Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual lens exchange is used to change output angle, then different emergency lighting applications can be achieved, but the process is laborious and time-consuming
Solution Approach 1:
The patent implements a motorized lens mechanism that enables dynamic adjustment of the output angle without manual intervention. The lens can be rotated electrically to change the light distribution pattern, transforming a static manual exchange system into a dynamic automated system that adapts to different emergency lighting applications instantly.
Solution Approach 2:
The patent replaces the manual mechanical lens exchange process with an electrical motor-driven system. Instead of using screwdrivers and manual handling to exchange lenses, an electric motor rotates the lens to different angular positions, substituting mechanical manual operation with automated electromechanical control.
2Adaptability or versatility
If manual lens exchange is used to change output angle, then different light distributions can be achieved, but the effort required is high
Solution Approach 1:
The system performs self-service by automatically adjusting the lens angle through motorized control. The emergency lighting unit autonomously changes its light distribution pattern without requiring human intervention, effort, or manual lens handling, thereby eliminating the laborious exchange process while maintaining adaptability to different applications.
Solution Approach 2:
The patent introduces a motorized mechanism as an intermediary between the control system and the lens. This intermediary component translates electrical commands into mechanical lens rotation, mediating the adjustment process and eliminating the need for direct manual handling of the lens by the user.
3Adaptability or versatility
If multiple lenses with different output angles are provided, then different emergency lighting applications can be covered, but the device complexity increases
Solution Approach 1:
The patent implements a universal optics module where a single lens can perform multiple functions by being rotated to different angular positions. Instead of requiring multiple separate lenses for different emergency lighting applications (anti-panic, escape route, spot lighting), one lens serves all purposes through motorized angular adjustment, thereby reducing device complexity while maintaining full versatility.
