Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional laser machine with orthogonal axis type machining tool, robot, or positioner is used, then machining precision can be maintained within constraints, but the machine is limited by workpiece size and posture constraints requiring separate machines for different dimensions and shapes
Solution Approach 1:
The patent applies universality by enabling a single laser machine system to perform machining operations on workpieces of various sizes and shapes. The flying body with laser radiation function can adapt to different workpiece configurations without requiring separate dedicated machines, achieving multi-functionality in one system
Solution Approach 2:
The patent replaces traditional mechanical positioning systems (orthogonal axis type machining tools, robots, positioners with servo motors) with a flying body that uses flight control for positioning. This substitution eliminates mechanical constraints on workpiece size and posture while maintaining machining precision through detector-based feedback
2Adaptability or versatility
If a flying body with laser radiation function is used, then access to complex areas and flexibility are improved, but machining precision is insufficient without position detection and scanning control
Solution Approach 1:
The patent implements feedback by using a position/posture detector to continuously monitor the flying body's location and orientation relative to the workpiece. This detection information is fed back to the radiation position changer, which adjusts the laser beam direction in real-time to maintain precise machining accuracy despite the flying body's movement
Solution Approach 2:
The patent applies dynamics by making the laser radiation system adaptive and movable rather than fixed. The flying body dynamically positions itself in three-dimensional space, and the radiation position changer dynamically adjusts beam direction based on real-time detection, enabling precision machining while accessing complex areas
3Manufacturing precision
If multiple laser machines are used to handle different workpiece dimensions and shapes, then machining precision for each specific type is maintained, but the number of machines and system complexity increase
Solution Approach 1:
The patent consolidates multiple specialized laser machines into a single universal system. The flying body with detector-based position control can adapt to different workpiece types through software control and real-time positioning, eliminating the need for multiple dedicated machines while maintaining precision for each workpiece category
