Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If secondary cylinders are arranged at both ends of the primary cylinder, then cleaning capability is improved, but device size and cost increase

Engineering Contradiction:

Improvecleaning capabilityVSAvoiddevice size

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The invention extracts the cleaning function from a separate secondary cylinder system and integrates it into the primary cylinder through a cleaning hole and cleaning liquid supply mechanism. This eliminates the need for additional secondary cylinders while maintaining cleaning capability, thereby reducing device size and cost.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The primary cylinder is designed to serve multiple functions: pressurizing the raw material and cleaning the interior. By incorporating a cleaning hole and cleaning liquid supply mechanism directly into the primary cylinder, the system achieves multi-functionality without requiring separate dedicated cleaning components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of manufacture

If conventional intensifier structure is used, then manufacturing simplicity is maintained, but cleaning capability without disassembly is lost

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidcleaning capability without disassembly

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The invention segments the cleaning function from the pressurization function by providing a separate cleaning hole and cleaning liquid supply mechanism within the primary cylinder. This allows cleaning operations to be performed independently without disassembling the entire intensifier, maintaining manufacturing simplicity while enabling easy cleaning.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention introduces a cleaning liquid as an intermediary medium to facilitate cleaning without disassembly. The cleaning liquid is supplied through dedicated channels and flows through the primary cylinder interior, enabling effective cleaning while maintaining the structural integrity and simplicity of the intensifier design.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If gaps exist during plunger sliding, then ease of operation is improved, but raw material adhesion and contamination increase

Engineering Contradiction:

Improveplunger sliding easeVSAvoidraw material adhesion

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The invention performs preliminary cleaning action by continuously supplying cleaning liquid to the primary cylinder interior during operation. This prevents raw material from adhering to surfaces in the first place, addressing the adhesion problem before it occurs while maintaining smooth plunger sliding through the cleaning liquid film.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention converts the potentially harmful effect of gaps during plunger sliding into a beneficial cleaning mechanism. The cleaning liquid supplied through the cleaning hole flows through the gaps and along the plunger surface, transforming what would be a contamination zone into an effective cleaning pathway that prevents adhesion while maintaining operational ease.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
