Solution Overview

Problem

Existing cladding systems face challenges in providing a secure, aesthetically pleasing, and easily accessible solution for covering elements in moving spaces, as they often compromise between mechanical strength and ease of access, with concealed fastening points being either difficult to reposition or lacking in mechanical resilience.

Innovation Solution

A cladding system featuring a non-contact locking mechanism that ensures reliable repositioning and attachment of cladding elements to a support structure, with concealed fastening points and a positioning device for precise lateral positioning, allowing for easy access and maintenance without compromising mechanical strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If cladding elements are attached with concealed screws or nails using a tongue and groove system, then mechanical load capacity is improved, but ease of access to points behind paneling deteriorates

Engineering Contradiction:
Improvemechanical load capacityVSAvoidease of access to points behind paneling
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The cladding system is divided into individually detachable cladding elements that can be removed separately from the support structure. Each element can be accessed and detached independently, allowing maintenance personnel to reach points behind the paneling without removing entire sections, thus resolving the contradiction between mechanical strength and ease of access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fastening mechanism is extracted from the visible surface and concealed within the cladding element structure. The fastening points are hidden from the visible side while maintaining secure attachment, allowing both aesthetic appearance and mechanical strength to coexist while enabling individual element removal for access.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If cladding elements are attached individually with non-positive fit fasteners, then ease of access to points behind paneling is improved, but manufacturing precision deteriorates

Engineering Contradiction:
Improveease of access to points behind panelingVSAvoidrepositioning precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The traditional mechanical fastening system is replaced with a magnetic locking mechanism. Magnets provide secure attachment while allowing easy individual removal and precise repositioning of cladding elements. The magnetic field enables both ease of access for maintenance and high repositioning precision, resolving the contradiction between operational ease and manufacturing precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If cladding elements are attached with snap fasteners, then ease of access to points behind paneling is improved, but reliability deteriorates

Engineering Contradiction:
Improveease of access to points behind panelingVSAvoidmechanical resilience
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Mechanical snap fasteners are replaced with a magnetic locking system combined with individual detachable elements. The magnetic attraction provides consistent and reliable holding force that does not degrade with repeated attachment and detachment cycles, while still allowing easy individual element removal for maintenance access, thus resolving the contradiction between operational ease and reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
