Notched Wire Remote Control Assembly Structural Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote control assemblies experience movement and deformation issues between wires, sheaths, and liners, which affect the transmission of motion and structural integrity.
Innovation Solution
A remote control assembly design featuring a wire with a plurality of notches separated into groups, where the second distance between notches is greater than the first, providing enhanced engagement with the sheath and liner to reduce movement and deformation, and secure the conduit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If current wire designs are used, then some structural support is provided, but deformation of sheath and liner occurs during wire movement
Solution Approach 1:
The notched wire design creates a flexible yet stable structural support system. The notches allow the wire to flex and bend without creating concentrated stress points that would deform the sheath or liner. The distributed notch pattern provides structural reinforcement while maintaining flexibility, preventing the wire from imposing harmful deformation forces on the surrounding components during movement or installation.
2Ease of manufacture
If uniform notch spacing is used, then manufacturing is simplified, but engagement effectiveness is reduced
Solution Approach 1:
The notch pattern employs asymmetric grouping where the first group of notches and the second group of notches are positioned at different locations along the wire. This asymmetric arrangement creates optimized engagement zones that enhance mechanical interlocking with the sheath and liner. The non-uniform distribution provides superior engagement effectiveness compared to uniform spacing, as it creates varying contact points that better accommodate the geometry and movement characteristics of the remote control assembly components.

AI summary
A remote control assembly includes a sheath (22) having a longitudinal axis along a length thereof and defining an interior. A liner (28) is disposed within the interior and coupled to the sheath. A wire (34) has an outer surface and the wire disposed between and coupled to the sheath and the liner. The outer surface of the wire defines a plurality of notches (42) separated into a first group of notches and a second group of notches. Each notch within each of the first and second groups defines a first distance therebetween substantially along the longitudinal axis. The first group of notches and the second group of notches define a second distance therebetween. The second distance is greater than the first distance.
