Solution Overview

Problem

The existing coupling bushing and plug designs require cumbersome handling, necessitating one hand to hold each component and requiring a spring to be pushed back, which is inconvenient in confined spaces like motor vehicle compartments where space is limited.

Innovation Solution

A coupling bushing and plug design where the latching element is resiliently elastic, allowing it to store reset energy and simplify handling by eliminating the need for a separate spring, enabling the coupling plug to be locked with one hand by merging the two components, thus eliminating the need for separate handling of each part.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a spring-loaded retainer is used to lock the coupling plug, then the coupling assembly can be securely locked, but the handling becomes cumbersome requiring two hands and pushing the sleeve back against spring force

Engineering Contradiction:
Improvelocking reliabilityVSAvoidhandling ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts the spring component from the coupling assembly by replacing it with a resiliently elastic latching element that stores reset energy through its own elasticity. This eliminates the separate spring mechanism while maintaining the locking function, thereby simplifying handling to one-handed operation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the spring function with the latching element by designing the latching element to be resiliently elastic. This combination integrates the energy storage and locking functions into a single component, eliminating the need for a separate spring and reducing the number of parts that require manual manipulation.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of repair

If a separate spring is used for resetting the latching mechanism, then the valve can be reset, but the device complexity increases with additional components

Engineering Contradiction:
Improvevalve reset capabilityVSAvoidnumber of components
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The patent merges the spring function with the latching element by designing the latching element to be resiliently elastic. This combination integrates the energy storage and locking functions into a single component, eliminating the need for a separate spring and reducing the number of parts that require manual manipulation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The resiliently elastic latching element serves itself by storing reset energy through its own elasticity when deformed during insertion. This self-service mechanism eliminates the need for a separate spring component, simplifying the overall device structure while maintaining the reset capability.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the latching element is made resiliently elastic to store reset energy, then handling is simplified, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvehandling easeVSAvoidelasticity control
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by selecting appropriate material properties for the latching element to achieve the desired elasticity. By carefully choosing materials with suitable elastic characteristics, the design achieves one-handed operation capability while maintaining manufacturability through standard material selection and processing techniques.

Inventive Principle:
Principle #35Parameter changes
