Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional movement mechanisms and jig or clamp mechanisms are used to precisely move workpieces and prevent position gaps, then positioning precision is improved, but device complexity and production cost increase
Solution Approach 1:
The patent replaces complex mechanical positioning mechanisms with a vision sensor-based detection system and control system. The vision sensor detects workpiece position, the control system calculates position differences, and the drive mechanism adjusts positioning based on calculated data, eliminating the need for complex mechanical positioning devices and jigs.
Solution Approach 2:
The patent implements a closed-loop feedback system where the vision sensor continuously detects workpiece position, the control system compares detected position with target position to calculate differences, and the drive mechanism adjusts positioning based on this feedback. This feedback loop enables precise positioning without complex mechanical mechanisms.
2Manufacturing precision
If conventional movement mechanisms and jig or clamp mechanisms are used to precisely move workpieces and prevent position gaps, then positioning precision is improved, but production cost increases
Solution Approach 1:
The patent replaces expensive mechanical positioning mechanisms with a more cost-effective combination of vision sensor, control system, and simple drive mechanism. This substitution reduces production costs while maintaining positioning precision through intelligent control rather than complex mechanics.
Solution Approach 2:
The system enables the workpiece positioning process to self-correct through automated detection and adjustment. The vision sensor detects position errors, the control system calculates corrections, and the drive mechanism automatically adjusts positioning, eliminating the need for expensive manual positioning mechanisms and reducing overall system cost.
3Manufacturing precision
If vision sensor repeatedly detects workpiece position and control system continuously adjusts movement, then positioning precision is improved, but measurement and control difficulty increases
Solution Approach 1:
The patent uses a systematic feedback approach where the vision sensor detects workpiece position, the control system automatically calculates position differences and determines correction amounts, and the drive mechanism applies adjustments. This automated feedback loop simplifies the control process despite repeated measurements by using algorithmic calculation rather than complex manual control.
Solution Approach 2:
The control system acts as an intermediary that simplifies the interaction between the vision sensor and drive mechanism. It receives detection data, calculates position differences and correction amounts using predetermined algorithms, and generates control signals for the drive mechanism, making the overall measurement and control process more manageable.

AI summary
A workpiece positioning device has a more simple structure and a low cost. The workpiece positioning device includes a movable base on which a workpiece is placed, drive mechanisms for moving the movable base, a vision sensor for repeatedly detecting the current position of the workpiece placed on the movable base, a difference calculating part for calculating the difference between the current position and the target position each time the current position is detected by the vision sensor, a difference determining part for determining whether the difference is within an allowable range, and a drive controller for controlling the drive mechanisms so as to stop the movement of the movable base when it is determined that the difference is within the allowable range.
