Solution Overview

Problem

The existing connector locking wire operating mechanisms do not adequately address the impact of a rapidly rebounding elastic member on the push rod, which can cause injury to operators during the unlocking process.

Innovation Solution

A mechanism featuring a push rod and cam with a sector notch and damping stopper wall, allowing the cam to rotate and buffer the impact of the spring plate's rebound, reducing the force transmitted to the push rod and operator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the push rod is rotated to unlock the spring plate, then the spring plate is loosened and reset, but the impact on the push rod caused by the rapidly rebounding elastic member may cause injury to the operator

Engineering Contradiction:

Improveunlocking operationVSAvoidimpact on operator

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cam acts as an intermediary between the spring plate and the push rod. When the spring plate rebounds, it pushes the cam which rotates within the sector notch, and this cam then transmits a buffered force to the push rod. This intermediary mechanism absorbs and distributes the impact energy, preventing direct transmission of the full rebound force to the operator's finger on the push rod.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The sector notch is designed with sufficient space beforehand to accommodate the cam's rotation during spring plate rebound. This pre-designed spatial buffer allows the cam to rotate freely when impacted by the rebounding spring plate, cushioning the impact before it reaches the push rod. The notch's dimensions are specifically calculated to provide this protective buffering capacity.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Productivity

If the spring plate rebounds instantly and rapidly, then the locking wire hole closes quickly for locking, but the large impact may cause injury to the operator

Engineering Contradiction:

Improvelocking speedVSAvoidimpact on operator

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The cam serves as a mediator that decouples the direct connection between the spring plate and push rod. The spring plate can rebound rapidly to close the locking wire hole quickly, while the cam absorbs and buffers the impact energy during its rotation within the sector notch, preventing this rapid rebound from transmitting full impact force to the operator's finger on the push rod.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The sector notch is pre-designed with sufficient angular space to accommodate the cam's rotation during rapid spring plate rebound. This beforehand cushioning allows the system to maintain high locking speed while protecting the operator, as the cam can rotate freely within the notch boundaries without transmitting full impact to the push rod.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Device complexity

If the push rod and cam are of integrated structure, then the device is simpler, but the impact cannot be buffered effectively

Engineering Contradiction:

Improvestructure integrationVSAvoidimpact transmission

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The system is segmented into three distinct components: the spring plate, the cam, and the push rod. This segmentation allows the cam to function as an independent buffering element between the spring plate and push rod. The cam can rotate within the sector notch to absorb impact energy, which would not be possible if the push rod and spring plate were directly integrated without an intermediate buffering component.

Inventive Principle:

Principle #1Segmentation

AI summary

A connector locking wire operation mechanism capable of buffering an impact on a push rod includes a body provided with a push rod rotatable along an arcuate track and a cam rotatable about a circular hole. A sector notch capable of accommodating the cam and leaving sufficient space is provided at an inner side of the push rod. The push rod and the cam are cooperatively rotatable about a common rotation axis. Both sides of the cam are in contact with the push rod and a spring plate respectively.
