Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple adhesive signs are used, then the device complexity is reduced, but the illumination intensity and visibility to motorists deteriorates
Solution Approach 1:
The patent combines multiple functions into a single integrated sign assembly: adhesive attachment mechanism, LED illumination system, solar power generation, and motion sensing are merged into one device. This resolves the contradiction by achieving high visibility through integrated illumination while maintaining relatively simple overall structure through functional consolidation.
Solution Approach 2:
The sign assembly performs multiple functions simultaneously: it attaches to windows via adhesive, illuminates the message through LEDs, charges itself via solar panels, and activates based on motion detection. This multi-functionality allows the device to achieve high illumination intensity without requiring complex separate systems for each function.
2Adaptability or versatility
If remote control with illumination mode changes is added, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The sign assembly includes motion sensors that automatically detect approaching vehicles and trigger illumination without requiring manual remote control operation. This self-service capability provides adaptability to different situations while avoiding the complexity of manual control systems.
Solution Approach 2:
The motion sensors provide feedback about the environment (approaching vehicles) to the control system, which automatically adjusts illumination states. This feedback mechanism enables adaptability while simplifying the control interface by eliminating the need for constant remote control manipulation.
3Duration of action of moving object
If solar panels and multiple power options are incorporated, then the duration of action improves, but the device complexity increases
Solution Approach 1:
The patent merges solar power generation, battery storage, and multiple charging interfaces into a single integrated power system. This allows the device to achieve extended operational duration through combined energy sources while maintaining relatively simple structure through functional integration.
Solution Approach 2:
The power system provides multiple functions: solar energy harvesting, battery charging, and support for various charging cables (USB-C, Lightning, Micro USB). This multi-functionality ensures long operational duration while avoiding the complexity of separate dedicated systems for each power source.
4Productivity
If motion sensors and brake activation are added, then the productivity of communication improves, but the device complexity increases
Solution Approach 1:
The motion sensors and brake activation systems automatically detect when communication with approaching vehicles is needed and trigger illumination without requiring manual intervention. This self-service approach improves message delivery effectiveness while avoiding the complexity of manual activation systems.
Solution Approach 2:
The sensing systems provide feedback about approaching vehicles and brake events to the control system, which automatically activates illumination. This feedback mechanism enhances communication productivity by ensuring the message is displayed at the right moment while keeping the control system relatively simple through automatic decision-making.
