Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a three-dimensional structure is formed by laminating thin plate-like section members using powder and binding solution, then manufacturing efficiency and structural integrity are improved, but light stability of the structure deteriorates
Solution Approach 1:
The patent applies parameter changes by introducing light stabilizers with specific concentration ratios into the formation composition and binding solution. The key parameter changed is the concentration ratio of light stabilizer A to light stabilizer B (A/B ratio between 0.1 and 10), which directly addresses the light stability issue while maintaining the existing lamination manufacturing process. This allows the process to produce light-stable three-dimensional structures without sacrificing manufacturing efficiency.
Solution Approach 2:
The patent employs composite materials by combining multiple light stabilizers (light stabilizer A and light stabilizer B) with different chemical characteristics in specific ratios within the formation composition and binding solution. This composite approach creates a synergistic effect that enhances light stability beyond what single stabilizers could achieve, while maintaining compatibility with the powder lamination process.
2Reliability
If light stabilizer concentration is increased to improve light stability, then durability is improved, but manufacturing cost and composition complexity increase
Solution Approach 1:
The patent optimizes the concentration parameters of light stabilizers to achieve effective light stability without excessive complexity. By specifying the A/B ratio range (0.1 to 10) and individual concentration ranges (light stabilizer A: 0.03-1.0 mass%, light stabilizer B: 0.01-0.35 mass%), the patent finds the optimal parameter window that balances performance with simplicity, avoiding the need for complex multi-component systems.
