Pivoting Battery Casing for Wearable Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable communication devices, such as smart watches, have irreplaceable batteries that quickly deplete, requiring inconvenient and time-consuming recharging, leaving users without access if immediate charging is not possible.
Innovation Solution
A wearable device design featuring a battery casing with a pivoting upper machine body, elastic members, and a button mechanism that allows for rapid exposure and replacement of the battery by rotating the battery casing relative to the upper machine body, enabling quick and convenient battery swapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is made irreplaceable to reduce device complexity, then manufacturing precision and reliability are improved, but user convenience and operational flexibility deteriorate when battery power is depleted
Solution Approach 1:
The device is divided into separable modules: an upper machine body and a battery casing that can be independently removed and replaced. This segmentation allows the battery to be easily swapped without replacing the entire device, resolving the contradiction between maintaining reliability and enabling convenient battery replacement.
Solution Approach 2:
The connection between the upper machine body and battery casing is made dynamic rather than fixed. A pivoting mechanism with elastic members allows the battery casing to be quickly detached and reattached, transforming a static permanent connection into a dynamic reversible one that maintains reliability while enabling convenient replacement.
2Reliability
If a secure connection mechanism is used to fix battery casing position, then reliability is improved, but ease of operation for battery replacement deteriorates
Solution Approach 1:
The connection mechanism uses elastic members that provide both secure engagement during normal use and easy release during replacement. The pivoting connection allows the battery casing to be firmly held in position while enabling quick removal when needed, resolving the contradiction between connection reliability and replacement ease.
Solution Approach 2:
The elastic members automatically engage and disengage the connection without requiring additional tools or complex operations. The mechanism serves itself by using the natural elasticity to maintain connection during use and allow easy release during replacement, balancing reliability and ease of operation.
3Device complexity
If the battery casing is permanently fixed to the upper machine body, then device complexity is reduced, but productivity for battery replacement deteriorates
Solution Approach 1:
By segmenting the device into separable upper machine body and battery casing components, the patent enables rapid battery replacement without requiring complex disassembly procedures. This segmentation maintains relatively simple device structure while dramatically improving battery replacement productivity.
Solution Approach 2:
The dynamic pivoting connection allows the battery casing to be quickly detached and reattached through simple rotational motion. This dynamic connection mechanism maintains low device complexity while enabling high-speed battery replacement, resolving the contradiction between structure simplicity and replacement efficiency.
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
Facilitates rapid and convenient battery replacement in wearable devices, allowing users to easily swap batteries without needing to remove the device from the wrist, thus maintaining functionality and user convenience.
Implementation Method 1
The first elastic member includes two opposite ends, and an end of the two opposite ends of the first elastic member is fixed to the upper machine body. The button is fixed to the other end of the two opposite ends of the first elastic member and includes a hook, wherein the hook is movably fixed to or released from the engaged member of the battery casing.
Implementation Method 2
The upper machine body is pivoted to the battery casing, so as to shield or expose the battery accommodating space.

AI summary
A wearable device includes a battery casing, an upper machine body, a first elastic member and a button. The battery casing has a battery accommodating space and an engaged member. The upper machine body is pivotally connected to the battery casing to cover or expose the battery accommodating space. Two ends of the first elastic member are fixed to the upper machine body and the button, respectively. The button includes a hook movably fixed to or released from the engaged member. When the battery casing is at a first position, the upper machine body covers the battery casing to shield the battery accommodating space, and the hook is fixed to the engaged member. Pushing the button to press the first elastic member, the button is released from the engaged member, and the battery casing is rotated to a second position to expose the battery accommodating space.
