Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If patch cords with phono plugs are used to connect multiple effects pedals and musical instruments, then sound signals can be transmitted between devices, but the cords become tangled and assembly/disassembly becomes time-consuming and cumbersome
Solution Approach 1:
The base is divided into multiple sets of magnetic members, with each set corresponding to a specific effects pedal location. Each set contains segmented magnetic members for different functions (power, sound input, sound output), allowing individual pedals to be connected or disconnected independently without affecting other connections.
Solution Approach 2:
Multiple functions (power transmission, sound input, sound output) are merged into a single magnetic connection interface. When an effects pedal is placed on the base, one magnetic connection simultaneously establishes all necessary electrical connections for power and audio signals, eliminating the need for multiple separate patch cords.
2Ease of operation
If multiple patch cords are used to connect effects pedals, then power and sound signals can be transmitted, but the cords create clutter and burden on the user
Solution Approach 1:
Multiple separate connection functions (power cable, audio input cable, audio output cable) are merged into a single magnetic connection interface. This consolidation eliminates the visual clutter of multiple cords while the internal wiring within the base manages the complexity of connecting multiple functions through one interface.
Solution Approach 2:
The base acts as an intermediary device that consolidates all connection points. Instead of directly connecting pedals to each other and to power sources with multiple patch cords, the base serves as a central hub that manages all connections, simplifying the user interface while handling the complexity internally.
