Wall Bracket Sword with Displacement Path for Thermal Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall covering support devices face challenges in maintaining a uniform joint dimension across adjacent panels due to thermal expansion, leading to potential loud setting noises and instability, especially under varying temperature conditions.
Innovation Solution
A support device with a sword that can be releasably latched along a displacement path relative to the wall bracket, using latching means formed on the sword and insert, allowing for adjustable positioning and movement to compensate for length changes in panels and rails, thus avoiding noise and ensuring tension-free installation across the temperature range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the sword is permanently fixed in its reference position relative to the wall bracket, then the joint dimension uniformity is improved, but the device cannot compensate for thermal expansion and contraction of panels and rails
Solution Approach 1:
The sword is designed to be movable relative to the wall bracket along a defined displacement path, transitioning from a static fixed position to a dynamic adjustable position. This allows the sword to move and latch at different positions to compensate for thermal expansion and contraction of panels and rails while maintaining joint dimension uniformity through the reference position marking.
2Adaptability or versatility
If the sword is made displaceable relative to the wall bracket to compensate for thermal changes, then adaptability is improved, but loud setting noises occur during installation
Solution Approach 1:
Latching means are introduced as an intermediary mechanism between the sword and wall bracket. These latching means allow the sword to be securely held at specific positions (including the reference position) during installation, preventing unwanted movement that causes loud setting noises, while still allowing controlled displacement for thermal compensation when needed.
3Object-generated harmful factors
If the sword is made displaceable to avoid setting noises, then harmful factors are reduced, but the device loses stability and reliability
Solution Approach 1:
The connection between sword and wall bracket is designed with dynamic characteristics, allowing controlled movement along a defined displacement path while maintaining secure connection through latching means. This ensures the sword remains reliably positioned during normal use while accommodating thermal expansion and contraction without causing harmful noises.
4Adaptability or versatility
If latching means are added to enable releasable latching, then the reference position can be taken along the displacement path, but device complexity increases
Solution Approach 1:
The latching means are integrated into the existing sword and wall bracket structure, combining the latching function with the displacement mechanism. This approach enables releasable latching capability to allow the reference position to be taken along the displacement path while minimizing additional components and maintaining relatively simple device construction.
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 solution enables a uniform joint dimension and reduces noise during installation, ensuring the wall cladding remains free of tension across the entire temperature range by allowing the sword to move within defined displacement paths, and includes a securing element to prevent unintended movement or lifting.
Implementation Method 1
Wall coverings can be exposed to large temperature fluctuations, especially when used on the outside of a building. Depending on the material of the plates and/or the longitudinal rails, considerable changes in length sometimes occur.
