Battery Pack Lever Mechanism for Secure Detachment on Inclined Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with detachable battery packs face challenges in secure and easy detachment, especially when the device is in an inclined position, as existing mechanisms may not prevent the battery from sliding out or require complex operations.
Innovation Solution
A detaching/attaching mechanism using an operating lever that moves in two directions to create a gap for finger insertion, combined with protrusions and a holding mechanism involving a coil spring to securely lock and unlock the battery pack, ensuring easy detachment and secure attachment without external hooks on the device's surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple latch mechanism is used to attach the battery pack, then the device complexity is reduced, but the battery pack may slide out when the device is in an inclined position
Solution Approach 1:
The operating lever is moved in advance to a specific position that creates a gap between the battery pack and mounting part, allowing the user to insert a finger for detachment. This preliminary action prepares the system for easy user intervention without requiring complex sensors or actuators.
Solution Approach 2:
The protrusion on the operating lever acts as an intermediary element that directly engages with the battery pack. When the lever is moved, the protrusion creates the gap and provides a mechanical interface for the user's finger, simplifying the detachment process while ensuring reliable retention during normal operation.
2Reliability
If no gap is formed between the battery pack and mounting part, then the attachment is more secure, but the user cannot easily detach the battery pack
Solution Approach 1:
The operating lever is designed to be movable between a first position (where the battery pack is securely attached) and a second position (where a gap is created for detachment). This dynamic transition allows the system to switch between secure attachment and easy detachment states based on user needs.
Solution Approach 2:
Before the user attempts to detach the battery pack, the operating lever is moved to create a gap between the battery pack and mounting part. This preliminary action prepares the system by providing finger access space, making the detachment operation easy and intuitive without requiring force or complex maneuvers.
3Reliability
If external hooks are added to the device surface to prevent battery sliding, then the battery retention is improved, but the device外观 (appearance) is compromised and complexity increases
Solution Approach 1:
The operating lever is integrated with the housing structure, combining the functions of a release mechanism and a retention structure. The lever's protrusion works in conjunction with the mounting part's geometry to provide both secure attachment and controlled detachment, eliminating the need for separate external hooks or retention features.
Solution Approach 2:
The operating lever serves multiple functions: it acts as a release mechanism to create a gap for detachment, and simultaneously serves as a retention structure that prevents the battery pack from sliding out during normal operation. This multi-functionality eliminates the need for additional external hooks or retention features.
