Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If traditional linear or flat structures are used for foldable brackets, then the structure is simple, but the lateral space occupied in the folded state remains large

Engineering Contradiction:
Improvestructure simplicityVSAvoidlateral space in folded state
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The patent transitions from traditional linear/flat folding structures to a multi-dimensional folding mechanism where support rods and crossbars fold along multiple axes simultaneously. The support post integrates vertical and lateral folding movements, allowing the bracket to collapse into a compact three-dimensional configuration that minimizes lateral space occupation while maintaining structural integrity through spatial arrangement of folding components.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If the bracket structure is made complicated to ensure supporting performance, then the supporting stability is improved, but the volume in the folded state increases

Engineering Contradiction:
Improvesupporting stabilityVSAvoidvolume in folded state
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent implements a nested folding configuration where smaller structural components are positioned within the spatial envelope of larger components during the folded state. The support crossbars nest within the space defined by the support rods, and secondary support elements are arranged within the volumetric boundaries of primary structural members, achieving compact packaging while maintaining the necessary structural complexity for supporting stability when deployed.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If the bracket is designed for easy folding to reduce volume, then the portability is improved, but the supporting performance may be compromised

Engineering Contradiction:
Improvefolding convenienceVSAvoidsupporting performance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent employs dynamic folding mechanisms with multiple rotatable joints and connecting members that enable smooth transitions between deployed and folded states. The support post incorporates telescopic sections and rotating connections that allow the bracket to adapt its configuration dynamically, maintaining structural integrity during folding operations while ensuring stable supporting performance when deployed through engineered joint geometries and connection mechanisms.
