Compact Power Slide Door Mechanism Using Integrated Cable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power slide door mechanisms for land vehicles require a larger space due to the presence of cable brackets, limiting their installation in smaller spaces and compatibility with non-power sliding doors.
Innovation Solution
A slide structure that eliminates the conventional cable bracket by securely attaching the cable to a roller hinge using a guide roller pin and cable end, allowing for a more compact design and compatibility with both powered and non-powered sliding doors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional cable bracket is used to attach the cable to the roller hinge, then the connection is secure and reliable, but the installation space requirement increases and packaging size becomes larger
Solution Approach 1:
The cable bracket is merged with the roller hinge assembly, integrating the cable attachment function directly into the roller hinge structure. This eliminates the need for a separate cable bracket component while maintaining secure cable connection, thereby reducing the overall installation space and packaging size.
Solution Approach 2:
The roller hinge assembly is designed to perform multiple functions: it provides the hinge function for door rotation, the roller function for guiding door movement, and the cable attachment function for power transmission. This multi-functional design eliminates the need for separate dedicated cable brackets, reducing space requirements.
2Strength
If a conventional cable bracket structure is used, then the cable attachment is robust, but the device complexity increases and compatibility with non-power sliding doors is reduced
Solution Approach 1:
The cable attachment function is combined with the roller hinge assembly, eliminating the need for a separate cable bracket. This integration reduces the number of components and simplifies the overall slide structure while maintaining robust cable attachment through the integrated design.
Solution Approach 2:
The simplified roller hinge assembly serves as a universal component that can be used in both power-operated and manual sliding door applications. The integrated design provides cable attachment capability when needed while maintaining structural simplicity for broader compatibility.
