Sliding Latch Mechanism for Battery Cover Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices often have varying designs for battery cover detachment, leading to potential damage due to user unfamiliarity with the proper detachment method, resulting in inconvenience and damage to the battery cover.
Innovation Solution
A portable electronic device design featuring a latch that slides along a direction to fix and lift the battery cover using an elastic unit, allowing easy detachment by moving the latch to a second position, which is then returned to the first position by a spring, preventing damage to the catch hooks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery cover is designed with a fixed detachment method, then the structure is simple, but the user may damage the catch hook due to unfamiliarity with the proper detachment method
Solution Approach 1:
The latch mechanism automatically performs the lifting action when activated by the user. When the user slides the latch to the detached state, the elastic unit self-activates to lift the battery cover, eliminating the need for the user to manually pry or force the cover open, thereby preventing damage to the catch hook while maintaining structural simplicity
Solution Approach 2:
The latch serves as an intermediary component between the user and the battery cover. Instead of the user directly manipulating the battery cover, the user interacts with the latch, which then mediates the detachment process by triggering the elastic unit to lift the cover, protecting the catch hook from direct user force
2Device complexity
If the battery cover is lifted manually by the user, then no additional components are needed, but the catch hook may be damaged due to improper user force
Solution Approach 1:
The latch acts as an intermediary that transforms user input into a controlled lifting motion. When the user slides the latch, it triggers the elastic unit to lift the battery cover at the correct position and with the correct force, preventing the user from applying harmful force directly to the catch hook
Solution Approach 2:
The elastic unit provides self-service by automatically generating the lifting force needed to detach the battery cover. Once the latch is activated, the elastic unit self-activates to lift the cover, eliminating the need for the user to apply manual lifting force that could damage the catch hook

AI summary
A portable electronic device includes a battery for providing electricity to the portable electronic device; a housing for accommodating the battery; a battery cover for covering the battery; a latch affixed to the housing in a slidable manner along a first direction, wherein when the latch is at a first position, the latch is capable of fixing the battery cover and the housing together; and an elastic unit for lifting the battery cover when the latch is at a second position.
