Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the adjustment range of the actuating unit is structurally limited to prevent excessive tipping moments, then the tilting stability is improved, but the operating range and versatility of the construction machine deteriorates
Solution Approach 1:
The patent applies dynamics by transitioning from static structural limitations to dynamic computational determination of the adjustment range. The control unit continuously calculates the permissible adjustment range based on real-time operating conditions (load, position, support reactions), allowing the limits to adapt dynamically rather than being fixed structurally. This enables the system to maintain stability while expanding the operating range.
Solution Approach 2:
The patent changes the parameter of adjustment range from a fixed structural constraint to a variable parameter determined by multiple factors including support reactions, load magnitude, and position. The control unit modifies the permissible adjustment range based on changing operating parameters, allowing the system to optimize between stability and versatility depending on current conditions.
2Stability of the object's composition
If numerous measuring elements and pressure measuring elements are provided to determine adjustment range while maintaining stability, then the tilting stability is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing measuring elements that serve multiple functions. The sensors detect both position data and load data, which are then used by the control unit to calculate both the adjustment range and to monitor stability. This multi-functional approach reduces the total number of dedicated measuring elements needed compared to specialized single-function sensors.
Solution Approach 2:
The control unit acts as an intermediary that processes data from measuring elements and translates it into actionable information about the adjustment range. Rather than having complex mechanical limit stops or multiple specialized sensors, the control unit mediates between the raw sensor data and the stability control, simplifying the overall system architecture.
3Adaptability or versatility
If the adjustment range is dynamically determined based on condition data including load and position, then the versatility and working radius are improved, but the extent of automation and control complexity increases
Solution Approach 1:
The patent implements feedback by continuously monitoring operating conditions (support reactions, load, position) and using this information to dynamically adjust the permissible adjustment range. The control unit receives feedback from sensors and automatically modifies the adjustment limits, creating a closed-loop control system that balances automation with operational safety.
