Solution Overview
Problem
Traditional coupling methods, such as fasteners and welding, increase part counts, assembly time, and require machining operations, which can lead to complexity and expense, especially when aiming for waterproof or airtight seals.
Innovation Solution
A method utilizing electromagnetic energy to couple components with a susceptor and hot melt adhesive, where the susceptor converts electromagnetic energy to heat, melting the adhesive and bonding the components upon solidification, eliminating the need for machining and reducing part counts and assembly time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional coupling methods such as fasteners and welding are used, then components can be coupled together, but part counts increase and assembly time increases
Solution Approach 1:
The patent combines multiple functions into a single adhesive layer that simultaneously couples components together and provides waterproof/airtight sealing. This eliminates the need for separate fasteners, welds, and sealants, thereby reducing part counts and simplifying the assembly process while maintaining structural integrity and environmental sealing.
Solution Approach 2:
The patent replaces mechanical coupling methods (fasteners, welding) with a chemical bonding system using electromagnetic-cured adhesive. This substitution eliminates complex mechanical assembly steps, reduces part counts, and enables faster assembly while achieving equivalent or superior coupling strength and sealing performance.
2Ease of manufacture
If traditional coupling methods such as fasteners and welding are used, then components can be coupled together, but machining operations are required which increase complexity and expense
Solution Approach 1:
The patent replaces mechanical machining operations with a chemical bonding process. Instead of requiring precision-machined surfaces for fasteners or welds, the adhesive can be applied to prepared surfaces and cured to create strong bonds, eliminating expensive and time-consuming machining operations while reducing overall manufacturing complexity.
Solution Approach 2:
The patent changes the bonding mechanism from mechanical (requiring precise dimensional tolerances and machining) to chemical (using adhesive properties and curing parameters). This allows for greater flexibility in surface preparation and reduces the need for tight tolerances and complex machining operations, simplifying the manufacturing process.
3Reliability
If traditional joint seals such as O-rings are used to seal junctions, then waterproof or airtight seals can be achieved, but part counts increase and assembly complexity increases
Solution Approach 1:
The patent merges the coupling function and sealing function into a single adhesive layer. The same electromagnetic-cured adhesive that bonds components together also provides waterproof and airtight sealing at the junction, eliminating the need for separate O-rings or gaskets and reducing part counts while maintaining reliable environmental sealing.
Solution Approach 2:
The adhesive system performs multiple functions simultaneously: it couples components together structurally and provides environmental sealing. This multi-functionality eliminates the need for separate sealing components, reduces assembly complexity, and maintains reliable waterproof and airtight performance.
