Solution Overview

Problem

Current panel systems for cladding surfaces, such as roofs and walls, face challenges in precise alignment and coupling due to complex profiles with undercuts, leading to deformation or damage during assembly and inadequate sealing against infiltrations.

Innovation Solution

The panel system features a complex profile with a first coupling having a curved head portion, an inclined base, and an intermediate arcuate portion that creates a temporary housing for correct alignment, along with a second coupling with a U-shaped profile and a longitudinal groove for water collection and drainage, facilitated by a fixing bracket for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If complex coupling profiles with undercuts are used to enable panel interlocking, then panel coupling strength is improved, but alignment precision deteriorates and risk of damage during assembly increases

Engineering Contradiction:
Improvepanel coupling strengthVSAvoidalignment precision
Core Design Contradiction:
StrengthVSManufacturing precision

Solution Approach 1:

The coupling profile is segmented into distinct functional zones: an insertion portion for initial engagement, an undercut portion for locking, and sealing portions for weather protection. This segmentation allows each zone to perform its specific function optimally without interfering with alignment precision during insertion.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A fixing bracket is introduced as an intermediary component between the panel coupling profiles and the support structure. The bracket provides precise positioning and alignment during assembly, eliminating the need for manual alignment of the complex coupled profiles while maintaining coupling strength.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Strength

If complex coupling profiles with undercuts are used to enable panel interlocking, then panel coupling strength is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvepanel coupling strengthVSAvoidease of coupling
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The coupling operation is segmented into distinct phases: insertion of the insertion portion, engagement of the undercut portion, and sealing through the sealing portions. This segmentation simplifies the operational sequence, allowing workers to perform each step systematically without struggling with the entire complex profile at once.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixing bracket serves as a mediator that holds panels in correct alignment during the coupling process, reducing the physical effort and skill required to align and connect the complex profiles. The bracket makes the coupling operation more accessible to workers with varying skill levels.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Strength

If complex coupling profiles are used for panel connection, then coupling strength is improved, but sealing performance against infiltrations deteriorates

Engineering Contradiction:
Improvecoupling strengthVSAvoidsealing performance
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

Different portions of the coupling profile are assigned different local qualities: the insertion portion has a geometry optimized for alignment, the undercut portion for mechanical locking, and dedicated sealing portions with weather-sealing properties. This local differentiation ensures that sealing performance is not compromised by the complexity of the overall profile.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The complex geometry of the coupling profile, which initially appears to create gaps and infiltration paths, is redesigned so that the same geometric features that provide mechanical strength also create overlapping relationships between adjacent panels. These overlaps, when combined with sealing portions, actually enhance weather protection by creating multiple barriers against water infiltration.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Strength

If pressure is exerted to complete the coupling of panels, then coupling strength is improved, but risk of deformation or damage to profiles increases

Engineering Contradiction:
Improvecoupling strengthVSAvoidprofile integrity
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The force application is segmented and distributed: the fixing bracket provides initial alignment and distributes positioning forces, while the panel coupling profiles engage in a controlled sequence. This segmentation of force application prevents concentrated loads that could deform or damage the profiles during assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fixing bracket and the geometric design of the coupling profiles provide built-in cushioning mechanisms that absorb and distribute assembly forces. The bracket acts as a buffer that prevents excessive or misaligned forces from being transmitted directly to the coupling profiles, thereby protecting them from deformation or damage.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
