Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If masks are used to prevent electrochemical treatment of specific sections, then the isolated section is protected from unwanted treatment, but the treatment of objects with different diameters requires exchanging and manually adjusting masks, which is time-consuming and labor-intensive

Engineering Contradiction:
Improveisolation effectivenessVSAvoidtreatment efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The isolation apparatus employs movable segments that can dynamically adjust their position along guiding track ways to accommodate substrates of different diameters. The segments are translocatable relative to the substrate, allowing the isolation region to be adapted to various substrate sizes without manual mask exchange, thereby maintaining both isolation effectiveness and treatment efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The apparatus changes the parameter of isolation region diameter by moving the segments along the guiding track ways. This allows the isolation region to be adjusted to match the diameter of different substrates, eliminating the need for manual mask exchange while maintaining effective isolation.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If masks are used to isolate sections, then electrochemical treatment is prevented on isolated sections, but manual adjustment and replacement of masks exposes workers to noxious chemical substances

Engineering Contradiction:
Improveisolation effectivenessVSAvoidchemical exposure risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The isolation apparatus automatically adjusts and positions itself to accommodate different substrate diameters through the movement of segments along guiding track ways. This self-adjusting mechanism eliminates the need for manual mask handling, thereby protecting workers from exposure to noxious chemical substances while maintaining effective isolation.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If fixed masks are used for isolation, then the isolation region is well-defined, but the apparatus cannot accommodate substrates of varying diameters without mask changes

Engineering Contradiction:
Improveisolation region definitionVSAvoidsubstrate diameter range
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The isolation apparatus transitions from fixed masks to movable segments that can dynamically adjust their position along guiding track ways. This allows the isolation region to be precisely defined for each substrate while accommodating a wide range of substrate diameters, achieving both manufacturing precision and adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The apparatus achieves multi-functionality by using movable segments that can accommodate substrates of various diameters within a single device. The segments can be positioned to create isolation regions appropriate for different substrate sizes, eliminating the need for multiple fixed masks and enhancing versatility.

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

4Adaptability or versatility

If manual mask adjustment is used, then the isolation region can be adapted to substrate diameter, but the process is labor-intensive and time-consuming

Engineering Contradiction:
Improvesubstrate diameter adaptationVSAvoidadjustment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The isolation apparatus performs automatic adjustment of the isolation region to match substrate diameter through the movement of segments along guiding track ways. This self-adjusting capability eliminates manual intervention, significantly reducing adjustment time while maintaining adaptability to various substrate diameters.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The apparatus replaces manual mechanical adjustment with an automated mechanical system where segments are translocated along guiding track ways. This substitution of manual operation with automated mechanical movement reduces labor intensity and adjustment time while preserving substrate diameter adaptability.

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