Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a longer static electricity eliminating section is used to allow charges to move from the center portion to the inner wall, then static electricity elimination effectiveness is improved, but device complexity and structure size increase

Engineering Contradiction:

Improvestatic electricity elimination effectivenessVSAvoidstructure size

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The eliminating section is divided into multiple sections with different inner wall conductivity configurations. Some sections have highly conductive inner walls while others have low-conductive nonmetallic material, creating a segmented structure that optimizes charge elimination without requiring excessive length.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the eliminating section have different electrical conductivity properties. The inner wall conductivity is locally optimized - highly conductive in areas where charge transfer is needed, and low-conductive in areas where fluid containment is prioritized, allowing effective charge elimination in a compact structure.

Inventive Principle:

Principle #3Local quality

2Reliability

If a metallic mesh or filter is used to contact fluids in the center portion, then static electricity elimination is improved, but risk of metal contamination increases

Engineering Contradiction:

Improvestatic electricity eliminationVSAvoidmetal contamination risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention uses nonmetallic eliminating sections that can be easily replaced if contamination occurs, rather than permanent metallic structures. These nonmetallic sections serve the static elimination function without posing contamination risks.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The eliminating section uses composite construction with nonmetallic materials that provide both fluid containment and static electricity elimination capabilities, eliminating the need for metallic mesh while maintaining effectiveness.

Inventive Principle:

Principle #40Composite materials

3Reliability

If a thicker mesh or filter with lower resistance is used, then static electricity elimination is improved, but pressure loss of fluids increases

Engineering Contradiction:

Improvestatic electricity eliminationVSAvoidpressure loss

Core Design Contradiction:

ReliabilityVSStress or pressure

Solution Approach 1:

The invention optimizes the conductivity parameter of the inner wall material and the geometric parameters of the eliminating section to achieve effective charge elimination with minimal impact on fluid flow resistance, balancing static elimination effectiveness with pressure loss constraints.

Inventive Principle:
