Battery Locking Assembly with Dynamic Pressing Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices with separable batteries are prone to accidental battery detachment when subjected to impact or falls, leading to potential battery damage and data loss due to power interruption.
Innovation Solution
A locking assembly comprising a linking element, a limiting element, and a pressing element, which engages the battery securely by moving in non-parallel directions, ensuring the battery remains fixed even under external stress, and includes an elastic element for secure retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional battery fixing mechanism with a key and tenon is used, then the battery can be easily changed by the user, but the battery may inadvertently separate from the electronic device when subjected to impact or falls
Solution Approach 1:
The locking assembly employs a dynamic pressing element that can move between a pressing state (engaging the limiting portion) and a released state (disengaged from the limiting portion). This dynamic mechanism allows the battery to be securely locked during normal operation but easily removed when the pressing element is intentionally actuated, resolving the contradiction between secure retention and easy replacement.
Solution Approach 2:
The pressing element serves as an intermediary component between the user's manual operation and the battery retention system. By moving the pressing element, the user indirectly controls the engagement state of the locking assembly, enabling intentional battery removal without directly manipulating the engaging portions. This intermediary mechanism prevents accidental detachment while maintaining ease of replacement.
2Productivity
If the battery is easily separable from the housing, then the user can change the battery quickly, but the battery is likely to be damaged or cause data loss due to inadvertent separation during impact or falls
Solution Approach 1:
The locking assembly applies preliminary anti-action by maintaining a constant pressing force on the pressing element through the limiting portion. This pre-applied counteracting force prevents the engaging portions from disengaging under external impacts or vibrations, thereby protecting against battery damage and data loss while still allowing quick removal when the pressing element is intentionally actuated.
Solution Approach 2:
The locking assembly provides beforehand cushioning against accidental battery detachment by maintaining continuous engagement of the pressing element with the limiting portion. This pre-established protective mechanism cushions the battery connection against external shocks, vibrations, or impacts that may occur during device usage, preventing inadvertent separation and associated damage.
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 locking assembly allows easy battery replacement while preventing inadvertent detachment, ensuring the battery remains securely attached during impacts or falls, thus preventing power interruptions and data loss, enhancing the operational security of the electronic device.
Implementation Method 1
The pressing element is connected to the linking element and disposed at the first limiting portion to fix relative positions of the first engaging portion and the second engaging portion

AI summary
An electronic device includes a housing, a locking assembly and a battery demountably disposed on the housing and including a first engaging portion. The locking assembly includes a limiting element, a pressing element and a linking element movably disposed on the housing and includes a second engaging portion. The first and second engaging portions engage, allowing the battery to be fixedly disposed on the housing. The limiting element is disposed on the housing and includes first and second limiting portions. The pressing element is connected to the linking element and disposed at the first limiting portion to fix relative positions of the first and second engaging portions. When the pressing element separates from the first limiting portion and moves to the second limiting portion, the linking element drives the second engaging portion to separate from the first engaging portion, causing the battery to separate from the housing.
