Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical sheath end pieces for motor vehicle door opening cables are difficult to handle, making mounting and dismounting operations challenging, often requiring tools and increasing the complexity of maintenance tasks.
Innovation Solution
A sheath end piece with a base, mounting element, and dismounting element that facilitate easy attachment and detachment by providing a fastening interface for mounting and traction interface for dismounting, respectively, allowing for ergonomic and tool-free or tool-assisted operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If typical sheath end pieces are used, then the cable can be fastened to the opening device, but the handling and mounting operations become difficult and complex
Solution Approach 1:
The sheath end piece is segmented into distinct functional elements: a base portion that interfaces with the sheath, a mounting element with bearing surface for positioning, and a dismounting element with traction surface for removal. This segmentation allows each element to perform its specific function optimally, making the overall device easier to handle and mount.
Solution Approach 2:
The mounting element acts as an intermediary between the user's hand and the fastening interface, providing a bearing surface that distributes pressure and enables precise positioning. Similarly, the dismounting element serves as an intermediary for applying traction force during removal, eliminating the need for tools.
2Ease of operation
If typical sheath end pieces are used, then the cable connection is established, but tool-free dismounting becomes impossible
Solution Approach 1:
The dismounting element is designed to be gripped directly by the user's fingers, allowing the cable to be removed without external tools. The traction surface provides sufficient friction and leverage for manual removal, enabling maintenance personnel to perform dismounting operations independently and quickly.
3Manufacturing precision
If mounting element with bearing surface is added, then mounting precision is improved, but device structure becomes more complex
Solution Approach 1:
The mounting element is merged with the base portion of the sheath end piece, forming an integrated structure. The bearing surface is incorporated into this unified component, providing alignment functionality without requiring separate adjustment mechanisms or complex assembly steps.

AI summary
A sheath end piece of a connecting element that connects two vehicle door opening devices includes a base, a mounting element, and a dismounting element. The connecting element includes a cable which is partially covered with a sheath. The base is mounted on an end portion of the sheath and includes a fastening interface to permit the mounting and dismounting of the connecting element on one of the two door opening devices. The mounting element permits exerting a pressure on the fastening interface so as to permit the mounting of the connecting element. The dismounting element permits exerting a traction on the fastening interface so as to permit the dismounting of the connecting element. At least one of the mounting element and the dismounting element protrudes from the base.
