Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring devices for transmission cables are unsuitable for closed apertures and are difficult to mount and dismount, especially in restricted spaces, due to complex manual handling and potential for unintended release.
Innovation Solution
An anchoring device with a sleeve element and a coaxially movable ring member that forces resilient tangs radially inward, allowing easy mounting and dismounting regardless of rotational position and securing the cable effectively in any aperture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a securing member is used to anchor the cable sheath to a closed aperture, then the device can be mounted to closed apertures, but the handling of mounting and dismounting becomes very awkward and difficult
Solution Approach 1:
The anchoring device is segmented into a body with resilient tangs and a separate ring member that can be independently manipulated. The ring member acts as a tool to force the tangs inward, allowing the assembler to mount or dismount the device without directly manipulating the cable sheath or dealing with complex securing mechanisms. This segmentation enables easy operation while maintaining adaptability to closed apertures.
Solution Approach 2:
The ring member serves as an intermediary tool between the assembler and the resilient tangs. By inserting the ring member and applying longitudinal force, the assembler indirectly forces the tangs radially inward to clear the aperture edge, enabling mounting or dismounting without direct manipulation of the tangs themselves. This intermediary mechanism simplifies operation while enabling adaptation to closed apertures.
2Reliability
If manual holding back of the securing member is required during assembly, then the device can be secured to the bracket, but the mounting procedure cannot be performed quickly and easily
Solution Approach 1:
The resilient tangs automatically engage with the bracket aperture edge when the cable sheath is inserted, requiring no manual intervention to maintain securing contact. The tangs' elasticity provides automatic engagement and retention, eliminating the need for assemblers to manually hold back securing members during assembly. This self-service mechanism maintains reliability while significantly improving mounting speed and productivity.
Solution Approach 2:
Instead of using a securing member that must be held back and then released, the invention inverts the approach by using resilient tangs that automatically engage and secure the device. The tangs are forced inward during insertion and automatically spring back to engage the bracket, reversing the conventional sequence of manual securing and enabling quick, tool-free mounting without compromising reliability.
3Ease of operation
If legs are made flexible to enable insertion through aperture, then the legs can be forced radially inward, but the rotational position must be precisely controlled to ensure proper engagement
Solution Approach 1:
The resilient tangs are arranged radially around the body in a circular pattern, creating an asymmetric configuration relative to any single aperture orientation. This radial arrangement ensures that at least one tang will always be positioned to engage the aperture edge regardless of the device's rotational orientation, eliminating the need for precise rotational position control while maintaining ease of insertion.
Solution Approach 2:
The multiple resilient tangs serve multiple functions simultaneously: they enable easy insertion by flexing radially inward, provide automatic securing engagement with the bracket aperture edge, and ensure reliable anchoring regardless of rotational position. This multi-functional design eliminates the need for rotational position control mechanisms while maintaining ease of operation and reliability across all orientations.

AI summary
An anchoring device for anchoring a sheath of a transmission cable to a bracket may include a sleeve coaxially connectable to the sheath of the cable, the sleeve having a plurality of tangs extending longitudinally and arranged in a circular configuration, the tangs each having a transversal surface defining a wall of a circumferential groove, the groove being able to receive a bracket and to secure the sheath of the cable from longitudinal movements relative to the bracket, the anchoring device may include a ring longitudinally movable relative to the sleeve between first and second longitudinal positions, and wherein the ring is able to force the tangs to move inward upon movement of the ring from the first to the second longitudinal position such that the diameter of the wall of the circumferential groove is decreased.
