Solution Overview

Problem

Thin angle profiles used in thermal insulation composite systems face challenges in achieving sufficient rigidity for vertical installation while minimizing material usage and manufacturing costs, as they need to be thin to disappear into the plaster layer but require inherent rigidity to maintain stability.

Innovation Solution

The angle profile design features increased material thickness at the longitudinal corner edge and free longitudinal edge compared to adjacent areas, with a larger inner radius than outer radius, providing additional rigidity through targeted material thickenings and optimized radii ratios, allowing for reduced material usage without compromising stability.

1Quantity of substance

If the angle profile is made thin to disappear into the plaster layer, then the material usage and manufacturing costs are reduced, but the inherent rigidity and stability are insufficient for vertical installation

Engineering Contradiction:

Core Design Contradiction:
Quantity of substanceVSStrength

Solution Approach 1:

The angle profile features non-uniform wall thickness distribution, with thicker sections at the corner longitudinal edge and free longitudinal edges, and thinner sections in the adjoining areas. This local variation in material distribution provides enhanced rigidity at critical structural locations while minimizing overall material consumption, resolving the contradiction between thin profile design and sufficient structural strength.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The invention introduces a third dimension (wall thickness variation) to the otherwise two-dimensional profile design. By varying the wall thickness in the longitudinal direction, the profile achieves increased rigidity through strategic material placement without increasing the overall cross-sectional dimensions, allowing the profile to remain thin while disappearing into the plaster layer.

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

2Strength

If the material thickness is increased at the longitudinal corner edge, then the rigidity is improved, but the material consumption increases

Engineering Contradiction:
ImproverigidityVSAvoidmaterial consumption
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The angle profile implements localized thickening only at the corner longitudinal edge and free longitudinal edges where structural rigidity is most needed for vertical installation. The wall thickness returns to a thinner dimension in the adjoining profile leg areas, optimizing the balance between localized strength enhancement and overall material consumption reduction.

Principle #3Local quality

AI summary

The bracket (1) has two profile legs (2,3) each having outer surfaces (10,11) and inner surfaces (12,13), such that the outer and the inner surfaces are connected along corner longitudinal edge (6) of bracket main portion. The two outer surfaces of the profile legs are connected over an external connection portion (14), and the two inner faces of the profile legs are connected over an inner connection portion (15). The material thickness of the profile legs in the region of free longitudinal edges (4,5) is greater than thickness in the subsequent regions (8,9) of the profile leg.
