Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a driving mechanism is used to change curvature, then curvature adjustment capability is improved, but stability of the driving mechanism deteriorates

Engineering Contradiction:
Improvecurvature adjustment capabilityVSAvoidstability of driving mechanism
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent employs a dynamic mechanism where a lead screw rotates to move a slider linearly, which in turn causes wings to pivot and change the curvature of the flexible display panel. This dynamic system allows continuous curvature adjustment while maintaining stability through controlled mechanical motion rather than fixed structural changes

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The driving mechanism is segmented into independent functional components: a lead screw for rotational motion, a slider for linear motion, and wings with pivot shafts for angular adjustment. This segmentation allows each component to perform its specific function optimally while contributing to overall system stability through modular design

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a driving mechanism is used to change curvature, then curvature adjustment capability is improved, but noise and vibrations generated during driving increase

Engineering Contradiction:
Improvecurvature adjustment capabilityVSAvoidnoise and vibrations
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent introduces elastic members as intermediary elements between the mechanical driving components and the flexible display panel. These elastic members act as buffers that absorb vibrations and reduce noise generated during the curvature adjustment process, while still transmitting the necessary mechanical force to achieve the desired curvature change

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If elastic members are used to connect components, then stability of driving mechanism is improved, but device complexity increases

Engineering Contradiction:
Improvestability of driving mechanismVSAvoiddevice complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent uses elastic members that function as flexible connecting elements between the rigid mechanical components (lead screw, slider, wings) and the flexible display panel. These elastic members provide necessary compliance and vibration damping while maintaining a relatively simple overall structure, avoiding the need for complex suspension or isolation systems

Inventive Principle:
Principle #30Flexible shells and thin films
