Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex individual calculations are performed for each construction machine to achieve precise automatic operation, then the manufacturing precision and reliability of automatic operation is improved, but the device complexity and calculation time increase significantly
Solution Approach 1:
The patent creates a universal automatic operation program that can be applied to multiple construction machines of the same type. Instead of creating separate programs for each machine, a single program with common parameters (bucket capacity, work member dimensions) can control multiple machines, reducing calculation complexity while maintaining operation precision through parameter adjustment rather than complete recalculation.
Solution Approach 2:
The patent divides the automatic operation program into two parts: common parameters that apply to all machines of the same type (work member dimensions, bucket capacity) and individual parameters specific to each machine. This segmentation allows the majority of calculations to be performed once universally, with only minor parameter adjustments needed for individual machines, thereby reducing overall calculation complexity.
2Manufacturing precision
If complex angle calculations are performed for each component (turning body, boom, arm, bucket) to achieve precise motion control, then the manufacturing precision of motion control is improved, but the calculation time and system complexity increase
Solution Approach 1:
The patent performs preliminary calculations of motion angles and positions during the program creation phase, storing these as pre-calculated data. When the program is executed on different machines, these pre-calculated angle values are reused with minor adjustments, eliminating the need for real-time complex trigonometric calculations and significantly reducing execution time while maintaining precision.
3Reliability
If individualized programs are created for each construction machine based on specific parameters, then the reliability of automatic operation is improved, but the adaptability across multiple machines decreases
Solution Approach 1:
The patent designs the automatic operation program with universal applicability to multiple construction machines of the same type by using standardized parameter structures. The program can accommodate different bucket capacities and machine specifications through parameter input rather than structural modification, maintaining reliability through consistent calculation methods while achieving versatility across multiple machines.

AI summary
Provided are a system and a method that allow information for automatic operation of a construction machine to be acquired only by designating an operation of a work member. The system includes an intermediate motion information calculation part. The intermediate motion information calculation part calculates intermediate motion information on a motion of an intermediate mechanism based on work motion information that is set for the motion of the work member. The work member performs a work motion for achieving a predetermined work application in the construction machine. The work motion information includes a plurality of motion information elements, which include elapsed time, work member position information, and work member posture information.
