Portable Electronic Module Back Cover Detachable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration for portable electronic modules makes it time-consuming and strenuous to replace the back cover, as it requires disassembling the bezel, liquid crystal module, and related components, making the process difficult and inflexible.
Innovation Solution
A design where the glass panel device, limiting members, backlight device, and related components are assembled onto the bezel sequentially, allowing the back cover to be detachably connected, enabling quick replacement without disassembling other components by using a pivotally connected shaft member and screw-locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the back cover is assembled with the bezel, liquid crystal module, and related components in a conventional configuration, then the structural integrity and protection function are maintained, but the back cover replacement process becomes time-consuming and strenuous requiring disassembly of multiple components
Solution Approach 1:
The device is divided into modular components where the back cover is separately detachable from the bezel and internal components. The bezel with glass panel device and backlight device forms one module, while the back cover is a separate replaceable module, allowing independent replacement without disassembling other parts.
Solution Approach 2:
The back cover is extracted as a separate replaceable component from the integrated assembly. By removing the back cover from the conventional integrated structure, the patent enables users to replace only the back cover without needing to disassemble the bezel, liquid crystal module, or other internal components.
2Reliability
If the back cover is integrated with the bezel and liquid crystal module in a conventional configuration, then the protection function is maintained, but the ease of replacement is reduced making the process difficult and inflexible
Solution Approach 1:
The device structure is segmented into distinct modules: the bezel module containing the glass panel device and backlight device, and the back cover module. This segmentation maintains the protection function while enabling independent replacement of the back cover without affecting other components.
Solution Approach 2:
The back cover is designed with dynamic replaceability through detachable connections to the bezel. The shaft member with pivot portion enables the back cover to be easily attached and detached, providing operational flexibility while maintaining structural integrity during use.
3Reliability
If the back cover is assembled with multiple components in a conventional configuration, then the structural integrity is maintained, but the device complexity increases making the assembly and disassembly process more complex
Solution Approach 1:
The device is divided into simplified modules where the bezel with internal components is one unit and the back cover is another unit. This segmentation reduces assembly complexity by eliminating the need to disassemble multiple components when replacing the back cover, while maintaining structural integrity through proper connection interfaces.
Solution Approach 2:
The bezel serves multiple functions: it contains the glass panel device, backlight device, and provides connection interfaces for the back cover. This multi-functionality simplifies the overall structure by consolidating components into a single modular unit that can be easily assembled and disassembled.

AI summary
A portable electronic module includes a bezel, a glass panel device, a first limiting member, a backlight device, a second limiting member, and a back cover. The glass panel device is fixed onto the bezel. The first limiting member is disposed at a first side of the glass panel device. The backlight device is disposed on the glass panel device. The second limiting member is disposed at a second side of the glass panel device for limiting the backlight device cooperatively with the first limiting member. The back cover covers the backlight device and is detachably connected to the bezel for containing the glass panel device and the backlight device cooperatively with the bezel.
