Design and creation - invention of a manual spray for indoor plants

Résumé du document

The target of design and manufacture is to explain the steps that we have to do when we want to make a product. This starts from the marketing research to the molding process. In order to illustrate this, we were supposed to create a manual spray for an indoor plant. In this report, I will describe in detail every step that led me to my final spray. First of all, we need to position the product in the market. Hence, the first step is to do market research. Today, the fact is that more and more people buy indoor plants every year. For instance in 2008, in every second, about six indoor plants were sold in France. The Product Design Specification is the outline to create the spray and to achieve it we need to use tools to respect all these specifications and be creative. A tool like The "TRIZ" helps Engineers to find innovative concept and direct them to resolve problems. We analyze the different steps involved in this process in this document.

[...] Finally this is a great opportunity to launch a spray on the market. However the spray market is old and a lot of sprays are already introduced. To find a position we have to establish Product Design Specification” which is the second Step. The Product Design Specification is the outline to create the spray, nevertheless to achieve it we need to use tools to respect all these specifications and be creative. A tool like The helps Engineers to find innovative concept and direct them to resolve problems. [...]

[...] This year to illustrate this we were supposed to create a manual spray for indoor plant. In this report I will retake every step that led me to my final spray. First of all to create a product we have to find a positioning to introduce our product to the market. Hence the first Step is to do market research. Today the fact is that more and more people buy indoor plants every year. For instance in 2008 every second 6 indoor plants were sold only in France ( 194.4 millions plants!!!). [...]

[...] For this estimation, I used the course on tool costing (Mr. Green). First, I determined the clamping force and the shot capacity: Q1 = [2/3S]/Wp where Wp is the weight of one part (grammes) S = maximum shot capacity of machine (limited to 2/3 capacity) Q2 = C / [75 x Ap] where Ap is the projected area, along parting line, of one part (mm2) C = maximum clamping capacity of the machine I found an average injection pressure for PET of 75N/mm² on the Mitsubishi website.
