Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If students build circuits with jumper wires and loose components, then hands-on learning is enabled, but excessive time is spent building circuits and clutter is created
Solution Approach 1:
The circuit board is pre-wired with all necessary connections and components permanently mounted before use. This preliminary preparation eliminates the need for students to spend time building circuits from scratch with jumper wires and loose components, while still allowing hands-on learning through circuit selection and measurement activities.
Solution Approach 2:
The rotary selection device acts as an intermediary mechanism that allows students to easily switch between different pre-configured circuits without physically reconfiguring wires or components. This mediator enables hands-on exploration of multiple circuit types while eliminating the time-consuming assembly process.
2Adaptability or versatility
If jumper wires and loose components are used to build circuits, then circuit construction flexibility is achieved, but confusion and frustration increase among students
Solution Approach 1:
The circuit board is divided into multiple separate, clearly defined circuit areas (series circuits, parallel circuits, series-parallel circuits), each with its own designated components and connections. This segmentation provides construction flexibility for studying different circuit types while eliminating student confusion through organized, non-overlapping circuit zones.
3Adaptability or versatility
If multiple circuits are provided for study, then comprehensive learning is enabled, but device complexity increases
Solution Approach 1:
A single circuit board integrates multiple different circuit configurations (series, parallel, series-parallel) into one universal device. The rotary selection device provides multi-functionality by enabling access to all circuit types through one interface, eliminating the need for separate apparatus for each circuit type while maintaining comprehensive learning capabilities.
4Ease of manufacture
If traditional circuit building methods are used, then component assembly skills are developed, but component loss and storage issues occur
Solution Approach 1:
All circuit components are permanently merged with the circuit board through soldering and permanent mounting. This combining eliminates component loss by securing all parts in fixed positions, while storage issues are resolved since the entire circuit assembly remains integrated on the board rather than requiring separate storage of individual components.
