Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electrodes are fixed permanently in the PEF chamber, then electrical connection stability is improved, but electrode replacement and maintenance become difficult

Engineering Contradiction:
Improveelectrical connection stabilityVSAvoidelectrode replacement difficulty
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The electrode system is divided into separate electrode units that can be independently inserted into and removed from the PEF chamber. Each electrode unit includes an electrode element with insulation coating and connection elements, allowing modular replacement while maintaining stable electrical connections through dedicated connection structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The electrode units are designed with dynamic insertion and removal capabilities through threaded connections or gripping mechanisms. This allows the electrodes to be fixed securely during operation for stable electrical connection, yet easily removed for replacement or maintenance when needed.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If the PEF chamber is designed as a sealed integrated unit, then pressure stability is improved, but electrode access and replacement become difficult

Engineering Contradiction:
Improvepressure stabilityVSAvoidelectrode access difficulty
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The PEF chamber is designed as an integrated sealed unit for pressure stability, while the electrode units are segmented as separate insertable components. This allows the chamber to maintain pressure stability during operation while enabling easy access to electrodes through the insertion/removal mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Connection elements and fixation mechanisms serve as intermediaries between the sealed chamber structure and the electrode units. These intermediaries allow electrodes to be securely fixed during operation for pressure stability, yet easily removed for access and replacement.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If complex fixation mechanisms are used for electrodes, then electrode security is improved, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The fixation function is segmented into simple, standardized connection elements that are integrated into the electrode units themselves. These connection elements provide secure fixation through straightforward mechanisms like threading or gripping, avoiding complex external fixation systems while maintaining electrode security.

Inventive Principle:
