Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices require fastening members like screws for coupling stands to back covers, which complicates assembly, disassembly, and stability.
Innovation Solution
A display device design where a stand is detachably coupled to a back cover using hooks and holes without the need for screws, enhancing coupling stability and ease of assembly/disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fastening members like screws are used to couple the stand to the back cover, then the coupling strength is improved, but the device complexity and ease of assembly/disassembly deteriorate
Solution Approach 1:
The coupling structure is divided into separate functional elements: the stand includes a body, head, and arms with hooks, while the back cover includes a coupling portion with holes. This segmentation allows each component to be optimized independently and simplifies assembly by eliminating the need for separate fastening members like screws.
Solution Approach 2:
The head of the stand is inserted into the coupling portion of the back cover, creating a nested structure where the head fits within the coupling portion. The arms with hooks are positioned within the body structure, providing a compact integrated design that eliminates external fasteners.
2Reliability
If fastening members like screws are used to couple the stand to the back cover, then the coupling stability is improved, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The coupling structure is designed to be self-assembling through the interaction of the head inserting into the coupling portion and the hooks engaging with the holes. The structure provides its own fastening mechanism without requiring external tools or additional fastening members, making assembly simple while maintaining stability.
3Reliability
If a complex fastening system is used to couple the stand to the back cover, then the coupling stability is improved, but the productivity of assembly process deteriorates
Solution Approach 1:
The coupling structure is divided into separate functional elements: the stand includes a body, head, and arms with hooks, while the back cover includes a coupling portion with holes. This segmentation allows each component to be optimized independently and simplifies assembly by eliminating the need for separate fastening members like screws.

AI summary
A display device may include a display panel, a back cover located at the rear of the display panel, and a stand coupled to the back cover, wherein the stand may include a body, a head protruding into the back cover from an upper end of the body, a first arm extending downward from one side of the top of the head, and a second arm extending downward from the other side of the top of the head, the back cover may include a coupling portion protruding into the back cover from the lower side of the back cover, and the coupling portion may include a first hole formed in a side surface of the coupling portion, the first hole allowing a first hook to be caught therein, and a second hole opposite the first hole, the second hole allowing a second hook to be caught therein.
