Control Cable Slider Connection for Simple Coaxial Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control cable connection structures require complex shapes and additional forces for connection, increasing fabrication costs and the burden of connection work due to the need for resilient pawls and protrusions, making them difficult to process and assemble.
Innovation Solution
A control cable connection structure featuring a simple slider and cable end design, where the slider is anchored to a case and allows for coaxial connection of inner cords without requiring additional forces, using a cable end that connects with the slider from the opposite side, reducing the complexity of components and assembly burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a resilient pawl is formed at the coupling piece to prevent disengagement, then the connection reliability is improved, but the device complexity and fabrication costs increase
Solution Approach 1:
The resilient pawl structure is extracted and replaced by a simple protrusion structure. The engagement mechanism is simplified by removing the resilient component and using only a rigid protrusion that engages with a corresponding recess, thereby reducing device complexity while maintaining connection reliability.
Solution Approach 2:
The resilient pawl, which requires precision manufacturing and has complex geometry, is replaced by a simpler protrusion structure that is easier and cheaper to manufacture. The simplified structure achieves the same functional goal without the need for resilient materials or complex forming processes.
2Reliability
If a protrusion portion is formed at the coupling piece for pawl engagement, then the connection reliability is improved, but the fabrication costs and processing difficulty increase
Solution Approach 1:
The complex pawl engagement system with resilient components is extracted and replaced by a simpler protrusion-recess engagement system. This removes the need for precision resilient component manufacturing while maintaining reliable engagement through the simplified geometric features.
3Reliability
If additional forces are applied during connection to ensure tight fitting, then the connection reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The connection structure is designed to self-align and self-engage through the protrusion-recess mechanism. The geometric features guide the coupling pieces into proper alignment and automatically engage without requiring additional forcing or complex alignment procedures, thereby maintaining ease of operation while ensuring reliable connection.

AI summary
A control cable connection structure includes a long, narrow casing, a casing end, a cable end and a slider. An end portion of a first conduit is anchored at one end portion, in a length direction, of the casing. An end portion of a second conduit is anchored at the casing end. The casing end is superposed and assembled with the casing in a radial direction of the second conduit. The cable end is attached to an end portion of a second inner cord. An end portion of a first inner cord is anchored at the slider. The slider is supported at the casing to be slidable in the length direction thereof. In the assembled state, the cable end is engaged with the slider at an opposite side from a side at which the second conduit is disposed, and the second inner cord is connected with the slider.
