Resilient Mounting Clips for Panel Expansion and Contraction

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Structural panels made of materials like wood, which expand and contract due to temperature and moisture changes, can shift and exert forces that compromise the integrity of structural surfaces such as rain screens and decks, as existing fastening systems fail to accommodate these changes effectively.

Innovation Solution

Resilient mounting clips with edge extensions and outboard panel supports that flex to accommodate panel expansion and contraction, securely retaining panels relative to a support structure while allowing for movement along a compression axis, thereby maintaining structural integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rigid fastening systems are used to securely attach panels, then panel retention is improved, but panel shifting due to expansion and contraction cannot be accommodated

Engineering Contradiction:

Improvepanel retentionVSAvoidaccommodation of panel movement

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The mounting clip incorporates resilient elements that enable dynamic adjustment to accommodate panel expansion and contraction while maintaining secure retention. The resilient portion allows the clip to flex and adapt to panel movement, transforming a static fastening system into a dynamic one that responds to environmental changes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The mounting clip changes its physical parameters (position, shape) through resilient flexing to accommodate panel movement. The resilient portion undergoes elastic deformation, changing its geometric parameters to absorb expansion forces while maintaining connection integrity.

Inventive Principle:

Principle #35Parameter changes

2Strength

If panels are positioned in close proximity to provide barriers, then structural integrity is improved, but expansion forces between panels increase

Engineering Contradiction:

Improvestructural integrityVSAvoidexpansion forces

Core Design Contradiction:

StrengthVSForce

Solution Approach 1:

The mounting clip acts as an intermediary element between adjacent panels, absorbing and managing expansion forces. The resilient portion serves as a buffer that mediates the interaction between panels, allowing them to remain in close proximity while accommodating thermal and moisture-induced expansion.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The resilient portion of the mounting clip provides beforehand cushioning by being pre-configured to absorb expansion forces. This cushioning effect is built into the fastening system, allowing it to handle expansion forces before they can compromise the structural integrity of closely positioned panels.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Ease of manufacture

If non-resilient mounting clips are used, then manufacturing simplicity is improved, but accommodation of environmental changes is lost

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidaccommodation of expansion and contraction

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The mounting clip incorporates a resilient portion that functions as a flexible element, allowing the otherwise simple structure to accommodate environmental changes. This flexible component can be integrated into conventional manufacturing processes while adding the necessary adaptability to handle panel expansion and contraction.

Inventive Principle:

Principle #30Flexible shells and thin films
