Insulation Retainer Clip With Drainage Gap for Rainscreen Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to retain insulation in place during wall construction while also creating a gap between the insulation and exterior cladding for water drainage, which is essential for a rainscreen type wall.
Innovation Solution
A clip designed to be snapped onto girts, featuring multiple walls that create slots to hold insulation in place and form channels between the insulation and exterior cladding, allowing for air and moisture drainage, without interfering with cladding installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a retainer clip is used to hold insulation in place, then insulation retention is improved, but no drainage gap is created between insulation and cladding
Solution Approach 1:
The retainer clip is segmented into multiple functional walls: an outer wall for retention, and additional walls (second, fourth, sixth, eighth walls) that extend to create drainage slots. This segmentation allows the single clip to simultaneously perform both insulation retention and water drainage functions without requiring separate components.
Solution Approach 2:
The retainer clip is designed as a multi-functional component that simultaneously: (1) retains insulation in place against the girt, (2) creates drainage slots/gaps between insulation and cladding, and (3) maintains structural integrity during construction. This eliminates the need for separate retention and drainage systems.
2Object-affected harmful factors
If multiple walls are added to create drainage slots, then water drainage capability is improved, but device complexity increases
Solution Approach 1:
Multiple functional elements (retention wall, drainage creation walls, slot-forming structures) are merged into a single integrated retainer clip component. This consolidation achieves complex functionality while avoiding the need for multiple separate parts, fasteners, or assembly steps that would increase overall system complexity.
Solution Approach 2:
The retainer clip utilizes thin-walled structural elements that can form multiple slots and drainage paths without requiring thick or bulky materials. The thin-walled design maintains structural adequacy while creating the necessary drainage geometry through the wall configurations themselves.
3Object-affected harmful factors
If the clip creates a gap for drainage, then water drainage is improved, but the gap may interfere with cladding installation
Solution Approach 1:
The drainage slots are created at specific localized positions through the retainer clip structure, rather than creating gaps throughout the entire assembly. The slots are positioned to provide drainage functionality while maintaining a relatively smooth exterior surface that does not interfere with cladding installation.

AI summary
An insulation clip which is used to retain insulation in place before materials are placed over the insulation during the construction of a wall assembly. The clip is configured to be snapped onto either a horizontally disposed girt or a vertically disposed girt. The clip not only maintains the insulation in place but creates a gap between the outer side of the insulation and the cladding which is placed thereon.
