Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable supporting devices for automotive slide doors are limited in their ability to accommodate wide ranges of vertical, transverse, and oblique angular changes, often resulting in cable twisting and increased part complexity, and require specific mounting positions and angles for different vehicle types.
Innovation Solution
A cable supporting device featuring a guide member with a three-dimensional surface and a supporting member with an arcuate contact surface, allowing the cable to change angles over wide ranges by restricting rotational angles through surface contact, reducing the likelihood of twisting and simplifying assembly across various vehicle configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cable supporting device uses a fixed mounting position and angle for different vehicle types, then the device structure can be simplified, but the cable cannot accommodate wide ranges of vertical, transverse, and oblique angular changes, resulting in cable twisting
Solution Approach 1:
The cable supporting device incorporates a rotating member that can rotate about a rotation axis, enabling the device to dynamically adjust its orientation to accommodate wide ranges of vertical, transverse, and oblique angular changes. This dynamic capability allows the cable to follow the rotating member's movement without twisting, while maintaining a relatively simple overall device structure.
2Adaptability or versatility
If the cable supporting device allows wide angular changes, then the cable can accommodate different vehicle types, but the device complexity increases due to multiple link members and connection pins
Solution Approach 1:
The rotating member serves multiple functions: it accommodates vertical angular changes, transverse angular changes, and oblique angular changes simultaneously. By consolidating these multiple angular adjustment functions into a single rotating mechanism, the device achieves universal compatibility across different vehicle types without requiring complex assemblies of multiple link members and connection pins.
3Strength
If the cable supporting device restricts vertical rotational angular range, then the link member can maintain structural integrity, but it takes time to consider mounting position and angle for each vehicle type
Solution Approach 1:
The device enables change in the rotational angular range parameter by allowing the rotating member to rotate about a rotation axis, thereby accommodating wide ranges of vertical, transverse, and oblique angular changes. This parameter change allows the same device to be used across different vehicle types without requiring time-consuming considerations of mounting position and angle for each specific vehicle.
4Ease of operation
If the cable supporting device uses orthogonal connection pins for vertical and transverse rotation, then the mechanism can follow angular changes, but the cable cannot make transverse swinging movement at positions proximate to the supporting member, causing twisting
Solution Approach 1:
The cable supporting device introduces a rotation axis that extends in a direction different from both the vertical and transverse directions (i.e., in oblique direction). This dimensional change allows the cable to swing freely in all three directions (vertical, transverse, and oblique) without restriction, eliminating the twisting problem that occurs with orthogonal connection pins limited to two-dimensional rotation.

Function Achieved in This Case
The device effectively supports cables through wide angular changes without twisting, enhancing versatility and reducing the need for precise mounting adjustments, thus protecting the cable from excessive bending or twisting and simplifying manufacturing and installation.

AI summary
A device for supporting a cable between a vehicle body and a movable member movably connected to the vehicle body is provided with a guide including a frame having a three-dimensional outer surface and a supporting member for rotatably tightly holding the arcuate surface of the guide, the support being fixed to the vehicle body and/or the movable member. The frame of the guide includes a first opening and a second opening communicating with a hollow portion thereof and used for insertion of the cable, a tube projecting from the peripheral edge of the first opening and a rotational angle restriction projecting from the outer surface of the frame while being spaced apart by a required angle from the tube. The support includes a contact engageable with the rotational angle restriction, and at least one of facing surfaces of the contact and the rotational angle restriction is an inclined surface.
