Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional casing structures with frames and frame pieces are used, then edge protection is provided, but manufacturing cost increases due to precise machining requirements and skilled labor
Solution Approach 1:
The patent applies a flexible elastic jacket instead of rigid frames. The elastic jacket is made of elastic material that can deform to accommodate substrate expansion and contraction, eliminating the need for precise machining while providing continuous edge protection. This flexible approach reduces manufacturing complexity and cost compared to conventional rigid frame structures.
Solution Approach 2:
The patent changes the material parameter from rigid to elastic, allowing the casing to dynamically adapt to dimensional changes of the substrate. This parameter change enables the jacket to maintain proper fit and protection without requiring precise manufacturing tolerances, thereby reducing manufacturing cost while maintaining reliability.
2Shape
If soft frames are used for aesthetic appearance, then appearance is improved, but the frame peels off due to substrate expansion and contraction
Solution Approach 1:
The elastic jacket is designed as a flexible shell that inherently accommodates substrate thermal expansion and contraction through its elastic properties. This flexibility prevents peeling while maintaining aesthetic appearance, as the jacket conforms to the substrate's dimensional changes without detaching.
Solution Approach 2:
The patent introduces dynamic adaptability through the elastic material that can change its shape and dimensions in response to substrate expansion and contraction. This dynamic behavior maintains reliable attachment while preserving aesthetic appearance, overcoming the limitation of static soft frames that peel when substrate dimensions change.
3Stability of the object's composition
If rigid frames are used for precise assembly, then structural stability is maintained, but assembly complexity increases requiring skilled operators
Solution Approach 1:
The flexible elastic jacket simplifies assembly by eliminating the need for precise alignment and complex fastening mechanisms required by rigid frames. The elastic material naturally conforms to the substrate shape, allowing simple attachment without skilled operators while maintaining structural stability through continuous elastic support.
Solution Approach 2:
The elastic jacket can be applied as a continuous flexible layer rather than assembling multiple rigid components, reducing assembly steps and complexity. This segmented approach allows the jacket to be positioned and secured in a single operation, eliminating the need for skilled assembly operators required by multi-component rigid frame structures.

AI summary
The present invention has an object to provide a planar light-emitting panel attached with a jacket to protect edges of a light-emitting tile, while the jacket is prevented from being peeled off or removed from the light-emitting tile. The planar light-emitting panel includes the light-emitting using a glass substrate as a base, and an elastic jacket covering end faces of the glass substrate. An emission surface is provided on a front face of the light-emitting tile. The elastic jacket has a rear face side opening, on a rear face side of the light-emitting tile. On opening edges of the rear face side opening, when viewed from rear, a plurality of jacket side protrusions protruding toward a center side of the rear face side opening are formed. The jacket side protrusions are separated at predetermined intervals along the opening edges.
