Solution Overview

Problem

End profiles with insertion legs tend to wobble and slip during installation due to their flat design not matching the gap width, requiring additional effort for secure fastening like screwing or gluing.

Innovation Solution

Incorporating a resilient lip on the insertion leg that protrudes from one flat side, providing a spring effect to press against both the insulation element and the building structure, preventing wobbling and slipping without separate fasteners, and allowing sealing of gaps of varying widths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the insertion leg is designed with a flat shape for simple installation, then the ease of manufacture is improved, but the stability and positioning accuracy deteriorate because the flat insertion leg cannot reliably hold the end profile in position and tends to wobble and slip

Engineering Contradiction:
Improveease of manufactureVSAvoidpositioning stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The insertion leg is designed with a resilient lip that can elastically deform during insertion. The lip bends when pressed against the insulation element and building structure, then springs back to provide continuous contact pressure that prevents wobbling and slipping, transforming a static flat structure into a dynamic self-adjusting component

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The resilient lip changes the physical state of the insertion leg from rigid to elastically deformable. By introducing elastic deformation as a parameter change, the insertion leg can adapt to varying gap widths while maintaining stable contact, resolving the contradiction between simple flat design and positioning stability

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the insertion leg is made shallower than the gap width for easy insertion, then the ease of operation is improved, but the reliability deteriorates because the end profile cannot be securely held and requires additional fastening methods

Engineering Contradiction:
Improveease of insertionVSAvoidsecuring reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The resilient lip enables the insertion leg to self-adjust and self-secure within the gap. As the lip is pressed against the insulation element and building structure, it elastically deforms and springs back to provide continuous contact pressure, allowing the end profile to self-hold without requiring separate fasteners, thus achieving both easy insertion and reliable securing

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The resilient lip introduces dynamic elastic deformation that allows the insertion leg to adapt to the gap dimensions during insertion, then maintain secure holding through continuous spring pressure, eliminating the need for additional fastening operations

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If a resilient lip is added to the insertion leg to improve positioning stability, then the positioning accuracy is improved, but the device complexity increases due to the additional component

Engineering Contradiction:
Improvepositioning accuracyVSAvoidstructural complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The resilient lip is designed as a segmented or integrated feature of the insertion leg rather than a completely separate component. This segmentation approach allows the lip to be molded directly onto the insertion leg or formed as an integral part, adding the necessary elastic functionality while minimizing overall structural complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The resilient lip is merged with the insertion leg to form an integrated elastic structure. By combining the lip and insertion leg into a single elastic component, the design achieves improved positioning accuracy without the complexity of multiple separate parts, as the lip becomes an inherent feature of the insertion leg itself

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The resilient lip effectively holds the end profile in position and seals gaps, preventing moisture entry, without the need for additional fastening, ensuring a reliable and moisture-tight installation.

Implementation Method 1

at least one resilient lip is arranged on the insertion leg, which protrudes from one of the flat sides and extends in the longitudinal direction. Due to its spring action, the lip presses the insertion leg against the insulation element, thus holding the end profile in position.

AI summary

An end profile for insulation elements has a profile body extending in a longitudinal direction, which includes an insertion leg. The insertion leg is designed for insertion between an insulation element and an adjacent building component, in particular a floor surface, and has two flat sides that are opposite each other such that, when the insertion leg is inserted, one of the flat sides faces the insulation element and the other flat side faces the building component. At least one resilient lip is arranged on the insertion leg, projecting from one of the flat sides and extending in the longitudinal direction.
