Metal Interior Attachment Structure With Mechanical Interlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interior material attachment structures for metal plates like aluminum, brass, and copper are costly, inefficient, and require multiple construction processes, often using harmful adhesives, and lack flame retardant properties.
Innovation Solution
A one-touch interior material attachment structure with rectangular binding protrusions and connection grooves, allowing for efficient assembly of metal interior materials on a flat wall surface using connectors, eliminating the need for adhesives and simplifying the construction process while ensuring flame retardancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive is used to attach interior material to metal base material, then adhesion strength is improved, but fire safety deteriorates due to combustible adhesive
Solution Approach 1:
The patent removes the adhesive layer entirely from the attachment system. Instead of using adhesive to bond the interior material to the metal base material, the design uses mechanical interlocking through protrusions and recesses, eliminating the combustible adhesive while maintaining attachment strength
Solution Approach 2:
The patent replaces the chemical bonding mechanism (adhesive) with a mechanical bonding mechanism (protrusion-recess interlocking). The attachment structure uses physical geometric features to achieve strong bonding without requiring any adhesive substance, thereby eliminating fire hazards associated with adhesives
2Reliability
If multiple construction processes are used for attachment, then attachment reliability is improved, but construction time and cost increase
Solution Approach 1:
The patent combines multiple attachment functions into a single integrated structure. The protrusions and recesses are formed as integral parts of the interior material and base material respectively, allowing simultaneous alignment, positioning, and bonding in one operation rather than requiring separate steps for each function
Solution Approach 2:
The attachment structures (protrusions and recesses) are pre-formed during the manufacturing process of the interior material and base material. This preliminary preparation eliminates the need for on-site construction of attachment features, allowing for rapid assembly during installation
3Strength
If adhesive is applied to protect sheet and hot melt sheet, then adhesion property is improved, but flame retardant property deteriorates
Solution Approach 1:
The patent removes the adhesive layer from the protection sheet and hot melt sheet assembly. The attachment is achieved through mechanical interlocking features formed during manufacturing, eliminating the need for adhesive and preserving flame retardant properties
Solution Approach 2:
The patent replaces chemical adhesion (adhesive) with mechanical interlocking (protrusions and recesses). This substitution maintains strong attachment while preserving the flame retardant characteristics of the metal base material and protection sheet
