Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If traditional rigid assembly methods are used for wall lining meshes, then structural stability is improved, but assembly complexity and difficulty increase

Engineering Contradiction:

Improvemesh stabilityVSAvoidassembly complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The mesh is divided into modular components (wefts and links) that can be independently manufactured and assembled. Each weft is a separate spiral element that connects to links at discrete points, allowing incremental assembly rather than requiring complete structure assembly at once.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The spiral wefts are designed to nest within the links during assembly. The wefts pass through and are contained by the links, creating a nested configuration where the flexible weft is held within the rigid link structure, providing both stability and ease of assembly.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If flexible wound meshes are used, then ease of transport and storage is improved, but assembly precision and structural integrity worsen

Engineering Contradiction:

Improveease of transportVSAvoidassembly precision

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The wefts are designed as flexible spiral elements that can dynamically adapt during assembly. They can be wound compactly for transport, then unwound and inserted into links during assembly, transitioning from a compact state to an assembled state while maintaining precision through the geometric constraints of the link structures.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The physical state of the wefts changes from wound/compact during transport to unwound/assembled during installation. The spiral geometry allows the same element to occupy different spatial configurations (wound vs. extended) while maintaining its structural function in both states.

Inventive Principle:

Principle #35Parameter changes

3Stability of the object's composition

If complex bending machinery is used to create zig-zag wefts, then mesh stability is improved, but manufacturing complexity and cost increase

Engineering Contradiction:

Improvemesh stabilityVSAvoidmanufacturing ease

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

Instead of bending rigid wefts into zig-zag shapes using complex machinery, the invention inverts the approach by using pre-formed spiral wefts that naturally achieve the required geometric configuration. The spiral shape is inherent to the weft manufacturing process rather than requiring post-forming bending operations.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The wefts are given a continuous spiral curvature rather than sharp zig-zag angles. This curved geometry is easier to manufacture using spiral forming processes and provides smooth stress distribution, eliminating the need for complex bending machinery required to create angular zig-zag shapes.

Inventive Principle:

Principle #14Spheroidality (Curvature)

4Adaptability or versatility

If spiral wefts with multiple peaks and valleys are used, then versatility in supporting accessories is improved, but link movement freedom decreases

Engineering Contradiction:

Improveaccessory support versatilityVSAvoidlink movement freedom

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The spiral weft has varying local geometries with peaks and valleys at different positions. Each peak-valley pair creates a localized connection point with links, allowing different regions of the mesh to support different types of accessories while maintaining overall structural consistency.

Inventive Principle:

Principle #3Local quality

AI summary

Wall lining mesh having a plurality of parallel wefts intended to be oriented preferably stacked at different levels and each extending over a length dimension; and a plurality of links connecting the wefts to one another. The wefts have a spiral shape wound around a notional core of revolution or a notional core having a polygonal cross-section, each weft having an alternating sequence of peaks and valleys with segments which extend in a direction having a component normal to the length dimension and which can pass through links, with each link surrounding a peak and a valley of different wefts.
