Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional multi-step measurement methods are used to measure hollow components, then measurement completeness may be achieved, but measurement time increases and real-time feedback is lost
Solution Approach 1:
The patent combines multiple measurement operations into a single measuring step by positioning the scanning device inside the first hollow component to simultaneously scan both components. This merging of measurement actions achieves real-time data acquisition without sacrificing alignment precision, directly resolving the contradiction between measurement speed and precision.
Solution Approach 2:
The patent transitions from external multi-step measurement to internal single-step measurement by placing the scanning device inside the first hollow component. This dimensional change in measurement approach enables simultaneous scanning of both components, achieving both speed and precision requirements.
2Ease of operation
If hollow components are measured from external positions, then access is easier, but measurement precision and alignment accuracy deteriorate
Solution Approach 1:
The patent inverts the traditional external measurement approach by positioning the scanning device inside the first hollow component. This inversion enables direct, precise measurement of the joining area from the internal position, achieving both accessibility and high measurement accuracy simultaneously.
Solution Approach 2:
The scanning device acts as an intermediary positioned inside the first hollow component, enabling precise measurement of the joining area without requiring external access. This intermediary positioning resolves the contradiction between ease of operation and measurement precision.
3Loss of information
If multiple measuring steps are used to scan both hollow components, then comprehensive data is obtained, but measurement time increases and real-time feedback is lost
Solution Approach 1:
The patent merges the scanning of both hollow components into a single measuring step by positioning the scanning device internally, allowing simultaneous data acquisition from both components. This eliminates the need for multiple measuring steps, preventing both information loss and time loss.
Solution Approach 2:
The patent enables continuous measurement action by scanning both components in one step from the internal position, maintaining uninterrupted data acquisition. This continuity prevents loss of measurement information and eliminates time delays associated with multiple discrete measuring steps.
4Device complexity
If dimensionally unstable hollow components are joined without real-time measurement, then the process is simpler, but joint precision and long-term stability deteriorate
Solution Approach 1:
The patent implements real-time feedback by scanning the joining area of dimensionally unstable components during the alignment process and using the measured data to adjust positioning. This feedback mechanism ensures high joint precision despite component instability, resolving the contradiction between system complexity and manufacturing precision.
Solution Approach 2:
The patent performs preliminary scanning and measurement of the joining area before final assembly, allowing alignment adjustments to be made in advance. This preliminary action ensures precise joint formation despite component dimensional instability, balancing system complexity with manufacturing precision.
