our group have different ratings of following points: 1. Our project rating: This rating was taken as an average of the three students rating of our group. This reading was taken relatively to group B project readings. These ratings are shown in the chart 4. 2. Other’s project rating: this rating had also been taken in the same way as the above discussed rating. 3. Planned rating: It is the rating that our whole group wants to achieve for the successful completion of the project. Every individual in a group has different value of ratings on the basis of the customer needs. All the ratings are between 1-5, where
11
Advance Design Project Report 1 indicates the weak point 3 indicates the medium point 5 indicates the strong point Technical descriptions matrix: These include the certain points which tell us how different requirements of customer can be achieved. And there is an interrelationship matrix in the middle of house of quality diagram which tells the relationship between customer requirements and the technical requirements. We have used certain signs with number for depicting the relationship between the two; it has been shown in the QFD charts 1, 2, 3 and 4. Then there is correlation matrix on the top of house of quality diagram of car driver seat. It gives the interrelationship between the technical descriptions/requirements. In our house of quality for a car seat we have used the following methodology:
For a strong relationship we used (+) sign. For trade off we have used negative sign (-).
FAST: Functional Analysis System Technique It is a functional analysis method that helps to describe and to interpret complex system. It starts by a principal function that will be decomposed to component function that can be also decomposed to elementary functions. The analysis goes from more general (MG) to more detailed (MD). It adapts an interrogative approach:
From MG to MD: it helps to find the way to construct the solution. (HOW)? From MD to MG: it helps to justify the choice used to construct the solution. (WHY)?
Graphical construction The method has a graphical representation. To represent a function we use a rectangle containing a verb describing the function. The flow of information is an arrow, it can be: Input arrow to describe data or constraint
Output arrow to give results of the function (data or constraint for another eventual function).
Implementation of FAST in delivery box design:
12
Advance Design Project Report In our fast diagram four students made a survey regarding how to keep the food which is to be delivered hot and hygienic. Every student had different points regarding the maintenance of hotness in the delivery box to keep the food hot. The criterion of how the comfortability can be achieved was: Every student made a survey in the market and visited to the various delivery box manufactures. Then we discussed together how the hotness in the box can be maintained and how to keep the food fresh and hygienic and then every student made a FAST diagram on the basis of the inputs taken from the dealers and the technicians.
DFMA (Design for Manufacturing and Assembly) Design for manufacturing is design based on minimizing the cost of production and/or time to market for a product and also maintaining an appropriate level of quality. A primary strategy in DFMA involves minimizing the number of parts in a product. It reduces part count and thereby reducing cost. It increases reliability, because if the production process is simplified, than there is less opportunity for errors. It generally increases the quality of a product foe the same reason as why it increases the reliability. In DFMA we modularize multiple parts into single sub-assemblies. Design parts in such a way that they don’t tangle and stick to each other. In our project of food delivery box we can do the following to minimize the cost and to reduce the number of parts. 1. We can use the press fit locking system instead of using the lock and key model. 2. We can use the thermocol or some insulation sheet like aluminum sheet which can keep the food hot and store the heat energy instead of using those of solar panels because use of solar panels increases the cost. 3. We can use the fiber reinforced material because it is corrosion resistant and hence increases the durability. 4. We can cover the box in a bag having stripes so that we can hang it over our back instead of using that metal frame to fit them over the bikes to handle the box.

Design specifications According to British Standard 7373 are written below. (Source: Coventry University, School Of Engineering, BRET HUGHES) Link:http://web1.eng.coventry.ac.uk/Mblake/Product%20Design%20Specification/Student%20 PDS's/PDS5.htm
Advance Design Project Report 15 Supplier to user information: 1. Storage information: Do not put water or any other type of fluid or jelly material. Keep away knives or sharp objects. Do not keep the food inside the box for more than 6 hours. 2. Service facilities: 2.1.
Maintenance and Care details:
Keep the inner side of box to make it hygienic. We can use the waterproof sheet over the box when it is raining.
3. Safety Instructions:
Avoid overuse of press fit lock. Keep the insulation sheet clean. Hold the box carefully while delivery of any item. Do not ride the bike rashly while delivering any food item.
4. Technical data and features:
Good corrosion resistance. Waterproof. Good storage capacity. Keep the food hot for minimum of 5 hours. Good dimensional stability. Good flexibility. Press fit locking system
After Sale Service If the product becomes defective due to faulty materials and workmanship, within 24 months from the date of purchase, the manufacturer will guarantee to either replace the unit free of charge provided that:
The product is returned to the manufacturer or their authorized repairers with the date of purchase
The product has not been subjected to misuse or neglect
Advance Design Project Report
The product has not sustained any damage through foreign objects, substances or accidents
Repairs have not been attempted by anyone other than the manufacturer’s service staff or authorized repair distributors.
Improvements: 1. We have changed the shape of delivery box and now it is cubical in shape. 2. Its older and new cad drawings are shown below along with the dimensions:
3. In newer version we have introduced an insulation sheet which can keep the food hot for min. 4 hours. 4. Also there is an adjustable support to adjust and place the order at one position and moreover to make the product static so that it may not get disturbed even on the rough road conditions.
Cost Estimation Process: The process of breaking mixed costs into fixed and variable portions allow us to use the costs to predict and plan for the future since we have a good insight on how these costs behave at various activity levels. We often call the process of separating mixed costs into fixed and variable components, cost estimation. The four methods of cost estimation to be discussed are listed below.
Account analysis Scatter graphs High-low method Linear regression
16
Advance Design Project Report A key input and tool/technique for the Cost Estimating process is the cost of human resources and material and equipment. With specific reference to HR costs (rates), not only are HR rates required for cost estimating but actual work performed by human resources need to be captured in order for performance reporting to be provided and to determine the actual project cost. The cost of box that we have purchased is Rs. 2100. The cost of this delivery box depends on the following: 1. 2. 3. 4. 5.
Features Man power Manufacturing process HR rates Material and equipment cost
So on the basis of above points the box that we have purchased is a simple one. It has press fit locking system. Material used is fiber reinforced plastic. And now the improving the design features in the same box are: 1. Insulation sheet to keep the food hot. 2. Waterproof bag 3. Adjustable support inside the box to hold the order or product perfectly so that it cannot move. So according to the new additional features the cost must increase. The new cost estimation is as follow:
Insulation sheet price: Rs. 600 Waterproof cover price: Rs. 400 Adjustable support arrangement in the box to keep the food static: Rs. 200 Labour cost: Rs. 1000 Total cost: earlier cost + above cost T C= 2100+600+400+200+1000 = Rs. 4300 only.
