Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rigid connection is used for plug-in members, then structural strength is improved, but stability under vibration is worsened

Engineering Contradiction:
Improvestructural strengthVSAvoidconnection stability
Core Design Contradiction:
StrengthVSStability of the object's composition

Solution Approach 1:

The plug-in member incorporates an elastic component that enables dynamic adaptation to vibrations while maintaining structural integrity. The elastic component deforms under vibration forces and returns to its original position, providing both strength and vibration resistance.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic component is pre-configured to absorb and cushion vibration forces before they can cause damage or disconnection. This beforehand cushioning prevents the harmful effects of vibrations on the rigid connection structure.

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

2Stability of the object's composition

If floating connection is increased for vibration absorption, then connection stability is improved, but liquid sealing is worsened

Engineering Contradiction:
Improveconnection stabilityVSAvoidliquid sealing
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

A sealing component acts as an intermediary between the floating connection and the liquid flow path. This sealing element compensates for the gaps created by floating movement while maintaining liquid tightness, thus mediating between the conflicting requirements of floating connection and sealing.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The sealing component utilizes flexible material that can deform with the floating movement of the plug-in member. This flexible sealing element maintains contact and sealing effectiveness despite the positional changes caused by vibration absorption.

Inventive Principle:
Principle #30Flexible shells and thin films

3Stability of the object's composition

If elastic components are added to enhance float, then vibration resistance is improved, but device complexity is worsened

Engineering Contradiction:
Improvevibration resistanceVSAvoidstructure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The elastic component is integrated into the plug-in member structure itself rather than being a separate assembly. This merging of functions allows the plug-in member to simultaneously provide structural support, floating connection, and vibration absorption without adding separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The elastic component serves multiple functions: it provides the floating connection capability, absorbs vibrations, maintains sealing contact, and supports the liquid flow path. This multi-functionality reduces the need for additional specialized components.

Inventive Principle:
Principle #6Universality (Multi-functionality)
