Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a conventional frame structure is used to secure rigidity, then structural strength is improved, but structural design flexibility is restricted and deformation occurs during assembly/disassembly

Engineering Contradiction:
Improvestructural strengthVSAvoidstructural design flexibility
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The frame is divided into multiple modular units (first frame unit, second frame unit, third frame unit, fourth frame unit) that can be independently assembled and disassembled. Each frame unit includes separate components (side plates, cross plates, reinforcing plates) that can be configured flexibly while maintaining overall structural strength through the interconnected modular architecture.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If conventional assembly methods are used, then assembly is straightforward, but deformation occurs during the assembling/dissembling process and screw-thread wear defects are caused

Engineering Contradiction:
Improveassembly straightforwardnessVSAvoiddeformation control
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

Reinforcing plates are pre-installed on the frame units before final assembly. These reinforcing plates include positioning structures (protrusions and corresponding recesses) that are prepared in advance to guide and constrain the assembly process, preventing deformation during assembly/disassembly operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Reinforcing plates serve as intermediary components between the side plates and cross plates. They include positioning structures that mediate the connection, distributing mechanical stresses and preventing direct contact that would cause deformation and screw-thread wear.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Strength

If multiple screws are used for assembly, then connection strength is improved, but screw-thread wear defects occur and assembly efficiency is reduced

Engineering Contradiction:
Improveconnection strengthVSAvoidassembly efficiency
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The reinforcing plates include positioning structures (protrusions fitting into recesses) that enable self-aligning and self-constraining during assembly. This self-service mechanism reduces the need for multiple adjustment operations and minimizes screw-thread wear by ensuring proper alignment before fastening, thereby improving assembly efficiency while maintaining connection strength.

Inventive Principle:
Principle #25Self-service
