Solution Overview

Problem

Existing cladding support systems are cumbersome and time-consuming to install and remove, and they often lack load-bearing functionality due to misalignment of teeth, which can cause vibration and noise.

Innovation Solution

A profile fixing accessory with a lock element and key element, featuring a flexible link allowing relative movement in the Y-direction and a wedge to limit movement in the X-direction, ensuring secure locking and alignment with elongated profiles having sawtooth or triangular toothed edges, facilitating easy installation and de-installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If asymmetric teeth are used to allow easy movement in one direction, then installation speed is improved, but misalignment occurs due to production tolerances leading to vibration and noise

Engineering Contradiction:
Improveinstallation speedVSAvoidalignment precision
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The lock element incorporates a flexible link that enables dynamic adjustment of the toothed sections. This flexibility allows the sections to adapt to manufacturing tolerances and achieve proper alignment with the profile groove, eliminating the vibration and noise problems while maintaining easy installation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the rigidity parameter of the connection between toothed sections by introducing a flexible link. This allows the system to transition from a rigid misaligned state to a flexible aligned state, resolving the contradiction between easy installation and precise alignment.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If teeth are made wide to accommodate misalignment, then alignment tolerance is improved, but load-bearing capacity decreases due to reduced contact surface

Engineering Contradiction:
Improvealignment toleranceVSAvoidload-bearing capacity
Core Design Contradiction:
Manufacturing precisionVSStrength

Solution Approach 1:

The flexible link enables the toothed sections to dynamically adjust their positions to achieve alignment without requiring wide teeth. This dynamic adaptation maintains the full contact surface area, preserving load-bearing capacity while accommodating manufacturing tolerances.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If friction-based movement is used to reposition the accessory, then no screws are needed, but the movement becomes cumbersome and time-consuming

Engineering Contradiction:
Improvefixing mechanism simplicityVSAvoidrepositioning ease
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The flexible link creates a ratcheting mechanism that allows easy forward movement (installation) while preventing backward movement (removal). This dynamic behavior provides both simplicity and ease of operation, as the accessory can be quickly installed by overcoming friction in one direction but cannot be accidentally removed.

Inventive Principle:
Principle #15Dynamics

4Productivity

If the profile fixing accessory is made movable for easy installation, then installation speed is improved, but load-bearing functionality is compromised

Engineering Contradiction:
Improveinstallation speedVSAvoidload-bearing functionality
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The system transitions from a movable state during installation to a locked immovable state during use. The flexible link enables easy installation through controlled movement, while the wedge mechanism and toothed engagement provide rigid load-bearing capacity once installed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The wedge mechanism automatically locks the toothed sections in place once the accessory is installed, providing self-reinforcing load-bearing functionality without requiring additional fasteners. The system serves itself by converting installation movement into locking force.

Inventive Principle:
Principle #25Self-service
