Engineering Contradiction Analysis
1Productivity
If conventional bucket assembly designs are used with varying geometric parameters, then manufacturing flexibility is maintained, but loadability and operational efficiency deteriorate
Solution Approach 1:
The patent applies parameter changes by specifying precise geometric ratios (first length to second length between 0.95-1.05) and specific angle ranges (first angle α between 17.8°-23.8°, second angle β between 23.0°-29.0°) to optimize the bucket assembly's loadability and operational efficiency. This transforms the conventional variable-parameter design into a controlled parameter range design that balances performance optimization with manufacturing feasibility.
2Productivity
If the middle section is made curved to enhance material flow, then material handling efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The patent implements spheroidality by configuring at least a portion of the middle section with a curved geometry. This curvature is specifically designed to enhance material flow and handling efficiency within the bucket assembly, allowing material to move more smoothly from the bottom section to the top section during loading and transport operations.
3Ease of operation
If the first length to second length ratio is optimized to 0.95-1.05 for balanced center of mass, then operational efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies parameter changes by defining a specific ratio range (0.95-1.05) for the first length to second length, which positions the center of mass to enhance operational efficiency. This range-based specification balances the need for precise center of mass control with practical manufacturing capabilities, allowing some tolerance while maintaining performance benefits.
4Loss of substance
If spill guards are strategically positioned to reduce material spillage, then material retention is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by strategically positioning spill guards at specific locations on the bucket assembly before material loading occurs. This preventive configuration of spill guards at predetermined positions reduces material spillage during operation without requiring complex active control systems or additional operational steps.

AI summary
A machine bucket may include an upper pin hole and a lower pin hole. The machine bucket may also include a bottom section. A distance between the lower pin hole and a tip of the bottom section may have a first length. The machine bucket may also include a top section. A distance between the lower pin hole and a tip of the top section may have a second length. A ratio of the first length to the second length may be equal to a value between approximately 0.95 and 1.05. The machine bucket may further include a middle section located between the bottom section and the top section. At least a portion of the middle section may be curved.
