Side-Locking Liquid Crystal Display Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display devices require a significant space for screw pillars or latches, increasing production costs and device size, which contradicts the goal of creating light, thin, short, and small devices.
Innovation Solution
The design incorporates a panel with side locking holes and frames with matching slots and hooks, eliminating the need for external fastening elements by locking components from the side edge, reducing the overall space required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw pillars or latches are used to lock the front frame with the panel or back lid, then the assembly reliability is improved, but the device size and production cost increase
Solution Approach 1:
The locking function is merged into the side edge structure itself. The side edge integrates both the locking hole and the slot directly into its body, eliminating the need for separate screw pillars or latches. This merging of functions reduces the overall device size while maintaining assembly reliability through the integrated locking mechanism.
Solution Approach 2:
The locking mechanism is extracted from a separate component (screw pillar or latch) and integrated directly into the side edge structure. By taking out the need for external fastening elements and embedding the locking functionality within the frame's side edge, the device size is reduced while preserving the reliability of the connection.

3Reliability
If a greater distance is reserved between the panel outer frame and the front frame surface, then the assembly reliability is improved, but the device size increases
Solution Approach 1:
The locking mechanism transitions from a protruding external structure (screw pillars extending outward) to an integrated side-edge structure. By moving the locking function to the side edge dimension rather than requiring external protrusions, the distance between components is minimized while maintaining reliable assembly through the integrated locking holes and slots.

AI summary
A liquid crystal display device is disclosed. The liquid crystal display device includes a panel, a first frame, and a second frame. The panel has a side face. At least one first locking hole is disposed on the side face. The first frame includes a first side edge and a second side edge. The first side edge has at least one second locking hole and at least one slot. The at least one first locking hole and the at least one second locking hole are locked with each other via at least one locking element, so as to fix the panel and the first frame. The second frame has at least one hook part used for matching the at least one slot of the first side edge such that the second frame and the first frame can be fixed to each other.
