Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If protrusions are bent to form adhesive materials covering sharp angles, then the print screen unit can be assembled without additional connection members, but manufacturing time and cost increase due to multiple cutting and bending operations
Solution Approach 1:
The connection member is divided into a flat plate portion and a protrusion portion that are formed separately and then assembled together. This segmentation allows each part to be manufactured independently using simpler processes, avoiding the need for complex multi-step cutting and bending operations while still achieving the same functional result of covering sharp angles and enabling assembly.
2Device complexity
If protrusions are bent to form adhesive materials, then additional connection members are not required, but workers may be harmed by sharp edges during assembly
Solution Approach 1:
By separating the connection member into a flat plate portion and a protrusion portion, the sharp edges are confined to the protrusion portion which is inserted into the print screen first. The flat plate portion with safer edges is then attached to the interface unit, reducing the risk of worker injury during assembly while maintaining the integrated connection function.
3Reliability
If the print screen is attached to the support frame using adhesive, then the print screen is already attached when required, but the support frame becomes heavy and large when not in use
Solution Approach 1:
The connection member is designed to be detachably connected between the print screen and the support frame. This dynamic connection allows the print screen to be easily attached when needed and removed when not in use, preventing the support frame from constantly bearing the weight of an unused print screen while maintaining reliable attachment during use through the engineered connection interface.
4Weight of stationary object
If the print screen is removed from the support frame for storage, then the support frame weight is reduced, but the thin print screen is difficult to keep without damaging printing patterns
Solution Approach 1:
The detachable connection member enables controlled removal and reattachment of the print screen. When removal is necessary for storage or transport, the engineered connection interface ensures the print screen can be handled safely without bending or damaging the thin material and precise printing patterns, while allowing the support frame to be lighter when the print screen is not in use.
5Ease of manufacture
If conventional connection structures are used, then assembly is simple, but coupling force decreases when tensile force is applied, causing deformation and damage
Solution Approach 1:
The protrusion portion is pre-formed with a shape and structure optimized for engaging with the interface unit's recess. This preliminary formation ensures that when tensile force is applied to the print screen, the coupling force is immediately activated through the pre-configured geometric interlocking, preventing deformation and damage while maintaining assembly simplicity.
Solution Approach 2:
The protrusion portion is formed with curved surfaces that complement the recess shape in the interface unit. This curved geometry creates a more effective coupling that distributes tensile forces more evenly across the connection interface, increasing coupling strength and preventing the deformation and damage associated with conventional straight-edged connections.

AI summary
A print screen unit of the present invention: can minimize the loss of the materials and reduce manufacturing costs and time so as to lower production costs; has a structure in which the connection member is positioned to be slanted at a predetermined angle when the print screen is fitted to an interface unit, such that, as tensile force is applied to the print screen, the engagement state of engaging apertures of the print screen and engaging protrusions of the connection member moves toward the coupling direction thereof so as to further increase coupling force therebetween; and has a structure in which, when each of corner pieces is fitted into and connected to each of end portions of the interface unit, a connection surface area increases so as to bring three surfaces of the inside of the interface unit into close contact with a first and a second piece member.
