Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning is used for adsorption machining robots, then the robot can be positioned at the processing location, but it is inefficient and creates safety hazards when large components have multiple surfaces to be processed or are fixed in high positions
Solution Approach 1:
The robot transitions from static manual positioning to dynamic autonomous navigation. The mobile platform with omnidirectional wheels enables the robot to autonomously move to different processing positions on large workpieces, eliminating the need for manual positioning and significantly improving processing efficiency while maintaining safety.
Solution Approach 2:
The robot equips itself with navigation and positioning capabilities through integrated sensors and control systems. It can autonomously determine its location, plan paths, and navigate to processing positions without human intervention, making the system self-sufficient in positioning tasks.
2Device complexity
If traditional adsorption machining robots rely only on adsorption force to resist processing forces, then the structure remains simple, but the robot produces small skidding or large movements during drilling and milling operations, seriously affecting processing accuracy and quality
Solution Approach 1:
The patent combines adsorption force with mechanical locking forces in a hybrid fixation system. The adsorption module provides initial attachment while the locking module with expanding bolts provides mechanical constraint, creating a combined system that prevents both skidding and large movements during high-force operations like drilling and milling.
Solution Approach 2:
The adsorption force is applied first to attach the robot to the workpiece surface, and then the locking mechanism is activated to provide additional mechanical constraint. This preliminary adsorption action prepares the system for the subsequent locking action, ensuring stable fixation before high-force processing operations begin.
3Device complexity
If cutting chips remain in the adsorption device, tool, and locking device, then the structure remains simple, but the chips affect adsorption and locking effects, scratch workpiece surfaces, and reduce processing quality
Solution Approach 1:
The patent extracts cutting chips from the system through dedicated cleaning mechanisms. Air blowers and brushes are integrated into the adsorption and locking modules to actively remove chips from critical surfaces, preventing them from interfering with adsorption, locking, and workpiece quality while maintaining relatively simple overall structure.
Solution Approach 2:
Air flow and brush elements serve as intermediary cleaning agents between the cutting chips and critical surfaces. These intermediaries capture and remove chips from the adsorption device, tool, and locking device, protecting the workpiece and maintaining processing quality without requiring complex mechanical cleaning systems.
