Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional injection bonding methods for repairing hollow profiles, especially in vehicle construction, face challenges such as incomplete adhesive filling due to capillary effects, complex geometries, and surface properties, leading to inadequate bonding and increased difficulty in accessing and assembling damaged composite profiles, resulting in costly and labor-intensive repairs.
Innovation Solution
An adhesive distribution device with a multidirectional channel system and strategically positioned outlet openings is used to ensure even and complete filling of the adhesive gap, allowing for targeted adhesive distribution along the flow fronts, preventing adhesive escape and ensuring reliable bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional injection bonding methods are used, then the bonding process is simple, but the adhesive filling is incomplete due to capillary effects and complex geometries
Solution Approach 1:
The adapter body is divided into multiple channels with separate outlet openings, allowing the adhesive to be distributed through multiple pathways simultaneously. This segmentation overcomes the limitation of single-point injection and ensures complete filling of complex geometries by addressing different regions independently.
Solution Approach 2:
The adapter body acts as an intermediary device between the adhesive source and the bonding gap. It contains the channel system that mediates the adhesive flow, transforming the single-point injection into multi-point distribution, thereby ensuring uniform and complete adhesive filling.
2Reliability
If adhesive is injected into the bonding gap, then bonding is achieved, but adhesive escape occurs leading to loss of substance
Solution Approach 1:
The adapter body is pre-positioned in the bonding gap before adhesive injection, establishing controlled flow pathways and outlet openings at optimal locations. This preliminary positioning ensures that adhesive is directed precisely where needed and prevents uncontrolled escape, thereby reducing adhesive loss while maintaining bonding reliability.
3Ease of repair
If repair profiles are accessed and assembled, then damaged profiles are repaired, but accessibility is difficult leading to increased labor time
Solution Approach 1:
The adapter body serves multiple functions: it distributes adhesive through multiple channels, positions outlet openings at optimal locations, and facilitates easy assembly and disassembly. This multi-functionality improves repair accessibility and reduces labor time by combining several operations into a single device.
4Manufacturing precision
If adhesive is distributed through single injection point, then injection is simple, but distribution is uneven along flow fronts
Solution Approach 1:
The channel system is segmented into multiple independent pathways, each with its own outlet opening positioned at different locations. This segmentation allows adhesive to flow through multiple routes simultaneously, ensuring uniform distribution along flow fronts and overcoming the limitations of single-point injection.
