Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual shaping process is used, then flexibility and adaptability are maintained, but time consumption increases and precision deteriorates
Solution Approach 1:
The patent replaces manual mechanical shaping operations with an automated system that uses optical sensing (non-contact measurement) combined with computer-controlled pressing mechanisms. The sensing module captures surface information optically, the calculation module processes this data to determine shaping parameters, and the pressing module applies controlled mechanical force automatically, eliminating manual intervention while achieving both high precision and efficiency
Solution Approach 2:
The system implements self-service through automatic feedback control. The sensing module continuously monitors the workpiece surface, the calculation module automatically compares measured data with target specifications, and the pressing module autonomously adjusts pressing forces and positions based on calculated deviations, enabling the system to self-correct and achieve precise shaping without human intervention
2Adaptability or versatility
If one-dimensional or two-dimensional shaping apparatus is used, then device complexity is reduced, but shaping capability for three-dimensional workpieces deteriorates
Solution Approach 1:
The patent transitions from traditional one-dimensional or two-dimensional pressing mechanisms to a three-dimensional pressing system. The pressing module incorporates multi-axis movement capabilities (X, Y, and Z directions) with independent control of pressing positions and forces in three-dimensional space, enabling comprehensive shaping of complex 3D workpiece surfaces that cannot be achieved with conventional planar apparatus
Solution Approach 2:
The system achieves versatility through a modular design where the sensing module, calculation module, and pressing module work together as an integrated multi-functional platform. The same apparatus can handle various workpiece types and shaping requirements by loading different target shape data and adjusting pressing parameters, making it universally applicable to diverse three-dimensional shaping tasks
3Manufacturing precision
If human visual aided judgment is used, then adaptability to different workpieces is maintained, but reliability and precision deteriorate
Solution Approach 1:
The patent replaces human visual judgment with optical sensing technology. The sensing module uses non-contact optical methods to capture precise surface information of the workpiece, eliminating the subjectivity and limitations of human vision. This optical measurement system provides objective, repeatable, and highly precise data for shaping control
Solution Approach 2:
The system implements closed-loop feedback control where the sensing module measures actual surface positions, the calculation module compares these measurements with target specifications to determine deviations, and the pressing module applies corrective forces based on this feedback. This continuous measurement-correction cycle ensures high precision and reliability by constantly monitoring and adjusting the shaping process
