Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If advanced measuring systems are used for high accuracy positioning, then positioning precision is improved, but system complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical measuring systems with a simplified optical measurement system. An optical sensor detects the position of previously placed objects, and a processing device calculates the deviation between the optical line and the line of sight. This substitution of mechanical systems with optical-electronic systems achieves high positioning precision while reducing system complexity
Solution Approach 2:
The patent uses optical copying principles by projecting an optical line (laser) to create a virtual reference line that represents the desired placement path. The optical sensor detects objects' positions relative to this optical copy of the reference line, enabling precise positioning without physical mechanical guides
2Device complexity
If traditional manual positioning is used, then system complexity is reduced, but positioning accuracy deteriorates due to human error and fatigue
Solution Approach 1:
The patent implements a feedback control system where the optical sensor continuously monitors the position of placed objects, the processing device calculates deviations from the reference line, and the system adjusts subsequent object placements to compensate for accumulated errors. This closed-loop feedback maintains high positioning accuracy without requiring complex manual operations
Solution Approach 2:
The system performs self-positioning by automatically detecting object positions, calculating deviations, and determining correct placement locations without human intervention. The processing device autonomously computes the deviation between the optical line and line of sight, enabling the system to self-correct positioning errors
3Ease of operation
If objects are placed sequentially one by one, then positioning control is simplified, but productivity decreases due to time-consuming manual operations
Solution Approach 1:
The patent establishes a reference line (optical line) in advance before placing objects. This preliminary action creates a fixed reference framework that enables rapid, automated positioning of subsequent objects without requiring complex real-time calculations, thus increasing productivity while maintaining simple positioning control
Solution Approach 2:
The patent replaces slow manual sequential placement with automated robotic placement guided by optical detection and electronic processing. The system rapidly detects object positions, calculates deviations, and controls the placement tool to position objects automatically, dramatically increasing productivity while keeping the control logic simple
4Manufacturing precision
If exact alignment of optical line with objects is required, then positioning precision is improved, but the placement process becomes more time-consuming and complex
Solution Approach 1:
The patent introduces an intermediary computational step where the processing device calculates the deviation between the optical line and the line of sight connecting detected objects. This intermediary calculation allows the system to work with approximate alignments and mathematically determine the correct placement position, eliminating the need for time-consuming exact manual alignment while maintaining high precision
Solution Approach 2:
The patent changes the approach from requiring exact geometric alignment to calculating positional deviation as a measurable parameter. By transforming the alignment problem into a deviation calculation problem, the system can tolerate approximate initial alignments and achieve precise positioning through computational correction, reducing alignment time

AI summary
A method and system for placing at least one object on a surface, the object being carried and positioned by a tool. The method comprises determining a deviation in at least one dimension between a line of sight between a first and a second object placed on the surface and an optical line directed from the first towards the second object, determining a position in at least one dimension for the tool based on the determined deviation, and positioning the tool so that the position is achieved, thereby placing the object on the surface.
