Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional fixed-angle connections are used to assemble picture frames from individual profiles, then the frame structure is simple and stable, but the design freedom and adaptability to various contours are limited

Engineering Contradiction:
Improvedesign freedomVSAvoidjoint arrangement complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The joint arrangement incorporates an adjustable angle mechanism that allows the connection between frame profiles to be dynamically changed. The angle adjustment feature enables the frame to adapt to various contours and shapes while maintaining structural integrity, resolving the contradiction between adaptability and complexity through a controlled dynamic system.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The joint arrangement is divided into separate functional components including the groove spring mechanism and the angle adjustment elements. This segmentation allows each component to perform its specific function independently, making the overall system more manageable and less complex while achieving the desired adaptability.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If fixed-angle corner connections are used in conventional picture frames, then the manufacturing process is simple, but customization for non-rectangular shapes requires costly and labor-intensive processes

Engineering Contradiction:
Improvecustomization effortVSAvoidshape flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The adjustable angle joint arrangement allows frame profiles to be connected at various angles without requiring specialized cutting tools or complex manufacturing processes. The dynamic angle adjustment capability enables easy customization for non-rectangular shapes while maintaining simple manufacturing procedures, effectively resolving the contradiction between ease of manufacture and shape flexibility.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If conventional picture frames are designed with parallel frame profiles, then the structure is stable and easy to manufacture, but the ability to adapt to complex geometries and contours is reduced

Engineering Contradiction:
Improvecontour adaptationVSAvoidframe stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The joint arrangement provides dynamic angle adjustment capability that allows the frame to adapt to complex geometries and contours. The groove spring mechanism maintains stable connection between profiles while enabling angle variation, thus achieving both contour adaptation and frame stability simultaneously.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The joint arrangement changes the connection angle parameter between frame profiles while maintaining the structural integrity. This parameter change capability allows the frame to adapt to various contours without compromising the stability of the overall composition.

Inventive Principle:
Principle #35Parameter changes
