Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a predetermined lighting device is designed for specific vehicles, then the device can be properly installed in dedicated vehicles, but the device cannot be adapted to other vehicles and requires complete replacement when LEDs fail
Solution Approach 1:
The lighting device is divided into multiple independent unit lighting modules that can be separately installed, removed, and replaced. Each module contains its own LED array and can function independently, allowing selective replacement of only faulty modules rather than the entire lighting device.
Solution Approach 2:
The unit lighting modules are designed with standardized connection interfaces (connection rail members with connection pin members) that can be universally applied across different vehicle types and lighting configurations, enabling the same module design to serve multiple vehicle models and lighting patterns.
2Reliability
If the entire lighting device is replaced when LEDs break down, then all lighting functions are restored, but resources are wasted by replacing working LEDs and the replacement process is time-consuming
Solution Approach 1:
The lighting device is segmented into replaceable unit modules, allowing only the specific module containing faulty LEDs to be replaced while retaining functional modules. This selective replacement eliminates the resource waste associated with replacing entire lighting devices when only a portion is defective.
Solution Approach 2:
Functional unit lighting modules are recovered and retained for future use, while only the defective module is discarded. The standardized connection interfaces enable easy removal of faulty modules and installation of replacement modules, facilitating resource recovery and reducing waste.
3Ease of manufacture
If a fixed lighting pattern is used, then the lighting device is simple to manufacture, but the lighting appearance becomes monotonous and lacks versatility
Solution Approach 1:
The lighting system is segmented into multiple unit modules, each capable of independent lighting operation. Different combinations of modules can create various lighting patterns and configurations, enabling diverse lighting effects while maintaining simple individual module designs that are easy to manufacture.
Solution Approach 2:
The lighting system allows dynamic reconfiguration by arranging unit modules in different patterns and combinations. The same set of modules can be arranged to create various lighting patterns (e.g., sequential lighting, simultaneous lighting, different orientations), providing versatility without complicating the manufacturing of individual modules.
4Ease of operation
If unit lighting modules are assembled with excellent assembly capabilities, then installation and maintenance become efficient, but the connection structure becomes more complex
Solution Approach 1:
The connection between unit lighting modules replaces complex mechanical fastening systems with a simplified electrical connection mechanism using connection rail members and connection pin members. This substitution enables quick plug-and-play assembly and disassembly without requiring complex mechanical tools or procedures, significantly improving installation and maintenance efficiency.
Solution Approach 2:
The connection rail member and connection pin member form a universal connection interface that simultaneously provides both electrical connection and mechanical positioning functions. This multi-functional connection structure simplifies the overall assembly process by eliminating the need for separate electrical connectors and mechanical fasteners, reducing operational complexity despite the modular design.
