LED Cable Clamp Structure for Connector Heat and Seepage Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices face issues in protecting the connector and cable from external agents like seepage and mechanical damage, as well as preventing them from touching parts with dangerous operating temperatures.
Innovation Solution
A cable clamp device is designed to support and protect the connecting cables, incorporating a moulded plate with compartments for the connector and cables, snap coupling to the power supply unit housing, and teeth for secure engagement, ensuring the connector is shielded from external influences and dangerous temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the connector and cable are exposed in the lighting device, then the device complexity is reduced, but the reliability deteriorates due to vulnerability against external agents such as seepage and mechanical damage
Solution Approach 1:
The connector is nested within a dedicated compartment formed in the support device, which itself is integrated into the housing structure. This nested arrangement protects the connector from external agents while maintaining a compact overall structure without adding significant complexity.
Solution Approach 2:
The support device acts as an intermediary structure between the connector and the external environment. It provides a protective barrier against seepage and mechanical damage while facilitating the connection between power supply and LED module, thus improving reliability without proportionally increasing device complexity.
2Length of moving object
If the connector is placed close to the power supply unit, then the cable length is reduced, but the reliability worsens due to exposure to dangerous operating temperatures
Solution Approach 1:
The connector is nested within a thermally isolated compartment in the support device, allowing it to be positioned near the power supply unit for short cable length while the compartment structure provides thermal protection against dangerous operating temperatures.
Solution Approach 2:
The support device provides localized thermal protection through its compartment structure and material selection, creating a safe thermal environment for the connector in the specific location where it interfaces with the power supply, while maintaining short cable length.
3Reliability
If a protective structure is added for the connector, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The protective function for the connector is merged with the support device structure that already exists in the lighting device. The compartment formed in the support device serves both structural support and protective functions, improving reliability without adding separate complex protective mechanisms.
Solution Approach 2:
The support device is designed with multi-functionality, serving as both the structural support for the connector and the protective barrier against external agents. This universal structure improves reliability while minimizing additional complexity by combining multiple functions in a single component.
