Insulation Wall Anchor Sleeve Structure for Heat and Moisture Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing external wall insulation systems using self-tapping screws suffer from heat and moisture leakage through gaps, and the screws are prone to rust and aging.
Innovation Solution
A wall anchor with a main body and sleeve member, where the main body has a radial flange with a non-circular cross-section and a sleeve member with a circular cross-section, providing structural stability and covering gaps to reduce heat and moisture transfer, made from zinc alloy for strength and nylon for durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If self-tapping screws are used to mount insulation board, then the insulation board can be fixed to the wall, but gaps are formed between the insulation board and screws causing heat and moisture leakage
Solution Approach 1:
The patent introduces a wall anchor as an intermediary component between the insulation board and the wall. The wall anchor includes a main body with a radial flange that embeds into the wall and a head portion that contacts the insulation board, providing a reliable fixing connection while eliminating gaps that cause heat and moisture leakage.
Solution Approach 2:
The wall anchor is made from zinc alloy material that combines high strength, corrosion resistance, and thermal insulation properties. This composite material approach allows the single component to simultaneously provide mechanical fixing, prevent harmful leakage, and offer thermal insulation without requiring multiple separate components.
2Ease of manufacture
If self-tapping screws are used for mounting, then installation is simple, but the screws are prone to rust and aging reducing durability
Solution Approach 1:
The patent changes the material parameter from conventional steel self-tapping screws to zinc alloy material. This parameter change provides superior corrosion resistance and durability while maintaining ease of installation through the threaded body design. The zinc alloy material inherently resists rust and aging that plague traditional steel screws.
3Stability of the object's composition
If a radial flange with non-circular cross-section is used in the wall anchor, then structural stability is improved, but manufacturing complexity increases
Solution Approach 1:
The radial flange is designed with a non-circular cross-section featuring asymmetric geometry with flat surfaces and arcuate surfaces. This asymmetric design prevents rotation of the wall anchor within the wall bore, providing enhanced structural stability and ensuring proper orientation during installation, while the overall structure remains manufacturable through standard molding processes.
