Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of control items is implemented, then UV irradiation precision is improved, but user operation burden increases
Solution Approach 1:
The system automatically determines UV irradiation parameters by self-adjusting based on stored correlation data between control items and UV intensity values, eliminating the need for manual user adjustment while maintaining precise irradiation control
Solution Approach 2:
The control device stores correlation data between control items and UV irradiation values, and uses this stored information to automatically determine appropriate UV intensity settings based on the selected control item values, creating a feedback loop that maintains precision without manual intervention

AI summary
A sheet embellishing system performs embellishment on a sheet while conveying the sheet. The sheet embellishing system includes a varnish-applying unit that applies varnish having ultraviolet (UV) curability onto the sheet, a UV irradiation unit that irradiates the varnish on the sheet by UV rays, and a control device. The control device acquires, from a storage unit that stores adhesivity-related information that is information relating to adhesivity between the varnish on the sheet and a transfer material that is to be transferred into the varnish on the sheet, and a value regarding a control item of the sheet embellishing system, in a correlated manner, a value of the control item of which the adhesivity-related information corresponds to the adhesivity-related information of a current job, and executes predetermined processing using the value of the control item that is acquired.
