Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional side guides and pushing plates are used to adjust the preset angle of the rolling piece, then the structure is simple, but the adjustment speed is slow and the accuracy is low
Solution Approach 1:
The patent replaces the conventional mechanical side guides and pushing plates with a laser lineation positioning device that uses optical fields instead of mechanical contact. The laser emitter projects reference lines onto the rolling piece to indicate the preset angle position, eliminating the need for complex mechanical adjustment mechanisms while significantly improving measurement precision and response speed.
Solution Approach 2:
The patent introduces laser reference lines as an intermediary visual indicator between the positioning system and the rolling piece. These laser lines serve as a mediator that provides intuitive visual feedback to operators about the preset angle position, enabling rapid and accurate angle adjustment without direct mechanical intervention.
2Speed
If conventional side guides are used for angle adjustment, then the device complexity is low, but the reaction speed is slow and adjustment time is long
Solution Approach 1:
The patent replaces slow mechanical adjustment mechanisms with an optical laser positioning system that can instantly project reference lines at any desired angle. This substitution eliminates mechanical inertia and friction, enabling rapid response and real-time angle adjustments without the delays inherent in conventional mechanical systems.
Solution Approach 2:
The patent pre-calculates and stores preset angle data in advance, allowing the laser positioning device to instantly project the correct reference lines when needed. This preliminary preparation of angle information enables immediate positioning without requiring real-time calculation or complex mechanical adjustments during the rolling process.
3Loss of information
If conventional mechanical positioning is used, then the structure is simple, but workers cannot intuitively and accurately acquire whether the rotation angle meets preset requirements
Solution Approach 1:
The patent uses the visible light properties of laser beams to create bright, high-contrast reference lines that are easily visible against the rolling piece background. This optical visualization method provides intuitive visual feedback that immediately communicates the preset angle position to workers, eliminating the information loss associated with conventional mechanical indicators.
Solution Approach 2:
The laser reference lines serve as an information intermediary that translates complex angular measurements into simple, intuitive visual indicators. Workers can directly observe the laser lines' position relative to the rolling piece to determine whether the rotation angle meets requirements, providing clear and immediate feedback without requiring complex measurement instruments.
