Rotating Support Lever for Portable Device Battery Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices pose a risk of user injury and damage to the back cover when attempting to replace the battery due to the small size of the latch required for detachment.
Innovation Solution
A portable electronic device design featuring a rotatable supporting unit that allows for easy separation of the casing from the main body without requiring direct force application, using a pivotally connected mechanism that supports the main body and facilitates detachment by rotating to a second position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a small latch is used to fasten the back cover, then the device structure is compact and simple, but the user may get injured or damage the back cover due to inappropriate force application
Solution Approach 1:
The patent introduces a lever arm as an intermediary tool between the user's finger and the latch. This lever arm provides a larger surface area for force application, allowing users to open the back cover without directly pressing the small latch with their fingers, thereby eliminating the risk of injury or damage while maintaining the compact latch structure.
2Ease of operation
If direct force is applied to the latch to separate the back cover, then the detachment process is simple, but the user may cause injury or damage due to the small size of the latch
Solution Approach 1:
The lever arm serves as a mediator that transforms the user's finger motion into effective latch opening force. By placing the lever arm on the latch and rotating it, users can easily separate the back cover without directly applying force to the small latch, thus maintaining ease of operation while preventing injury and damage.
3Object-affected harmful factors
If the latch size is increased to make it easier to operate, then user safety improves, but the device structure becomes more complex and space-consuming
Solution Approach 1:
The patent divides the fastening system into two independent components: a compact latch structure for fastening and a separate lever arm tool for opening. This segmentation allows the latch to remain small and simple while the lever arm provides the necessary operational safety, avoiding the need to increase latch size and maintaining device compactness.

AI summary
A portable electronic device includes a main body, a casing and a supporting unit. The casing is detachably connected to the main body. The supporting unit is connected to the casing and is rotatable relative to the casing. When the supporting unit rotates to a first position, the supporting unit supports the main body. When the supporting unit rotates to a second position, the casing and the main body are separated.
