Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display assembly techniques, such as those involving angular U-shaped frames, complicate the assembly process and lead to component breakage due to interference during assembly.
Innovation Solution
A display configuration featuring a front frame, a backlight with a back and middle frame, a circuit board, and a protective cover with abutment and butted portions that facilitate secure fitting without interference, ensuring precise assembly and preventing component breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If angular U-shaped frames are used for fixation, then fixation strength is improved, but assembly complexity increases and component breakage occurs
Solution Approach 1:
The frame structure is divided into multiple segments: front frame, back frame, and middle frame. Each frame has specific functions and can be assembled independently, reducing overall assembly complexity while maintaining fixation strength through distributed connection points
Solution Approach 2:
The middle frame acts as an intermediary component between the front frame and back frame. It provides a buffer zone that prevents direct interference between opposing components during assembly, reducing breakage risk while maintaining structural integrity
2Manufacturing precision
If components are tightly fitted for precision, then manufacturing precision is improved, but assembly difficulty increases
Solution Approach 1:
The frames incorporate asymmetric features such as protrusions on one side and corresponding recesses on the opposite side. This asymmetric design provides built-in alignment guidance that simplifies the assembly process while ensuring precise positioning of components
Solution Approach 2:
Alignment protrusions and recesses are pre-formed on the frames before assembly. These preliminary structural features guide the components into correct positions during assembly, eliminating the need for complex alignment procedures and reducing assembly difficulty

AI summary
Provided is a display that facilitates assembly, and prevents breakage in its components resulting from their interference during the assembly. A display includes a shield cover that has a bottom portion and a side portion. The bottom portion is disposed over a circuit board. The side portion is continued to the bottom portion, and faces the outer surface of one side of the side portion of a middle frame. The side portion of the shield cover has an abutment portion protruding toward the middle frame side. The one side of the side portion of the middle frame has a butted portion that abuts on abutment portion. The shield cover and the middle frame are fixed to each other, by fitting the shield cover into the front frame with the abutment portion of the shield cover brought into abutment with the butted portion of the middle frame.
