Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If rigid strips of fixed size are used in a grid pattern, then structural stability is improved, but adaptability to different substructures and flexible installation is worsened

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability to different substructures
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The spacer element is divided into multiple individual blocks connected by webs, forming a modular structure. This segmentation allows the spacer to maintain structural stability through the rigid blocks while enabling flexibility and adaptability through the elastic webs that can deform to accommodate different substructure configurations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spacer element incorporates elastic webs that allow dynamic deformation. The webs can stretch and bend to adapt the spacer element to various substructure widths and configurations, transforming a static rigid structure into a dynamic adaptive one that maintains stability while accommodating different installation scenarios.

Inventive Principle:
Principle #15Dynamics

2Stability of the object's composition

If solid continuous material is used for the spacer, then structural stability is improved, but water drainage and air circulation are worsened

Engineering Contradiction:
Improvestructural stabilityVSAvoidwater drainage and air circulation
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The spacer element employs a porous-like structure with gaps between individual blocks and openings within the web connections. This allows water to drain through and air to circulate while the overall structure maintains structural stability through the rigid blocks and connecting webs.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

By segmenting the continuous material into discrete blocks with spacing between them, the structure maintains stability through the blocks while creating channels for water drainage and air circulation through the gaps and web openings.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If the spacer element is made as a single rigid piece, then manufacturing precision is improved, but ease of operation and flexible installation are worsened

Engineering Contradiction:
Improvemanufacturing precisionVSAvoidflexible installation
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The spacer element is manufactured as an integrated piece with segmented blocks and webs, achieving manufacturing precision through single-piece production while the segmented design provides flexibility for installation. The elastic webs allow the structure to be bent and adapted to different configurations without requiring assembly of separate components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spacer element utilizes material parameter changes, specifically the elastic properties of the webs, to enable flexible installation. The webs can deform elastically to accommodate different installation scenarios while the overall structure remains a precisely manufactured single piece.

Inventive Principle:
Principle #35Parameter changes

4Loss of substance

If the web connecting blocks is made narrow to save material, then material efficiency is improved, but structural stability in lateral direction is worsened

Engineering Contradiction:
Improvematerial efficiencyVSAvoidlateral stability of strand
Core Design Contradiction:
Loss of substanceVSStability of the object's composition

Solution Approach 1:

The web's elastic properties are optimized to provide sufficient lateral stability despite its narrow cross-section. The material parameters of the web are selected to ensure it can resist lateral forces while minimizing material usage, achieving a balance between material efficiency and structural stability.

Inventive Principle:
Principle #35Parameter changes

AI summary

A spacer element is modularly constructed from a multitude of individual sections (1) arranged one behind the other and connected to each other at joint points. Each section contains a multitude of equally sized spacer blocks (4) that have two end faces, the distance between which forms the distance to be maintained by the spacer element. The spacer blocks are connected to each other by a narrow web (5).
