Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing LED conversion kits are tailored to specific light fixture designs, then the lighting system can be adapted to specific luminaire geometries, but the device complexity and cost increase significantly requiring different retrofit kits for each light type
Solution Approach 1:
The patent implements a universal mounting plate design that can accommodate multiple luminaire types through standardized mounting patterns. The mounting plate features multiple hole configurations that can be selectively used to match different existing light fixture geometries, allowing a single LED module design to serve multiple applications without requiring custom retrofit kits for each luminaire type.
Solution Approach 2:
The retrofittable luminaire is divided into separable components: a standardized LED module assembly and a mounting plate with various mounting patterns. This segmentation allows the LED module to remain uniform while the mounting plate adapts to different luminaire types through selective use of mounting holes, reducing the need for multiple complete retrofit kit designs.
2Ease of operation
If LED modules are fixed in specific orientations based on mechanical mounting points, then the installation is simplified, but the ability to reorient light emission direction is lost requiring rotation of the entire luminaire head
Solution Approach 1:
The mounting plate incorporates rotatable mounting mechanisms that allow the LED module assembly to be oriented in different directions while remaining securely mounted. The elongated mounting holes and selectable hole combinations enable the LED module to be installed at various angles and orientations, providing flexibility in light emission direction without requiring rotation of the entire luminaire head.
3Reliability
If existing light fixtures require complete dismantling to meet IP64 protection standards, then the protection level is ensured, but the installation time and complexity increase
Solution Approach 1:
The LED module assembly and mounting plate are pre-assembled as a complete unit with integrated sealing and protection features designed to meet IP64 standards. This pre-assembly ensures that the protection level is built-in before installation, eliminating the need for complete dismantling of existing fixtures and complex on-site sealing work, thereby reducing installation time while maintaining reliability.
4Reliability
If specialized personnel are required for installation of LED conversion kits, then the installation quality is ensured, but the labor cost and complexity increase
Solution Approach 1:
The mounting plate design incorporates clear mounting patterns and standardized hole configurations that enable authorized personnel to perform the installation themselves without requiring specialized technicians. The self-contained assembly with integrated electrical connections and mechanical mounting features allows competent users to complete the retrofit independently, improving accessibility while maintaining adequate installation quality.
