Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If quartz sand is used as filler in curable casting compounds, then mechanical strength and structural stability are improved, but resource depletion and environmental harm worsen due to massive sand consumption
Solution Approach 1:
The patent changes the material parameter of the filler from quartz sand to ground fruit kernels and shells, transforming the composition while maintaining the structural function. This substitution resolves the environmental harm caused by sand extraction while preserving the mechanical strength required for molded articles
Solution Approach 2:
The patent recovers waste fruit kernels and shells that would otherwise be discarded, transforming them into valuable filler material. This approach addresses resource depletion by utilizing agricultural waste products instead of extracting natural sand resources
2Reliability
If quartz sand is used as filler, then manufacturing reliability is improved, but resource availability deteriorates due to sand shortage
Solution Approach 1:
The patent employs abundant agricultural waste materials (fruit kernels and shells) as filler substitutes, replacing the finite quartz sand resource. These waste materials are readily available and can be sustainably sourced, ensuring long-term manufacturing reliability without depleting sand reserves
Solution Approach 2:
The patent makes the casting compound formulation more universal by accepting various types of ground fruit kernels and shells as fillers. This multi-functionality allows the manufacturing process to adapt to different available waste materials, ensuring continued production even when specific sand sources become unavailable
3Weight of moving object
If ground fruit kernels and shells are used as filler, then weight is reduced and impact resistance is improved, but manufacturing complexity increases due to new material processing
Solution Approach 1:
The patent changes the density parameter of the filler material by substituting heavy quartz sand with lighter fruit kernel and shell particles. This parameter change directly reduces the weight of the molded article while improving impact resistance through the unique cellular structure of the fruit materials
Solution Approach 2:
The patent replaces the mechanical grinding and processing of quartz sand with similar processing of fruit kernels and shells. The existing milling and classification equipment can be adapted with minimal modification, reducing the actual increase in manufacturing complexity despite the new material
4Object-affected harmful factors
If fruit kernels and shells are used as filler, then environmental sustainability is improved, but filler performance consistency worsens due to natural material variability
Solution Approach 1:
The patent controls the particle size parameter of the ground fruit kernels and shells to ensure consistency. By establishing standardized grinding and classification processes, the natural variability of the source material is minimized, producing filler with uniform properties that ensure stable casting compound performance
Solution Approach 2:
The patent applies different processing conditions to different batches of fruit kernels and shells to achieve uniform filler properties. By adjusting local processing parameters such as grinding time, screen mesh size, and classification settings, the natural variations in source material are compensated to produce consistent filler quality
