Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a low-viscosity polymer is used to improve handling properties, then the handleability of the composition set is improved, but the elongation at break of the cured product decreases
Solution Approach 1:
The patent changes the chemical structure parameters of the polymer by introducing a polyoxyalkylene chain with 100 or more oxyalkylene groups into the compound of formula (1). This structural modification enables the polymer to simultaneously achieve low viscosity for good handleability and high elongation at break for improved mechanical properties in the cured product.
Solution Approach 2:
The patent creates a composite molecular structure combining the polyoxyalkylene chain with the compound of formula (1). This composite structure integrates the flow-enhancing properties of polyoxyalkylene with the reactive and mechanical properties of the acrylate/methacrylate compound, achieving both low viscosity and high elongation at break.
2Ease of operation
If the viscosity of the polymer is reduced to improve handleability, then the composition set becomes easier to handle, but the mechanical properties of the cured product deteriorate
Solution Approach 1:
The patent modifies the molecular parameters by incorporating a polyoxyalkylene chain with 100 or more oxyalkylene groups, which changes the viscosity characteristics while maintaining or enhancing the mechanical reliability of the cured product through the specific chemical structure of formula (1).
Solution Approach 2:
The composite structure of polyoxyalkylene chain combined with compound (1) creates a material that exhibits both low viscosity for ease of handling and high mechanical reliability including elongation at break of 100% or more in the cured state.
3Strength
If a polymer with high elongation at break is used to improve mechanical properties, then the cured product achieves high elongation, but the viscosity increases reducing handleability
Solution Approach 1:
The patent achieves high elongation at break by incorporating 100 or more oxyalkylene groups in the polyoxyalkylene chain, while simultaneously maintaining low viscosity through the specific chemical structure and molecular weight control of the compound of formula (1).
Solution Approach 2:
The composite molecular architecture combining polyoxyalkylene chain with compound (1) creates a material system where the polyoxyalkylene provides elongation capability while the overall structure maintains low viscosity for excellent handleability.
