Solution Overview
Problem
Conventional backlight modules face difficulties in assembly and disassembly due to numerous sets of insecure mounting member-slot assemblies, leading to low productivity and a high risk of broken screens from dislodging, along with elevated manufacturing costs due to precision requirements.
Innovation Solution
A snap-fit assembly structure using cantilever beams between the back cover and frame, allowing for secure and removable engagement with reduced complexity and precision needs, featuring 4-8 sets of snap-fit connections, which simplifies assembly and disassembly while minimizing dislodging risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If numerous sets of mounting member-slot assembly are used to secure the frame to the back cover, then the connection reliability is improved, but the device complexity and assembly difficulty increase significantly
Solution Approach 1:
The mounting connection is segmented into two functional parts: the mounting slot in the back cover and the mounting member on the frame. The mounting member includes a body portion and a snap member that can elastically deform to engage with the slot, allowing secure connection through multiple segments working together.
Solution Approach 2:
The snap member is designed with elastic deformation capability, allowing its shape and position parameters to change during assembly. When the frame is assembled onto the back cover, the snap member elastically deforms to pass through the mounting slot and then snaps into place, providing secure connection with reduced assembly complexity.
2Reliability
If numerous sets of mounting member-slot assembly are used to secure the frame, then the connection reliability is improved, but the productivity decreases due to tedious assembly and disassembly operations
Solution Approach 1:
The snap member is designed to automatically engage with the mounting slot through elastic deformation without requiring additional fastening operations. During assembly, the snap member self-adjusts its position and shape to secure the frame to the back cover, eliminating the need for screws or clips and significantly improving productivity.
Solution Approach 2:
The snap member incorporates dynamic elastic deformation capability, allowing it to flex during assembly and disassembly operations. This dynamic behavior enables quick engagement and release of the frame from the back cover, reducing assembly time and improving productivity while maintaining secure connection.
3Device complexity
If traditional mounting member-slot assembly is used, then the structure is simple, but the connection reliability is insufficient causing local dislodging and potential screen damage
Solution Approach 1:
The mounting member is constructed as a composite structure combining a rigid body portion for structural support and an elastic snap member for secure engagement. This composite design maintains overall structural simplicity while providing reliable connection through the elastic-deformation mechanism of the snap member.
Solution Approach 2:
The snap member features a curved or arc-shaped engagement surface that complements the mounting slot geometry. This curved design allows the snap member to smoothly deform and lock into the slot, distributing mechanical stress evenly and preventing local dislodging that could damage the screen.
4Ease of manufacture
If traditional mounting member-slot assembly is used, then the manufacturing process is straightforward, but the manufacturing precision requirements are elevated increasing quality control costs
Solution Approach 1:
The snap member's elastic properties allow it to accommodate variations in mounting slot dimensions through deformation. This parameter change capability reduces the stringency of size match requirements between the mounting member and slot, lowering manufacturing precision requirements and quality control costs while maintaining ease of manufacture.
