Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional obstacle detection methods are used for engineering machinery, then the device complexity is low, but the measurement precision of obstacle detection is insufficient leading to missed collision judgments
Solution Approach 1:
The patent combines multiple sensing devices (environmental sensing devices and boom motion sensing devices) into an integrated detection system. The environmental sensing devices detect obstacle information in both boom slewing motion direction and boom luffing motion direction, while the boom motion sensing devices track boom position and movement. These multiple sensing systems are merged to provide comprehensive obstacle detection and collision judgment, resolving the contradiction between detection precision and device complexity.
Solution Approach 2:
The control device serves as an intermediary that receives and processes information from multiple sensing devices. It integrates obstacle information from environmental sensing devices with boom motion information from boom motion sensing devices, performs collision judgment based on this fused information, and generates appropriate control signals. This intermediary processing enables precise collision detection without requiring direct complex interaction between multiple sensing devices.
2Adaptability or versatility
If static collision detection methods are used, then the ease of operation is high, but the adaptability to dynamic operation spaces is poor resulting in missed collision judgments
Solution Approach 1:
The patent implements a dynamic collision detection system where the control device continuously receives real-time obstacle information from environmental sensing devices and real-time boom motion information from boom motion sensing devices. The system dynamically updates the collision judgment based on current boom position, movement direction, and detected obstacles, enabling adaptation to changing operation spaces while maintaining automated operation that preserves ease of use.
Solution Approach 2:
The system establishes a feedback loop where the control device receives continuous information from sensing devices, performs real-time collision judgment, and can issue control signals back to the engineering machinery. This feedback mechanism enables the system to adapt to dynamic operation conditions by continuously monitoring and responding to changes in boom position and obstacle locations, improving adaptability while maintaining automated operation.
3Reliability
If comprehensive environmental sensing is implemented in all directions, then the reliability of collision detection is improved, but the device complexity increases due to multiple sensing devices
Solution Approach 1:
The patent segments the detection task by dividing it into two functional components: environmental sensing devices for detecting obstacles in boom slewing motion direction and boom luffing motion direction, and boom motion sensing devices for tracking boom position and movement. This segmentation allows each sensing device to be optimized for its specific function while collectively providing comprehensive collision detection coverage, improving reliability without excessive overall complexity.
Solution Approach 2:
The control device performs multiple functions: it processes obstacle information from environmental sensing devices, processes boom motion information from boom motion sensing devices, performs collision judgment by integrating both information types, and generates control signals. This multi-functional control device reduces the need for separate specialized systems, achieving reliable collision detection while managing overall system complexity through functional integration.
