F3 - Design Process (Electronics)

Sequential Plan

A time-table of the expacted way you will move from solution to product. The plan should take into consideration the workshop time available as well as provide alternative routes should external factors come into account beyond your control.

time plan

Working Drawing

Detailed drawings that should be used in the manufacturing of the product. The number of drawings depends on the complexity of the product. Normally, one orthographic drawing followed by some isometric drawings of specific aspects of the design should be included. In the case of electronics, these drawings would relate to the bodyof the circuit casing. The final circuit drawing used to produce the product should be put here in terms of the electronics aspect, together with simulation drawings of circuit.

Making

The making process described through a step by step approach accompanied by photos of the different steps in the making process.

Testing

Testing should be made on the product & the results as well as processes should be described & recorded through wording & photos. In the testing section, modifications may be included & the models with the modifications made can be retested. If the modification is too complex, or provides other factors which makes it difficult for the manufacturer to make in the time frame alloted, the need for the modification may be mentioned but not produced.

Evaluation

All aspects of the design should be subject to an evaluation. This will include the use of valued judgement & evaluation. This is part of the itirative aspect of the design process & can thus be included in simple annotations even in parts such as the sketches. However, the main chunk of the evaluation must be made in this section & must take into consideration the final design & the modifications included.

Main topic

Chosen Idea

A thoughoraly developed idea which is explained througha set of drawings which explain all aspects of the item involved, including things such as coulour, texture, joining techniques, dimensions of each piece involved as well as the techniques & processes involved in creating the final product's casing. The chosen circuit should also be portrade here.

Subtopic

Generation of Ideas

A range of ideas, drawn as quick sketches, showing different solutions to the situation. Each sketch or drawing must be hand drawn & must include annotations, dimensions & colour. In the case of electronics, these ideas would relate to the body of the circuit casing. The electronics aspect should be represented in terms of different circuit drawings.

eg. of a display case drawing with propper annotations

eg. of a splay case drawing with visual annotations (wood texture)

Research

The research should include information which you needed to look up to be able to complete the various aspects of your project. The information you write should be in your own wording & should only include the important/relevant information.

Chris: An alarm siren can be made using an astable circuit using the NE555 IC.....

Jimmy: PVC is a strong material which can be also transparent....

Specifications

A list of factors that that provide a guide with regards to the aesthetics & functionality of a product.

Yoman: 1. Can be turned on/off safely, 2. Pressure, vibration & tilt sensitive.

Simon: 1. Independant alarm system, 2. Attaches strongly to the floor or a heady base, 3. Attracts a lot of attention.

Karl: 1. Must be highly visible, 2. Strong casing, 3. Effective alarm system

Brief

Two to three sentences that gives a guide to the direction of your work.

Fabian: Design & make a transparent PVC coloumn, that can display a valuable vase safely, can be strongly attached to the floor & conceals an alarm system. The alarm it's self must be sensitive to tilting & vibrations. The alarm must attract attention easily when it is triggered through sound & light & can be activated and deactivated via a hidden magnetic switch.

Mauro: Design & make a transparent structure, which visually exposes a vase from as many angles as possible, whilst being extremely secure. The structure must have a concaled alarm, which is very safe, attracts attention easily one triggered & is difficult to tamper.

James: Design & Make a transparent cube, that will be strong, has a secure access hole to its inside, has a pressure sensitive holder for the vase & can be firmly connected to a heavy base. The alarm must be loud & activated via a key switch.

Situation

The problem or need which your product will be aimed to solve. The situation will be normally given to you as a designer & manufacturer.

eg. The Heritage Malta Museum of Archeology in Valletta has just included a pricless vase to their collection. Heritage Malta wishes to leave this vase on display, but due to it's rarity & value, they wish that the vase is protected well using a physical encasing as well as an alarm system which do not interfier with the visual aspect of the vase.
