Solution Overview

Problem

Conventional signal cables with bulky connector components hinder the design of slim electronic devices and incur additional production costs, while lacking secure connection mechanisms that prevent easy disconnection.

Innovation Solution

A signal cable with a cable locking portion integrated into the cable film, which engages with a cable holder in the connector, allowing for secure connection and disconnection by applying a pulling force in a direction intersecting the connecting direction, using a grip unit to release the locking portion from the holder.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a connector component is provided at the end of the signal cable, then the connection to the cable connector is secure, but the connector component becomes bulky and hinders the design of slim electronic apparatuses

Engineering Contradiction:
Improveconnection securityVSAvoidcable end size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The cable locking portion is integrated directly into the cable film structure, merging the locking function with the cable body. This eliminates the need for separate bulky connector components at the cable end, allowing slim electronic apparatus design while maintaining secure connection through the integrated locking mechanism that engages with the cable holder.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a connector component is provided at the end of the signal cable, then the connection is secure, but production costs increase

Engineering Contradiction:
Improveconnection securityVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The locking function is merged into the cable film through the cable locking portion, eliminating the need for separate connector components. This integration reduces the number of parts required, simplifies the manufacturing process, and lowers production costs while maintaining secure connection through the engagement between the cable locking portion and cable holder.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The separate connector component is extracted from the cable assembly, with its essential locking function being transferred to the integrated cable locking portion in the cable film. This extraction eliminates unnecessary components and reduces production complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If no connector component is provided, then production costs are reduced and design is simplified, but the signal cable easily becomes disconnected

Engineering Contradiction:
Improveproduction costVSAvoidconnection stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The locking function is merged into the cable film structure through the cable locking portion, providing connection stability without requiring separate connector components. This integration maintains reliability by creating a secure engagement mechanism with the cable holder while keeping production simple and costs low.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cable locking portion provides self-service locking by automatically engaging with the cable holder when the cable is inserted. The grip unit enables easy disconnection when needed, creating a self-service connection system that maintains stability without complex components or additional costs.

Inventive Principle:
Principle #25Self-service

4Volume of moving object

If a cable locking portion is integrated into the cable film, then connection security is maintained without bulky components, but the cable may still disconnect under external forces

Engineering Contradiction:
Improvecable end sizeVSAvoidresistance to external forces
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The grip unit is configured to be bowed upwardly, creating a curved structure that provides mechanical advantage. When the user grips and pulls the free end, the bowed shape amplifies the pulling force, enabling reliable disconnection. This curvature also provides a comfortable grip area that concentrates force effectively.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The cable locking portion provides dynamic connection characteristics - automatically engaging and locking when inserted to resist external forces during normal use, yet allowing easy disconnection when the grip unit is pulled. This creates a dynamic system that adapts to different operational states.

Inventive Principle:
Principle #15Dynamics
