Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If adhesive tape is used to fix information on partitions, then information can be displayed, but adhesive tape remains on the partition and reduces space in the hall

Engineering Contradiction:

Improveease of information displayVSAvoidadhesive tape remains

Core Design Contradiction:

Ease of operationVSLoss of substance

Solution Approach 1:

The patent replaces the mechanical adhesive system with an electrostatic attraction system. The electrostatic chuck generates electrostatic force to attract and hold information displays without physical contact or adhesive materials, eliminating tape residue and simplifying removal and repositioning operations

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If notice boards are brought into the hall to display information, then information can be displayed, but space in the hall is reduced

Engineering Contradiction:

Improveease of information displayVSAvoidspace in the hall

Core Design Contradiction:

Ease of operationVSArea of stationary object

Solution Approach 1:

The electrostatic chuck serves multiple functions: it can attract and hold various types of information displays, can be positioned on different surfaces (partitions, walls, pillars), and can be easily moved and repositioned. This multi-functionality eliminates the need for dedicated notice boards, reducing space occupation while maintaining information display capability

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If simple dust collecting filters are set up at the outside-air inlet, then the system is simple, but powder contaminants cannot be collected sufficiently

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent replaces mechanical filtration with electrostatic attraction. The electrostatic chuck generates an electric field that attracts and captures powder contaminants through electrostatic force, achieving superior dust collection efficiency compared to simple mechanical filters while maintaining system simplicity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If a large-size cyclone dust collecting apparatus is used, then dust collection function is strong, but it is difficult to secure set-up space and maintenance of filters imposes significant load

Engineering Contradiction:

Improvedust collection functionVSAvoidset-up space

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The patent replaces the large-size mechanical cyclone system with a compact electrostatic attraction system. The electrostatic chuck can be implemented in a much smaller form factor while providing effective dust collection through electrostatic forces, significantly reducing the space required for installation and maintenance

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
