Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display apparatus is mounted on a movable apparatus to enable convenient use, then ease of operation is improved, but the display apparatus becomes vulnerable to external impacts causing damage and malfunction
Solution Approach 1:
The fastening hole is designed with an asymmetric structure where the diameter in the first direction (impact direction) is greater than the diameter in the second direction. This allows the protrusion to move freely in the first direction when subjected to external impact, while maintaining stable fastening in the second direction. The dynamic movement capability absorbs impact energy and prevents damage to the display apparatus.
Solution Approach 2:
The fastening hole's geometric parameters are specifically designed with different diameters in different directions. The diameter in the first direction is made larger to allow movement and absorb impact, while the diameter in the second direction is smaller to maintain secure fastening. This parameter variation enables the structure to simultaneously achieve stable mounting and impact resistance.
2Weight of moving object
If the display apparatus has a slim or flexible structure to reduce size and weight, then ease of operation and portability are improved, but the effect of external impact is amplified causing greater damage risk
Solution Approach 1:
The asymmetric fastening hole design provides a dynamic response mechanism that is particularly important for slim and flexible display apparatus. When impact occurs, the protrusion can move within the enlarged first direction diameter, allowing the lightweight structure to absorb impact energy through movement rather than rigid resistance, thereby preventing damage.
Solution Approach 2:
The fastening hole structure is designed in advance to accommodate impact forces. The larger diameter in the first direction creates a built-in cushioning mechanism that allows the protrusion to move and absorb impact energy before it can damage the slim or flexible display apparatus structure.
3Reliability
If the protrusion is designed to move in response to external impact to absorb force, then durability is improved, but the fastening stability may be compromised
Solution Approach 1:
The fastening hole is designed with different diameters in different directions, creating local quality variations. In the first direction (impact direction), the larger diameter allows movement for durability. In the second direction (perpendicular to impact), the smaller diameter maintains tight fastening stability. This directional differentiation resolves the contradiction between movement and stability.
Solution Approach 2:
The asymmetric fastening hole structure has different diameters along different axes. This asymmetry enables the protrusion to move freely in the first direction when impacted, while maintaining stable fastening in the second direction. The asymmetric design simultaneously achieves both durability through movement and stability through constrained fastening.

AI summary
A display apparatus includes a display panel; and a rear cover coupled to a rear face of the display panel to support the display panel, the rear cover includes a protrusion protruding from the rear cover and including a fastening hole defined therein and fastened with coupling means, and the length of the fastening hole in a first direction is greater than a length of the fastening hole in a second direction orthogonal to the first direction. In the display apparatus, the protrusion moves in response to an external force, so that the display apparatus having the protrusion can effectively absorb the external impact to suppress damage to the display apparatus.
