Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional tail cap switches are used for torch control, then the structure is simple, but the multi-gear dimming control function is lacking and operation becomes complex
Solution Approach 1:
The patent merges the control circuit into the tail cap assembly, integrating the microcomputer control system, multi-gear regulating button, and electrical connections within a single compact unit. This consolidation provides sophisticated multi-gear dimming control functionality while maintaining a simple overall torch structure and user interface.
2Adaptability or versatility
If multiple separate switches are used for grouped multi-mode dimming control, then the dimming function is achieved, but the operation convenience is reduced
Solution Approach 1:
The microcomputer control system in the tail cap provides universal control capability for multiple dimming modes and gear selections through a single integrated interface. The system can handle various lighting scenarios (single gear, grouped gears, multiple modes) through one control mechanism, eliminating the need for multiple separate switches and significantly improving operational convenience.
3Adaptability or versatility
If a microcomputer control system is integrated in the tail cap with only two electric connection points, then the control functionality is enhanced, but the connection complexity is reduced
Solution Approach 1:
The patent extracts and integrates the entire control circuit including the microcomputer system into the tail cap assembly, which then connects to the main torch body through only two electrical connection points. This extraction of the control function to a self-contained module provides enhanced functionality while dramatically simplifying the connection structure between components.
