Rotatable Display Frame Thickness Reduction via Wedging Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotatable LCDs face a design constraint where the hook required to secure the display module after rotation increases the frame thickness, contradicting miniaturization trends in electronic products.
Innovation Solution
The design incorporates a frame with concave blocking parts and wedging structures on the display module edges, allowing the display module to rotate without a traditional hook, thereby reducing the frame thickness and enabling miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hook is used to fasten the display module after rotation, then the display module can be securely fastened, but the frame thickness increases
Solution Approach 1:
The patent extracts the fastening function from a traditional hook structure and relocates it to the display module itself through protrusions that engage with grooves in the frame. This removes the need for a separate hook component, thereby reducing frame thickness while maintaining secure fastening capability.
Solution Approach 2:
Instead of having the frame provide the fastening mechanism (hook), the invention inverts the approach by placing the fastening protrusions on the display module. This reversal allows the display module to actively engage with the frame structure, achieving secure fastening without requiring the frame to have thick hook structures.
2Length of stationary object
If the frame thickness is reduced for miniaturization, then the electronic apparatus size decreases, but the ability to securely fasten the rotatable display module is compromised
Solution Approach 1:
The fastening protrusions are integrated into the display module structure itself, nesting the fastening function within the existing display module geometry. This eliminates the need for separate fastening components that would increase frame thickness, allowing miniaturization while maintaining secure attachment through the protrusion-groove engagement mechanism.
3Reliability
If a traditional hook structure is used, then the display module can be fastened, but the device complexity increases
Solution Approach 1:
The patent merges the fastening function with the display module structure by integrating protrusions directly onto the display module. This combines two previously separate functions (display module housing and fastening mechanism) into a single integrated component, reducing overall device complexity while maintaining secure fastening capability.

AI summary
An electronic apparatus includes a frame, at least one first blocking part, at least one second blocking part, a display module, a first wedging structure and a second wedging structure. The frame includes a first frame stick, a second frame stick and a third frame stick connecting the first frame stick and the second frame stick. The first blocking part is disposed on the first frame stick. The second blocking part is disposed on the second frame stick. The display module includes a first edge, a second edge and at least one third edge. The third edge is pivotally connected to the third frame stick. The first and second wedging structures are respectively disposed on the first and second edges for wedging the first blocking part or the second blocking part. The first wedging structure and the second wedging structure are misaligned.
