Solution Overview

Problem

Existing cable connectors with optical members face issues due to springs that can arc-shapedly transform and fly out of retaining slots, disrupting assembly and stability.

Innovation Solution

A cable connector design featuring an insulative housing with a positioning block and springs that are assembled within the housing, preventing the springs from flying out and ensuring horizontal force retention, along with a retaining member that abuts against the optical member and a positioning block to maintain assembly stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If springs are assembled in the retaining slot to retain the optical member, then the optical member can be held in position, but the springs may arc-shapedly transform and fly out of the retaining slot, disrupting assembly and stability

Engineering Contradiction:
Improveretention of optical memberVSAvoidspring displacement and flying out
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

A positioning block is introduced as an intermediary component between the springs and the optical member. The positioning block has a U-shaped structure that confines the springs horizontally, preventing them from flying out while still allowing them to perform their retention function. The positioning block is inserted into the insulative housing and horizontally retains the springs, solving the problem of spring displacement without compromising the retention of the optical member.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the spring is allowed to transform elastically to retain the optical member, then the optical member can be securely held, but the spring may move out of position and affect assembly

Engineering Contradiction:
Improvesecure retention of optical memberVSAvoidease of assembly
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The retention system is segmented into three distinct functional components: the springs (providing elastic retention force), the positioning block (confining the springs horizontally), and the insulative housing (providing the structural framework). This segmentation allows each component to perform its specific function independently - the springs can transform elastically to retain the optical member while the positioning block prevents them from moving out of position, thus maintaining both secure retention and ease of assembly.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If the spring is constrained to prevent flying out, then assembly stability is improved, but the spring's elastic transformation capability may be restricted

Engineering Contradiction:
Improveassembly stabilityVSAvoidspring elastic transformation
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The positioning block provides localized horizontal constraint to the springs, while leaving their vertical elastic transformation capability intact. The U-shaped structure of the positioning block confines the springs in the horizontal direction to prevent flying out, but allows them to compress and expand vertically to perform their retention function. This local quality approach maintains assembly stability through horizontal confinement while preserving the spring's adaptability through vertical elastic transformation.

Inventive Principle:
Principle #3Local quality
