Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a rigid separation blade is used for particle separation, then separation effectiveness is improved, but mechanical force requirements increase and hull strength is reduced

Engineering Contradiction:
Improveparticle separation effectivenessVSAvoidhull strength
Core Design Contradiction:
Manufacturing precisionVSStrength

Solution Approach 1:

The patent replaces the rigid mechanical separation blade with a flexible membrane that utilizes hydrodynamic forces and pressure differentials to achieve particle separation. The membrane deflects under pressure to allow particles to pass through while maintaining hull integrity, eliminating the need for high mechanical force systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent employs a flexible membrane instead of a rigid blade for particle separation. The membrane can deflect and adapt to pressure changes, allowing effective particle separation while maintaining the structural strength of the hull, as it does not require the same mechanical support infrastructure as rigid blades.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of operation

If the particle separation chamber is open to the environment, then access is easier, but pressure control and separation efficiency are reduced

Engineering Contradiction:
