Refine and develop procedures to finalise a design proposal, recognising the constraints of time, cost and resources, and plan for making
Candidates refine and develop the design proposal considering the time, cost and resources used to produce the product. Candidates produce accurate working drawings for the final design solution.
Candidates produce a plan for making an individual (one-off) product showing all the stages in the correct order to make the product.
A final Design sketch to make it clear what you are trying to manufacture
Any final test models and material testing before commencing Final CAD modelling
Model your final design proposal in Onshape and then produce accurate, detailed working drawings (including annotations).
Produce a Cutting list / BOM drawing to show the number of parts, size and shape of each individual part
Produce Exploded Drawings to show how the parts fit together and the construction of the individual components.
Include Virtual Renderings of the completed design to show through the application of materials, the sleceted materials to be used and the components required. At this point you can also show the Finish that this required for each part.
Flow Chart (planning) for an idividual one off product
Gantt Chart (or other scheduling software)
Evidence to be submitted
The candidate’s portfolio must provide the following evidence:
(a) Refine and develop procedures to finalise the design proposal
• record the procedures used to fully develop the design proposal produced in Stage 2
• recognise the following constraints in the design proposal with detail on how they have been considered:
– time
– cost
– resources (materials, tools, equipment and components)
Candidates can use photographs of physical models or screenshots of computer modelling to record the procedures used to develop the design proposal.
(b) Produce working drawings, to a suitable scale and with annotations, for the final design solution
• accurate working drawings, CAD or hand-drawn that show:
– the number, size and shape of individual parts
– how the parts fit together
– the materials and components required
– the finish
• appropriate drawing methods for working drawings include:
– orthographic views
– exploded views
– isometric or perspective drawings
The working drawings can be accurately hand-drawn and/or can be screenshots from drawings produced using CAD software programs.
(c) Produce cutting lists
• list of materials required to make the product
(d) Plan to make the final design solution
• a plan for making an individual (one-off) product of the final design solution, that shows:
– the stages in making
– the correct sequence of making
– the time required for each stage in the making
– the materials, tools and equipment required for each stage in the making
– safety considerations for each stage in the making
• use of appropriate planning and scheduling tools such as:
– flowcharts
– Gantt charts
The working drawings and planning and scheduling tools should contain sufficient detail to allow a skilled third party to make an individual (one-off) version of the final design solution.
Gather opinions on colour, texture, and finish.
Example
Product Name: EcoCharge Portable Solar Charger Prepared For: 'GreenTech Innovations' Executive Board. Date:October 14, 2025 Version: 1.0 - Final Design Approval
This slide presents the final design proposal for the "EcoCharge Portable Solar Charger," a compact, durable, and highly efficient device aimed at providing reliable off-grid power for mobile devices.
