Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of work implement tilt is used, then the machine can perform horizontal control, but work efficiency is reduced depending on user skill level
Solution Approach 1:
The patent replaces manual mechanical adjustment of the work implement tilt with an automated control system that uses sensors to detect the machine's attitude (roll and pitch angles) and automatically adjusts the work implement's horizontal position. This substitution eliminates the need for operator skill in manual tilt adjustment, improving both ease of operation and work efficiency.
Solution Approach 2:
The system enables the work machine to automatically adjust its own horizontal control without external manual intervention. The control unit continuously monitors the machine's attitude through sensors and autonomously adjusts the work implement's tilt angle to maintain proper horizontal alignment, making the system self-regulating and independent of operator skill level.
2Productivity
If automated horizontal control is implemented, then work efficiency is improved, but device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it processes data from multiple sensors (roll angle, pitch angle), calculates the appropriate tilt adjustment, controls the hydraulic actuator, and maintains horizontal alignment across different working conditions. This multi-functionality consolidates what could be separate complex systems into a single integrated control unit, improving efficiency while managing complexity.
Solution Approach 2:
The system implements a closed-loop feedback control mechanism where sensors continuously monitor the machine's actual attitude (roll and pitch angles), the control unit compares this with the desired horizontal position, and automatically adjusts the work implement tilt to eliminate any deviation. This feedback mechanism enables precise automated control without requiring overly complex manual control systems.
