Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an edge holder strip is placed across an edge of the print target and fixed to opposing ends of the platen, then the print target can be held in place, but the print target deforms during the printing process due to inadequate holding mechanisms
Solution Approach 1:
The tensioner device incorporates an adjustable fixing mechanism with threaded holes and receiving holes that allow dynamic adjustment of the holding force. The mechanism can be tightened or loosened to apply appropriate tension to the edge holder strip, adapting to different print target sizes and materials to prevent deformation while maintaining secure holding.
Solution Approach 2:
The invention changes the physical parameter of tension force by introducing a tensioning mechanism with threaded adjustment. This allows the holding force to be increased from a static fixed state to a dynamically adjustable state, enabling optimal tension application that prevents print target deformation during the printing process.
2Device complexity
If a simple edge holder strip is used to hold the print target, then the device complexity is low, but the printing precision deteriorates due to print target deformation and misalignment
Solution Approach 1:
The holding mechanism is segmented into distinct functional components: the edge holder strip for basic positioning, the tensioner device for force application, and the adjustable fixing mechanism for securing. This segmentation allows each component to perform its specific function optimally while maintaining overall system manageability and precision.
Solution Approach 2:
The tensioner device acts as an intermediary between the fixed platen structure and the edge holder strip. It mediates the force transmission by providing an adjustable mechanical advantage through its threaded mechanism, enabling precise control over the tension applied to the print target edge, thereby improving printing accuracy without excessive complexity.
3Stability of the object's composition
If the edge holder strip is tightly fixed to prevent deformation, then the print target stability improves, but the adjustment flexibility and ease of operation deteriorates
Solution Approach 1:
The fixing mechanism transitions from a static tight fixation to a dynamic adjustable system. The threaded holes and receiving holes enable the user to adjust the tension level according to different requirements, allowing both stable fixing and operational flexibility. The mechanism can be easily tightened or loosened as needed.
Solution Approach 2:
The invention applies partial tensioning rather than maximum fixed tension. The adjustable mechanism allows applying just enough force to prevent deformation without over-tightening, which would reduce adjustment flexibility. This partial action approach maintains both stability and operability.

AI summary
A tensioner device for use with a printing device is described which is to hold an end of a print target holder sheet in a substantially planar configuration across a platen of a printing device. The tensioner device can be fixed to a frame attachable to a platen of a printing device. The tensioner device has a first surface, and the frame has a second surface corresponding to the first surface. The first surface is formed to slide along the second surface in a first direction having an oblique angle with respect to a plane of the print target holder sheet. A fixing mechanism is also described which allows the first surface to be fixed to the second surface at different positions along the first direction. An apparatus including the tensioner device and the frame is also described. A system including a printer, a platen, tensioner devices and frames is also described.
