Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fasteners with tension displacement indicators are difficult and time-consuming to manufacture due to the use of non-light curable adhesives, requiring extended curing times and impractical production processes.
Innovation Solution
The use of light curable adhesives, such as those cured by visible, UV, or blue light, to accelerate the assembly and calibration of fasteners with tension displacement indicators, allowing for faster manufacturing by reducing curing time significantly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If non-light curable adhesives are used to attach the indicator components, then the bond strength and reliability are improved, but the manufacturing time and production efficiency deteriorate significantly
Solution Approach 1:
The patent changes the chemical parameter of the adhesive from non-light curable to light curable formulation, allowing the same bonding function to be achieved with dramatically reduced curing time when exposed to appropriate wavelengths of light
Solution Approach 2:
The patent replaces the time-dependent chemical curing process with a light-triggered curing mechanism, where UV or visible light initiates rapid polymerization of the adhesive, substituting prolonged ambient curing with controlled optical activation
2Reliability
If extended curing time is used for the adhesive to ensure proper bonding, then the quality and reliability of the fastener are improved, but the production time and manufacturing cost increase
Solution Approach 1:
The patent applies the adhesive in an uncured state during assembly, then activates the curing process on-demand using light exposure, allowing components to be positioned and bonded simultaneously without waiting for extended curing periods
3Ease of manufacture
If traditional manufacturing processes with non-light curable adhesives are used, then the assembly can be performed without specialized equipment, but the production efficiency and manufacturing speed decrease
Solution Approach 1:
The patent selects light curable adhesives that can be cured by multiple wavelengths including UV and visible blue light, allowing the same adhesive system to work with different light sources and manufacturing setups, from simple LED lamps to sophisticated curing systems
