Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If electromagnetic waves are used to distend the sheet for forming three-dimensional images, then the shaped object can be produced with three-dimensional structure, but the temperature environment cannot be controlled leading to uneven distension and low precision
Solution Approach 1:
The sheet is preheated by heaters before electromagnetic wave irradiation to a predetermined temperature. This preliminary heating action ensures that the sheet reaches the optimal temperature for uniform distension before the shaping process begins, thereby improving manufacturing precision by eliminating temperature-related unevenness in the three-dimensional image formation.
Solution Approach 2:
The temperature of the sheet is controlled as a critical parameter by heating it to a predetermined temperature before electromagnetic wave irradiation. By changing and controlling the temperature parameter in advance, the sheet achieves uniform distension characteristics, which directly improves the precision of three-dimensional image formation while resolving the temperature control issue.
2Shape
If the sheet is irradiated with electromagnetic waves to cause distension, then three-dimensional shapes can be formed, but uneven distension occurs due to lack of temperature control
Solution Approach 1:
The sheet is preheated to a predetermined temperature before electromagnetic wave irradiation. This preliminary heating ensures that the entire sheet reaches a uniform temperature state, which stabilizes the distension characteristics and prevents unevenness during the three-dimensional shape formation process.
Solution Approach 2:
The temperature parameter of the sheet is controlled and maintained at a predetermined value before irradiation. By stabilizing this critical parameter, the sheet exhibits consistent distension behavior across different regions, ensuring uniformity in the final three-dimensional shape and improving compositional stability.
3Extent of automation
If electromagnetic waves are used for shaping, then the process can be automated, but temperature-related instability reduces production reliability
Solution Approach 1:
A temperature sensor detects the actual temperature of the sheet, and this feedback information is used by the control unit to adjust the heating process. By implementing feedback control, the system automatically maintains the sheet at the predetermined temperature, ensuring stable and reliable three-dimensional shape formation while preserving the automation of the process.
Solution Approach 2:
Manual temperature control is replaced by an automated system comprising heaters, temperature sensors, and a control unit. This substitution of mechanical/manual operations with an automated control system improves both the extent of automation and the reliability of shape formation by eliminating human error and maintaining consistent temperature conditions.
