Solution Overview

Problem

Existing building panels face challenges in smoothly fitting and easily removing and refitting tensioned textiles or foils at corners, especially when dealing with varying thicknesses, which often require cutting and gluing, making reusability after washing difficult.

Innovation Solution

The building panel incorporates a resilient member attached to the corner, forming an internal cavity that retains excess textile or foil at either side of the slot, allowing for smooth fitting and easy removal by pinching or channeling, with optional cover plates for enhanced holding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If excess textile is inserted into a groove at the corner and retained by a resilient member, then the textile can be easily removed and refitted after washing, but the corner structure becomes more complex requiring additional components

Engineering Contradiction:
Improveease of removal and refittingVSAvoidcorner structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The corner structure is divided into separate functional components: a groove for receiving excess textile, a resilient member for retaining the textile, and an optional cover plate for finishing. This segmentation allows each component to perform its specific function independently, making the overall system easier to manufacture and assemble while providing the desired ease of removal and refitting

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The resilient member provides dynamic retention capability, allowing the textile to be easily inserted and removed by deforming the resilient member temporarily. This dynamic characteristic enables repeated use and refitting after washing without permanent damage or complex disassembly procedures

Inventive Principle:
Principle #15Dynamics

2Shape

If the textile is cut to fit exactly at the corner, then the appearance is neat and smooth, but the textile cannot be remounted after washing

Engineering Contradiction:
Improvesmooth finish at cornerVSAvoidreusability after washing
Core Design Contradiction:
ShapeVSAdaptability or versatility

Solution Approach 1:

Instead of cutting the textile to fit exactly at the corner, the invention intentionally leaves excess textile that extends into the corner groove. This excessive action ensures that the textile can be removed, washed, and refitted multiple times while still maintaining a neat appearance when properly installed, thus prioritizing reusability while achieving acceptable aesthetic results

Inventive Principle:
Principle #16Partial or excessive action

3Ease of operation

If a resilient member is added to retain excess textile in the groove, then the textile can be temporarily held during fitting, but the manufacturing process becomes more complex

Engineering Contradiction:
Improveease of fitting during installationVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The resilient member is designed to be self-retaining within the corner structure, utilizing the groove geometry and its own elastic properties to hold the textile in place during fitting operations. This self-service characteristic reduces the need for additional fastening operations or complex assembly procedures, thereby minimizing the impact on manufacturing complexity while significantly improving ease of fitting

Inventive Principle:
Principle #25Self-service

AI summary

A textile or foil is extended between frame profile members (6) and edges thereof are fixed to a building-facing side of the frame profile members. Neighbouring frame profile members are connected at corners of the panel (1). Each corner has a slot (13) formed between opposed parts of the corner and extending at an oblique angle in relation to each one of the neighbouring frame profile members. Each corner forms an internal cavity extending laterally from either side of the slot of the corner behind opposed wall parts (18, 19) of the corner arranged at either side of the slot. A resilient member (16) is attached to the corner and extends at either side of the slot in the internal cavity of the corner of the panel, and the resilient member is adapted to retain excess textile at either side of the slot in the internal cavity of the corner.
