Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional lighting arrangements with fluorescent tubes are used, then illumination is provided, but the system lacks scalability and modularity for adjusting size
Solution Approach 1:
The lighting system is divided into multiple identical light modules, each containing an LED and optical element. These modular units can be independently arranged and combined to create lighting arrangements of various sizes, enabling scalability while maintaining a simple standardized structure for each module.
Solution Approach 2:
Each light module is designed as a universal unit that can be used in different positions and configurations within the lighting system. The standardized interface and identical functional design allow the same module to serve multiple purposes across different system sizes, enhancing versatility without increasing structural complexity.
2Ease of operation
If light modules are made easily replaceable without tools, then maintenance is simplified, but secure attachment may be compromised
Solution Approach 1:
The fastening system uses elastic fastening arms that can dynamically adapt during assembly. The arms are flexible enough to be manually pressed together for easy installation without tools, yet they exert sufficient elastic force to securely hold the light modules in place during operation, balancing ease of replacement with reliable attachment.
3Illumination intensity
If multiple light modules are used to achieve complete illumination, then coverage is improved, but assembly complexity increases
Solution Approach 1:
The illumination task is segmented across multiple identical light modules, each responsible for illuminating a specific portion of the light disk. This segmentation allows complete coverage to be achieved through simple repetition of standardized units rather than through a complex integrated design, maintaining assembly simplicity while improving illumination coverage.
