Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing drywall constructions with vertical upright profiles are labor-intensive and costly to adapt for installation elements like shelves and cupboards, as they require individual customization and lack a standard mounting system, leading to instability and difficulties in achieving precise alignment and sealing.

Innovation Solution

The use of installation elements with grooves on their outer surfaces and a bracket-like holder system that clamps onto the upright profiles, allowing for easy alignment, secure fastening, and stiffening of the profiles, while enabling precise positioning and adjustment without damaging the reinforcement sheet during surface grinding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If individual openings are paneled with gypsum plaster boards, then the drywall construction can accommodate installation elements, but the edges require additional edge protection and costly additional structures to secure the boards

Engineering Contradiction:

Improveadaptability to installation elementsVSAvoidcomplexity of additional structures

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The upright profile is segmented into functional zones: the C-shaped cross section with legs provides structural support, while the legs extend into the hollow space to engage with installation elements. This segmentation allows the profile to serve multiple functions without additional structures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The upright profile with C-shaped cross section and legs serves multiple functions simultaneously: structural support for drywall panels, mounting support for installation elements, and stabilization of the hollow space. This eliminates the need for separate edge protection and securing structures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If installation elements are individually adapted to building circumstances, then they can fit specific requirements, but the process becomes labor and cost intensive

Engineering Contradiction:

Improveadaptability to building circumstancesVSAvoidinstallation efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The upright profiles are pre-fabricated with C-shaped cross sections and integrated legs during manufacturing. This preliminary action allows installation elements to be quickly mounted without on-site customization, significantly improving installation efficiency while maintaining adaptability.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If upright profiles are used without paneling on both sides, then one-sided paneling is possible, but the profiles become unstable especially with multiple installation elements

Engineering Contradiction:

Improveflexibility of paneling configurationVSAvoidstability of upright profiles

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The C-shaped cross section with legs is pre-formed during manufacturing to provide inherent structural stability. This preliminary structural design allows the profiles to remain stable even with one-sided paneling or multiple installation elements, as the geometry itself provides rigidity.

Inventive Principle:

Principle #10Preliminary action

4Reliability

If installation elements are screwed onto upright profiles, then they are securely fastened, but re-orientation requires complete dismantling and screw holes become disturbances

Engineering Contradiction:

Improvesecure fasteningVSAvoidease of re-orientation

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The mounting function is extracted from the upright profile by using the legs extending into the hollow space. Installation elements can be mounted on these legs without screwing into the profile itself, allowing easy removal and re-orientation without creating permanent screw holes in the visible profile surface.

Inventive Principle:

Principle #2Taking out (Extraction)

5Reliability

If screws are used to fasten installation elements onto thin steel plate webs, then fastening is achieved, but the tension force deforms the web and the flat bearing surface of the legs

Engineering Contradiction:

Improvefastening strengthVSAvoiddeformation of web and bearing surface

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The load path is segmented: the C-shaped profile provides structural support, while the legs extending into the hollow space provide the mounting surface. This segmentation distributes the load, preventing deformation of the thin web and bearing surface by transferring forces to the more robust leg structures.

Inventive Principle:

Principle #1Segmentation
