Adhesive Mounting Structure With Flow Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive mounting structures have deficiencies such as reduced bonding strength and excessive adhesive use, and conventional welding methods are not viable for end-of-line installations or retrofit improvements, which can compromise structural integrity.
Innovation Solution
The proposed adhesive mounting structure features a base with an outer and inner face, including an adhesive injection port, a primary adhesive flow path, and multiple secondary flow paths on the inner face, with a textured surface and an adhesive overflow port, made from non-reinforced resin with a flex modulus less than 4 GPA, to optimize adhesive distribution and bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding technique is used to attach hardware to structure, then bonding strength is improved, but structural integrity deteriorates and adaptability worsens
Solution Approach 1:
The patent replaces the mechanical welding system with an adhesive bonding system. The adhesive mounting structure uses chemical adhesion instead of mechanical welding to attach hardware to the structure, thereby maintaining bonding strength while improving adaptability for end-of-line installations and retrofit improvements without compromising structural integrity.
Solution Approach 2:
The patent introduces an adhesive as an intermediary substance between the hardware and the structure. The adhesive mounting structure with flow paths allows the adhesive to be distributed evenly, creating a chemical bond that replaces the direct mechanical weld, thus achieving both strength and adaptability.
2Manufacturing precision
If adhesive flow channel is provided for guided adhesive flow, then adhesive distribution is improved, but bonding strength deteriorates
Solution Approach 1:
The patent applies local quality by providing a textured surface at specific locations on the mounting structure. The textured surface is located at the adhesive flow paths to enhance adhesive retention and bonding strength locally, while the overall adhesive distribution is controlled by the flow channel geometry. This localized texturing prevents excessive adhesive flow without compromising overall distribution precision.
3Strength
If textured surface is provided on adhesive flow paths, then bonding strength is improved, but adhesive usage increases
Solution Approach 1:
The textured surface is applied locally only at critical bonding areas on the adhesive flow paths rather than across the entire mounting structure. This localized texturing enhances adhesive retention and bonding strength at key locations while minimizing the total quantity of adhesive required, as the adhesive is concentrated where it provides maximum bonding benefit.

AI summary
A mounting structure for adhesively bonding onto a surface includes a base, an outer face of the base and an inner face of the base. An adhesive injection port is provided on the outer face of the base for supplying an adhesive. A primary adhesive flow path is provided on the inner face of the base. The primary adhesive flow path is in fluid communication with the adhesive injection port and allows the adhesive to flow. Further, a plurality of secondary adhesive flow paths originating from the primary adhesive flow path allow the adhesive to distribute on the inner face.
