Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the woven screen is made taut in both directions to prevent wrinkles and improve appearance, then the aesthetic appearance is improved, but the screen becomes susceptible to permanent deformation when repeatedly removed and inserted
Solution Approach 1:
The patent applies different adhesion strengths in different directions by using fibers with varying adhesion properties oriented in specific directions. The first set of fibers has a first adhesion strength while the second set has a second adhesion strength, creating local quality variations that allow the screen to maintain shape in one direction while accommodating movement in another direction during installation and removal.
2Ease of operation
If excessive force is applied to remove and insert the woven screen, then the screen can be installed and removed, but damage occurs to the woven screen and frame
Solution Approach 1:
The patent changes the adhesion parameter by using fibers with different adhesion strengths oriented in different directions. This allows the screen to be easily installed and removed by applying force in the direction where fibers have lower adhesion strength, while the higher adhesion strength fibers maintain structural integrity and prevent damage during the process.
3Stability of the object's composition
If the screen is made rigid to maintain shape, then the structural stability is improved, but the screen becomes difficult to install and remove without deformation
Solution Approach 1:
The patent creates local quality differences by orienting fibers with different adhesion strengths in different directions. This allows the screen to exhibit rigid behavior in directions where high adhesion fibers are oriented, maintaining shape stability, while allowing easier installation and removal in directions where low adhesion fibers are oriented, reducing resistance during operational movements.

AI summary
An insect screen including: a frame, wherein the frame has a flexible response when a pressure is applied to the frame and maintains a rigid shape when secured in a building opening; and an open mesh substrate attached to the frame, wherein the open mesh substrate comprises a set of first fibers oriented in a first direction of said open mesh substrate, wherein the set of first fibers has a first adhesion strength to the frame; and a set of second fibers oriented in a second direction that is perpendicular to the first direction, wherein the set of second fibers has a second adhesion strength to the frame, wherein the second direction is perpendicular to the first direction, wherein the first set of fibers and the second set of fibers are configured to intersect, and wherein the first adhesion strength is greater than the second adhesion strength.
