Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UV curable resin is used instead of AB two-component epoxy resin, then operating time flexibility and curing speed are improved, but formulation complexity increases
Solution Approach 1:
The patent changes the chemical parameters of the resin system by replacing traditional epoxy resin with UV-curable acrylate resin. This fundamental parameter change enables the resin to cure under UV light irradiation rather than requiring extended chemical reaction time, thus dramatically improving curing speed while maintaining manageable formulation complexity through careful selection of resin, monomer, and photoinitiator components.
Solution Approach 2:
The patent substitutes the chemical curing mechanism (slow chemical reaction of epoxy resin) with a photochemical curing mechanism (UV light-induced polymerization). This replacement of the curing system allows for rapid solidification upon UV exposure, significantly enhancing productivity without introducing excessive complexity into the overall formulation.
2Stability of the object's composition
If AB two-component epoxy resin is used, then material stability is improved, but operating time window becomes extremely narrow
Solution Approach 1:
The patent applies preliminary action by incorporating a polymerization inhibitor into the UV curable resin formulation. This inhibitor prevents premature polymerization during storage and handling, maintaining material stability. When UV light is applied, the inhibitor is deactivated and rapid curing occurs, thus extending the effective operating time window while preserving material stability throughout the process.
Solution Approach 2:
The patent uses a polymerization inhibitor as an intermediary substance that mediates between material stability and reactivity. The inhibitor remains active during storage to prevent spontaneous polymerization, then gets deactivated by UV light to allow curing. This intermediary mechanism resolves the contradiction between maintaining stability and enabling extended operability.
3Strength
If AB two-component epoxy resin is used, then adhesion strength is improved, but environmental requirements become extremely strict
Solution Approach 1:
The patent changes the curing condition parameters from requiring controlled temperature and humidity (5-35°C, 50%-70% humidity) to requiring only UV light irradiation. This parameter change in the curing mechanism allows the resin to cure under diverse environmental conditions, significantly improving environmental adaptability while maintaining adhesion strength through the UV-cured polymer network structure.
Solution Approach 2:
The patent substitutes the environmental-dependent chemical curing process of epoxy resin with a photochemical curing process that is independent of temperature and humidity conditions. This replacement eliminates the strict environmental requirements while preserving strong adhesion through the cross-linked polymer structure formed by UV curing.
4Reliability
If AB two-component epoxy resin is used, then material reliability is improved, but material loss and waste increase significantly
Solution Approach 1:
The UV curable resin system is designed to be used in smaller, more manageable quantities that can be cured rapidly in place. The material reliability is maintained through proper formulation with stabilizers and inhibitors that prevent degradation. This self-service approach allows for precise application and minimal waste, as the resin cures quickly where applied rather than requiring large batches to be mixed and used within a narrow time window.
