Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wired communication is used between modules, then electrical connection is established, but wiring complexity increases
Solution Approach 1:
The patent replaces the mechanical wired communication system with a wireless communication system. Each module is equipped with a wireless communication device that enables data exchange without physical signal wires, thereby eliminating wiring complexity while maintaining communication reliability between the base module and signaling modules.
2Adaptability or versatility
If modular design is implemented, then functionality is enhanced, but communication functionality is restricted
Solution Approach 1:
The patent implements universal wireless communication capability across all modules. The base module and signaling modules all possess wireless communication functionality, enabling them to communicate with each other and with external devices independently. This multi-functional design enhances modularity while expanding communication capabilities rather than restricting them.
3Ease of manufacture
If wireless communication is implemented between modules, then signal wires are eliminated, but communication protocol complexity increases
Solution Approach 1:
The patent segments the communication functionality into standardized wireless communication devices integrated in each module. By dividing the communication task into independent, standardized components with predefined protocols, the system achieves ease of assembly through modular integration while managing protocol complexity through standardization at the component level.
