Mobile Terminal Battery Cover Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial mobile terminal batteries, especially waterproof ones, are difficult to remove frequently for replacement without compromising durability in drop tests, as existing designs often fail to balance ease of removal with structural integrity.
Innovation Solution
A locking mechanism comprising a lock button, a slide latch, and a spring member, where the slide latch slides between positions, and the spring member's deformation allows the latch to snap or unsnap, enabling easy battery cover removal while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery is made easy to remove for frequent replacement, then the ease of operation is improved, but the device fails in drop tests due to reduced structural integrity
Solution Approach 1:
The locking mechanism transitions between locked and unlocked states dynamically. The slide latch moves between a first position (locked) and a second position (unlocked), allowing the battery cover to be securely fixed during normal use but easily removable when needed. This dynamic state change resolves the contradiction by providing both structural integrity during operation and ease of removal when required.
Solution Approach 2:
The spring member changes its deformation state based on the latch position. When the slide latch is in the first position, the spring is deformed to maintain the locked state, providing strong holding force for drop test resistance. When the latch moves to the second position, the spring returns to its original state, allowing easy removal. This parameter change in spring deformation resolves the contradiction between secure locking and easy unlocking.
2Ease of operation
If a locking mechanism is added to enable easy battery removal, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism integrates multiple functions into a compact structure. The slide latch combines the locking action, the spring member provides both the locking force and the release mechanism, and the protrusion part integrates the blocking and unblocking functions. This merging of functions into a single integrated mechanism achieves easy battery removal without significantly increasing overall device complexity.
Solution Approach 2:
The locking mechanism is divided into distinct functional segments: the slide latch for position control, the spring member for force application, and the protrusion part for blocking/unblocking. Each segment performs a specific function, allowing the complex locking mechanism to be designed and manufactured as modular components that assemble into a compact whole, thereby managing complexity effectively.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism allows for frequent battery replacement without compromising the device's ability to withstand drop tests, ensuring both ease of use and durability.
Implementation Method 1
the contact part applies the force to the spring reaction part to result in a spring deformation, the spring deformation causes the contact part to move, thereby bringing the protrusion part (354) moving to an unblocked position

AI summary
The present invention provides a locking mechanism in a mobile terminal and a method of manufacturing the same. The locking mechanism comprises a slider, latch, button, and spring. The slider and latch include openings and may translate between a locked position and an unlocked position. The latch may include a protrusion that limits the translation of the slider and the latch when in the locked position. The button is located within the opening of the slider and the opening of the latch, and the spring member is fixed adjacent the latch. In an instance in which an external force is applied to the button, the external force deforms the spring member such that contact between a vertical edge of the protrusion and the spring is precluded allowing translation of the slider and the latch between the locked position and the unlocked position.
