Solution Overview

Problem

Existing cable manufacturing methods with connectors face disconnection issues during maintenance of substrate processing apparatuses, particularly due to the detachment of connectors, which affects the reliability and efficiency of temperature sensing and control systems.

Innovation Solution

A method for manufacturing a cable with a connector that includes attaching a contact to a reinforcing wire, which is then inserted into a housing connected to one end of the cable, and secured using a binding band, ensuring the reinforcing wire is tensely stretched while the lead wires are loosely stretched, thereby preventing disconnection and maintaining the cable's diameter.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the connector is detached during maintenance, then the connector can be removed for servicing, but the lead wires may become disconnected

Engineering Contradiction:

Improveconnector detachabilityVSAvoidlead wire connection stability

Core Design Contradiction:

Ease of repairVSReliability

Solution Approach 1:

The cable assembly is segmented into modular components: the connector, the lead wires, and the reinforcing wire. This allows the connector to be detached for maintenance while the reinforcing wire remains secured to the lead wires, preventing complete disconnection

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The reinforcing wire acts as an intermediary element between the connector and the cable body. It provides continuous structural support and prevents lead wire disconnection even when the connector is removed, serving as a mediator that maintains connection integrity

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the reinforcing wire is tightly secured to prevent disconnection, then connection reliability improves, but the cable diameter increases

Engineering Contradiction:

Improveconnection stabilityVSAvoidcable diameter

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

The reinforcing wire is positioned locally at the connector end of the cable where mechanical stress and disconnection risk are highest. This localized reinforcement provides maximum connection stability without requiring the entire cable to have increased diameter

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The reinforcing wire has a thin, flexible structure that provides sufficient mechanical strength to prevent disconnection while maintaining a minimal cross-sectional area, thus avoiding significant increase in cable diameter

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A method for manufacturing a cable with a connector is provided. In the method, a contact is attached to a reinforcing wire. The reinforcing wire to which the contact is attached is inserted into an insertion portion of a housing. The housing is connected to one end of a cable. The reinforcing wire is secured to the cable by a securing member.
