Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If LED modules and control circuits are integrated in a compact lighting apparatus, then space utilization is improved, but signal interference increases
Solution Approach 1:
The control circuit is divided into two separate locations: the sensor is placed inside the concave container away from LED modules, while the control circuit board is mounted on the outer surface of the base plate. This spatial segmentation isolates the control circuit from LED modules, reducing electromagnetic interference while maintaining compact integration.
Solution Approach 2:
A through-hole is provided in the base plate to establish electrical connection between the sensor (inside the container) and the control circuit board (on the outer surface). This intermediary structure enables signal transmission while maintaining physical separation between components, thus reducing interference.
2Volume of moving object
If multiple LED modules are arranged in a compact space, then device size is reduced, but light quality and flexibility deteriorate
Solution Approach 1:
The lighting apparatus utilizes a three-dimensional concave container structure where LED modules are arranged vertically along the inner wall. This vertical arrangement in the depth dimension allows multiple LED modules to be integrated without increasing the horizontal footprint, maintaining compact size while preserving light quality through proper spatial distribution.
Solution Approach 2:
Different LED modules can be positioned at different locations within the concave container to create varied lighting effects. The control circuit can independently adjust parameters for different LED modules, enabling local quality adjustment of light output while maintaining overall compact design.
3Device complexity
If control components are placed close to LED modules, then integration is improved, but signal interference increases
Solution Approach 1:
The control system is segmented into sensor and control circuit board, placed in different locations. The sensor is integrated inside the concave container close to LED modules for accurate sensing, while the control circuit board is positioned on the outer surface away from LED modules to minimize interference. This segmentation maintains functional integration while reducing harmful electromagnetic effects.
4Use of energy by moving object
If traditional lighting sources are replaced with LEDs, then energy efficiency is improved, but initial cost increases
Solution Approach 1:
The base plate serves multiple functions: it provides structural support, acts as a mounting surface for LED modules and control circuit board, and functions as a heat dissipation component. This multi-functionality reduces the need for additional components, lowering manufacturing complexity and initial cost while maintaining LED energy efficiency advantages.
