Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp module groups lack effective heat dissipation and waterproofing, leading to reduced service life and increased waste due to overheating and water ingress, especially when used outdoors.
Innovation Solution
The electronic module group incorporates a concentric terminal system with a first and second housing that conducts heat and provides rotational coaxial power transmission, combined with sealing layers and a concentric terminal structure for waterproofing, allowing for modular replacement of failed components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a module group structure is adopted to facilitate maintenance and save costs, then the cost of replacement is reduced and maintenance is simplified, but the module group lacks waterproof function and cannot meet outdoor work requirements
Solution Approach 1:
The lamp is divided into a waterproof lamp housing and a separate non-waterproof module group (LED lamp board and power supply). The module group can be easily replaced when damaged, while the waterproof housing maintains protection. This segmentation resolves the contradiction by allowing easy maintenance through module replacement while preserving waterproof capability through the dedicated housing structure.
2Device complexity
If the module group is designed without waterproof function to simplify structure, then manufacturing complexity is reduced, but heat dissipation capability is insufficient leading to reduced service life
Solution Approach 1:
A heat dissipation plate is introduced as an intermediary component between the power supply and the lamp housing. The heat dissipation plate conducts heat away from the power supply module, while the lamp housing provides additional heat dissipation surface area. This intermediary structure enables effective heat dissipation without significantly increasing the overall structural complexity.
3Adaptability or versatility
If the module group is integrated into the lamp housing to form a complete lamp, then the lamp can function as a complete unit, but when the module group fails the entire lamp must be replaced increasing cost and waste
Solution Approach 1:
The lamp is segmented into a permanent waterproof housing and a replaceable module group. When the module group fails, only the module group needs to be replaced while the housing remains in use. This segmentation reduces material waste compared to replacing the entire lamp, while maintaining the functional integration of the complete lamp system.
4Reliability
If sealing layers are added to provide waterproofing, then waterproof capability is improved, but heat dissipation efficiency is reduced due to additional thermal resistance
Solution Approach 1:
The lamp housing is designed with differentiated local qualities: the main housing structure provides waterproof protection with sealing layers, while specific regions (outer surface and designated heat dissipation areas) are optimized for thermal radiation and convection. This local quality differentiation allows the housing to simultaneously provide waterproofing and effective heat dissipation without the sealing layers completely blocking thermal pathways.
