Solution Overview

Problem

Existing push-pull connectors require excessive force and abrupt release when disconnecting from sockets, making it difficult to meter and estimate the force required for separation.

Innovation Solution

A securing element with a cylindrical base, guide wall, and resilient spring design that allows for controlled disengagement by moving the spring along the connection direction, reducing the force needed for actuation and enabling easier and more precise separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a securing element with securing lugs is used to prevent detachment, then connection reliability is improved, but excessive force is required for separation

Engineering Contradiction:
Improveconnection reliabilityVSAvoidseparation force
Core Design Contradiction:
ReliabilityVSForce

Solution Approach 1:

The securing element incorporates a resilient spring that can dynamically change its state between engaged and disengaged positions. The spring's elasticity allows it to flex during connection and release during disconnection, transforming the static securing mechanism into a dynamic one that requires less force for separation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring's physical state changes during operation - compressed during engagement and extended during disengagement. This parameter change allows the securing element to transition between high-strength connection and low-force release states, resolving the contradiction between connection reliability and separation force.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If traditional securing elements are used, then connection stability is maintained, but the release process becomes abrupt and unpredictable

Engineering Contradiction:
Improveconnection stabilityVSAvoidrelease control
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The resilient spring provides a gradual transition during release by flexing and extending progressively rather than snapping abruptly. This dynamic behavior allows the operator to control the release process smoothly, transforming an unpredictable abrupt release into a controlled gradual disengagement.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring acts as a cushioning element that absorbs and distributes the release energy gradually. By pre-positioning this elastic element, the system prepares for a controlled release that prevents sudden jerky movements, improving ease of operation while maintaining connection stability during use.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Strength

If securing lugs engage firmly in the socket, then connection strength is improved, but force metering becomes difficult

Engineering Contradiction:
Improveconnection strengthVSAvoidforce metering
Core Design Contradiction:
StrengthVSMeasurement precision

Solution Approach 1:

The spring's gradual extension during release provides a measurable parameter change that can be used to estimate the force required. By observing the spring's deflection and extension progress, operators can meter and estimate the separation force, transforming an unmeasurable abrupt force into a gradually varying measurable parameter.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The spring's physical state during engagement and disengagement provides visual and tactile feedback about the force being applied. This feedback mechanism allows operators to sense and estimate the required separation force, improving force metering precision while maintaining strong connection during use.

Inventive Principle:
Principle #23Feedback
