Sliding Door Latch Linkage for Cable-Safe Full Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding door structures with a lower arm that turns can cause cable damage and hinder smooth operation due to cable swinging and changing door width as the door opens and closes, especially when a cable passing mechanism is used.
Innovation Solution
A sliding door structure incorporating a link mechanism with a latch member configured of a first member on the sliding door side and a second member on the vehicle body side, featuring a rod and rotating body that prevent twisting and unnecessary operation, ensuring smooth opening and closing without extra cable length generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cable passing mechanism under the lower arm is used, then the lock lever can be operated, but the cable swings around and may be damaged when the sliding door opens and closes
Solution Approach 1:
A guide groove is provided in the lower arm through which the cable passes. This guide groove acts as an intermediary structure that constrains the cable's movement path, preventing it from swinging around freely while still allowing the cable to transmit operating forces to the lock lever effectively.
2Ease of operation
If the lower arm turns with the sliding door, then the door can open and close smoothly, but the extra cable length hangs down and may damage the cable
Solution Approach 1:
The guide groove in the lower arm serves as a mediator that manages the cable's path during door movement. As the lower arm turns with the door, the guide groove ensures the cable follows a controlled trajectory, preventing excessive slack and hanging that could lead to cable damage.
3Adaptability or versatility
If the width between vehicle body and door changes during door movement, then the door can open and close, but the cable extra length hangs down causing operational issues
Solution Approach 1:
The guide groove acts as an intermediary structure that accommodates changes in door position and width variation. It maintains proper cable tension and alignment throughout the door's range of motion, preventing the cable from hanging down or operating unevenly.
