Harness connection structure and electronic device

Solution Overview

Problem

Existing harness connection structures for movable members in electronic devices fail to ensure reliable electrical connection and prevent damage during storage and pulling out, as they lack effective suppression mechanisms for harness movement.

Innovation Solution

A harness connection structure with a first suppressing portion on the apparatus main body and a second suppressing portion between the main body and the movable member, ensuring the harness is fixed and wound around the first suppressing portion, preventing overhanging and damage by maintaining a consistent length regardless of the movable member's position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the harness is loosely connected to allow movement during pulling out, then ease of operation is improved, but reliability of electrical connection deteriorates due to potential disconnection or damage

Engineering Contradiction:

Improveease of pulling outVSAvoidelectrical connection reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The harness connection structure employs dynamic elements including a movable member that can be pulled out and stored, with the harness dynamically adjusting its position through suppressing portions that allow controlled movement while maintaining connection. The first suppressing portion moves with the movable member during pull-out operations, while the second suppressing portion provides stable positioning during storage.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The suppressing portions act as intermediary elements between the harness and the movable member/apparatus main body. These intermediaries control and guide the harness movement, preventing direct contact and potential damage between the harness and moving parts while ensuring reliable electrical connection throughout the pull-out and storage cycles.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the harness is tightly fixed to prevent movement, then reliability of electrical connection is improved, but ease of operation deteriorates due to restricted movement during pulling out

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidease of pulling out

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

3Ease of operation

If the harness is allowed to move freely during storage and pulling out, then ease of operation is improved, but the harness may contact other parts causing damage

Engineering Contradiction:

Improveease of movementVSAvoidharness damage from contact

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The suppressing portions act as intermediary elements between the harness and the movable member/apparatus main body. These intermediaries control and guide the harness movement, preventing direct contact and potential damage between the harness and moving parts while ensuring reliable electrical connection throughout the pull-out and storage cycles.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The suppressing portions provide preliminary restraint to the harness, preventing it from moving into positions where it could contact other parts and suffer damage. The first suppressing portion on the apparatus main body and the second suppressing portion on the movable member work together to pre-establish boundaries that protect the harness during pull-out and storage operations.

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

A harness connection structure electrically connects a main body and a movable member with a harness to each other. The movable member is provided such that the movable member can be pulled out with respect to the main body. The harness connection structure includes a harness having one end fixed to a front side of one surface of the main body in a pull-out direction of the movable member, the one surface of the main body facing one surface of the movable member with a gap, and the other end fixed to a back side of the movable member in a pull-out direction of the movable member, a first suppressing portion provided on the one surface of the main body and suppressing a movement of the harness to a pull-out side of the movable member, and a second suppressing portion suppressing a movement of the harness toward the movable member between the one surface of the movable member and the one surface of the main body.
