Adhesive Aid Insert for Bonding Components with Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When bonding flat components with openings, adhesive often enters and accumulates in these openings, complicating pre- and post-processing tasks such as removing excess adhesive and ensuring a clean joint.
Innovation Solution
A bonding aid with an insertion section that fits into the opening and a flexible displacement section that projects radially to prevent adhesive from entering the opening, ensuring the adhesive remains within the bond gap and can be easily removed without damaging the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is applied to bond components with openings, then bonding is achieved, but adhesive enters and accumulates in the openings making pre- and post-processing difficult
Solution Approach 1:
A bonding aid is introduced as an intermediary element that temporarily occupies the opening during the bonding process. The bonding aid has an insertion section that fits into the opening and a displacement section that prevents adhesive from entering the opening, thus mediating between the adhesive application and the opening to avoid contamination while maintaining bonding quality
Solution Approach 2:
The bonding aid is inserted into the opening before adhesive application. This preliminary action prepares the opening by blocking it, preventing the subsequent harmful effect of adhesive intrusion, and enabling clean bonding without requiring complex post-processing to remove adhesive from openings
2Reliability
If adhesive is applied generously to ensure complete coverage, then bonding reliability improves, but adhesive contamination in openings increases
Solution Approach 1:
The bonding aid serves as a protective intermediary that blocks the opening during adhesive application. This allows adhesive to be applied generously for complete coverage and bonding reliability while the bonding aid prevents the adhesive from entering and contaminating the opening
Solution Approach 2:
The bonding aid is inserted into the opening before adhesive application to create a preliminary protective barrier. This anti-action prevents the harmful effect of adhesive contamination while allowing the bonding process to proceed with sufficient adhesive coverage for reliable bonding
3Stability of the object's composition
If the bonding aid is made rigid to maintain shape, then structural stability improves, but flexibility to adapt to opening contours decreases
Solution Approach 1:
The bonding aid has different local properties: the insertion section is made flexible to adapt to the opening contours and insert smoothly, while the displacement section has sufficient rigidity to effectively block and displace adhesive. This local differentiation of mechanical properties resolves the contradiction between overall structural stability and local adaptability

Function Achieved in This Case
The bonding aid effectively prevents adhesive from entering openings, simplifying the bonding process by maintaining a clean joint and allowing for easy removal without damaging the components, thus reducing preparatory and post-adhesion work.

AI summary
The invention relates to an adhesive aid (4) and a method for adhering components (1, 2) by means of an adhesive (8) which can be found in an adhesive gap between respective adhesive surfaces (1a, 2a) of the components (1, 2). At least the first component (1) has an opening which opens into the component adhesive surface (1a). The adhesive aid (4) has an insert portion (6), which is designed to be inserted into the opening and has an insert outer contour that correlates to an inner contour of the opening, and a displacement portion (7), which adjoins the insert portion (6) in order to displace adhesive (8) in the adhesive gap. The displacement portion (7) has a protrusion which protrudes past the insert outer contour in the radial direction, and the displacement portion is designed to be flexible, in particular elastic, at least in the region of the protrusion.
