Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple players are integrated into a single system, then functionality and versatility are improved, but device complexity and connection chaos increase
Solution Approach 1:
The cabinet is divided into distinct spatial zones (front portion, rear portion, top portion, side portion) where different players and PCBs are positioned. This segmentation allows each component to have its own dedicated space, reducing connection chaos while maintaining integrated functionality.
Solution Approach 2:
Two PCBs serve as intermediary components between different players. The first PCB (with ADC) and second PCB (with DAC) act as mediation layers that organize signal flow and connections, reducing direct connection complexity between multiple players while maintaining system functionality.
2Volume of moving object
If multiple electrical accessories are integrated closely, then space utilization is improved, but heat dissipation performance deteriorates
Solution Approach 1:
The cabinet interior is segmented into different zones with varying thermal characteristics. Heat-generating components like PCBs are positioned in rear and bottom portions where heat can dissipate, while players are positioned in front and top portions, creating thermal zones that improve overall heat dissipation while maintaining compact integration.
Solution Approach 2:
Components are positioned in three-dimensional space utilizing vertical and depth dimensions. PCBs are placed in rear and bottom portions while players occupy front and top portions, creating vertical and depth-based thermal separation that improves heat dissipation without increasing horizontal footprint.
3Volume of moving object
If players are positioned close together for compact integration, then device size is reduced, but electrical wire interference increases
Solution Approach 1:
The cabinet is segmented into spatial zones that guide wire routing. Front portion players connect to front PCB, rear PCB connects to rear outputs, creating organized connection paths that minimize wire interference while maintaining compact device size.
Solution Approach 2:
The PCBs serve as intermediary connection points that organize and route electrical wires between players and outputs. This mediation reduces wire interference by creating structured connection paths rather than direct point-to-point connections between all components.
