Solution Overview

Problem

Existing bar systems for building constructions face challenges in cost-efficiency and durability due to breakage of engagement means during transportation and assembly, and require larger level adjustment means that interfere with insulation space, affecting both mechanical and acoustic dampening.

Innovation Solution

The design features engagement means that press towards the level adjustment means, enclose them, and use through recesses for snap fastening, allowing for stronger and more robust connections, reduced material consumption, and efficient assembly, while the level adjustment means are integrated into the bars to minimize vertical extension and protect against breakage during transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If engagement means are pressed away from the level adjustment means during assembly, then assembly is simpler, but the engagement means are weaker and more prone to breaking

Engineering Contradiction:

Improveassembly simplicityVSAvoidengagement means strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The engagement means are designed to press towards the level adjustment means instead of away from it. This inverted direction creates a larger joint area between the engagement means and the level adjustment means, resulting in stronger connections that are less prone to breaking during assembly and transportation.

Inventive Principle:

Principle #13The other way round (Inversion)

2Stability of the object's composition

If level adjustment means have larger extension to ensure stability, then stability is improved, but they interfere with insulation space and increase material consumption

Engineering Contradiction:

Improvelevel adjustment stabilityVSAvoidmaterial consumption

Core Design Contradiction:

Stability of the object's compositionVSLoss of substance

Solution Approach 1:

By inverting the direction of the engagement means to press towards the level adjustment means, the level adjustment means can achieve stable engagement with a smaller extension. This eliminates the need for large protruding elements, thereby preserving insulation space and reducing material consumption.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of manufacture

If engagement means are designed to be pressed away from level adjustment means, then manufacturing is easier, but they break more frequently during transport and assembly

Engineering Contradiction:

Improveengagement means manufacturingVSAvoidengagement means durability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The engagement means are designed to press towards the level adjustment means, creating a larger joint area that enhances structural integrity. This inverted design makes the engagement means more robust and less susceptible to breaking during transportation and assembly operations.

Inventive Principle:

Principle #13The other way round (Inversion)

4Reliability

If level adjustment means extend further to ensure proper engagement, then engagement reliability is improved, but they interfere with insulation material placement

Engineering Contradiction:

Improveengagement reliabilityVSAvoidinsulation space

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

By reversing the engagement direction to press towards the level adjustment means, the system achieves reliable engagement without requiring the level adjustment means to extend further outward. This preserves the space needed for insulation material placement while maintaining engagement reliability.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

The present invention relates to a bar system (1) for building constructions, comprising bars (2), level adjustment means (29), and dampening means (18), each of said bars (2) comprising a recess positioned in a shank of said bars (2). Said bars (2) being adapted in use to at least partly enclose the level adjustment means (29), said level adjustment means (29) comprising level adjustable projections (11 ), being adapted to project from the bars (2) against a support structure (26). Said level adjustment means (29) being provided with a surface which extends in a longitudinal direction of the bars (2), as seen in the use of the system, and with engagement means adapted for engagement with said recess. The shank, which comprises the recesses that is adapted to engage with the engagement means, is adapted to press said engagement means towards said level adjustment means (29) during application of the bars (2) to the level adjustment means (29), and said recess is adapted to allow the engagement means for moving resiliently back for engagement with said recess in an interconnected position. The dampening means (18) extends in a longitudinal direction of the bars (2), as seen in the use of the system, and said surface of the level adjustment means (29) is adapted to support the dampening means (18).
