Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If traditional oil hydraulic press structure is used, then structural stability is ensured, but device complexity and material consumption increase

Engineering Contradiction:
Improvestructure complexityVSAvoidstructural stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The support frame is divided into multiple buckle frames (first buckle frames and second buckle frames) that are symmetrically arranged and connected. Each buckle frame segment independently supports the main cylinder assembly and fixed die tables, allowing the structure to maintain stability while reducing overall complexity and material consumption compared to a monolithic frame design.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If traditional oil hydraulic press structure is used, then structural stability is ensured, but manufacturing cost increases

Engineering Contradiction:
Improvemanufacturing costVSAvoidstructural stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The support frame is segmented into multiple buckle frames that can be manufactured separately and assembled, reducing manufacturing cost while maintaining structural stability. The symmetric arrangement of these segments allows for standardized production and reduced material consumption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The buckle frames are symmetrically connected to form a unified support structure that integrates multiple functions (support, stability, guidance) into a single assembled unit, reducing the need for additional components and lowering overall manufacturing cost.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If traditional oil hydraulic press structure is used, then pressing capability is maintained, but production flexibility is limited

Engineering Contradiction:
Improveproduction flexibilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The segmented buckle frame structure allows for modular configuration where main cylinder assemblies and fixed die tables can be arranged in different patterns (single set, dual sets, or multiple sets in parallel) while maintaining structural integrity, thereby enhancing production flexibility without significantly increasing complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The symmetric buckle frames serve multiple functions: supporting main cylinder assemblies, mounting fixed die tables, providing structural stability, and guiding piston movement. This multi-functionality allows the same basic structure to accommodate various production configurations, improving adaptability.

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

AI summary

The present disclosure provides an oil hydraulic press including a support frame, at least one main cylinder assembly and at least one fixed die table. The at least one main cylinder assembly includes a cylinder body and a piston connected to the cylinder body, the support frame includes two sets of end frames, the cylinder body is located between the two sets of end frames. Each of the two sets of end frames includes two first buckle frames, and the two first buckle frames are symmetrically arranged around a moving shaft of the piston, one end of each of the two first buckle frames carries the cylinder body, and the other end of each of the two first buckle frames carries the fixed die table. And a pressing mechanism is formed between the piston and the fixed die table. The oil hydraulic press in the present disclosure has following advantages. The main cylinder assembly and the fixed die table can be fixed by the support frame, which forms a ring-like structure, can be operated in one, two or multiple sets in parallel, and all can realize pressing manufacture. The oil hydraulic press has less components, reduced material consumption and low manufacturing cost.
