Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connectors used in machine tools with high oil usage lack oil resistance, leading to oil leakage and malfunction.
Innovation Solution
A connector design featuring a cable with a cohesion unit on its insulation surface, fixed to a cover unit via cohesive fracture, preventing oil ingress between the cable and cover unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connector uses a simple cord and body structure without special oil resistance design, then the device complexity is low and ease of manufacture is high, but oil resistance is poor and reliability in oily environments deteriorates
Solution Approach 1:
The cohesion unit is pre-formed on the cable insulation surface before assembly, creating a protruding structure that will later prevent oil infiltration. This preliminary structural preparation ensures oil resistance without requiring complex additional components during operation.
Solution Approach 2:
The cohesion unit is positioned specifically at the cable end where it contacts the cover unit, creating a localized barrier against oil infiltration. This targeted structural modification at the critical interface point provides effective oil resistance without complicating the entire connector structure.
2Reliability
If the connector uses a simple cord and body structure, then the ease of manufacture is high, but the durability and long-term oil resistance deteriorates
Solution Approach 1:
The cohesion unit is formed during cable manufacturing before connector assembly, integrating the oil resistance feature into the existing production流程. This approach maintains manufacturing efficiency while ensuring long-term oil resistance performance.
Solution Approach 2:
The cohesion unit modifies the surface geometry of the cable insulation by creating protrusions that extend beyond the insulation surface. This parameter change in surface topology provides a mechanical barrier against oil infiltration without requiring material composition changes or complex manufacturing processes.
3Reliability
If no cohesion unit is provided, then the device complexity is low, but oil infiltration occurs between the cable and cover unit causing malfunction
Solution Approach 1:
The cohesion unit creates localized protrusions on the cable insulation surface at the critical interface region with the cover unit. This localized structural enhancement provides effective oil infiltration prevention without requiring complex modifications throughout the entire cable structure.
Solution Approach 2:
The cohesion unit is pre-formed on the cable insulation before assembly into the connector. This preliminary structural preparation ensures that the oil barrier is already in place, preventing infiltration from the outset without requiring additional components or complex assembly procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The connector achieves high oil resistance by ensuring that oil cannot enter the connector body over time, enhancing its reliability in oily environments.

AI summary
A connector is provided with a cable that includes a conductor and an insulation, connector bodies that are provided on one ends in an extending direction of the cable, and a cover unit that covers and integrates each of the one ends of the cable and each of the connector bodies. The cable includes a first cohesion unit provided on a surface of the insulation at each of one ends over an entire circumference around the extending direction of the cable, and fixed to the cover unit so as to be detachable by cohesive fracture.
