Wearable Smartwatch Charging Cradle with Detachable Wireless Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartwatches face frequent battery depletion due to limited embedded battery capacity, requiring frequent charging, and existing charging solutions are complex and prone to unintended separation during use.
Innovation Solution
A wearable charging device with a cradle and wireless charging module that allows easy attachment and detachment, using a coil mount unit and power supply unit for electromagnetic charging, along with a moisture-absorbing mesh and cooling pad for user comfort, and a rotatable window cover for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable battery is mounted in a band for charging, then the smartwatch can be charged while worn, but the structure becomes complicated and difficult to manufacture
Solution Approach 1:
The device is divided into separate functional modules: a cradle unit with accommodation groove for the smartwatch, and a separate wireless charging module that can be attached or detached. This segmentation allows the charging function to be added without complicating the smartwatch structure itself.
Solution Approach 2:
An attachment-detachment unit acts as an intermediary mechanism between the cradle and wireless charging module, enabling easy connection and disconnection without complex internal modifications to the smartwatch structure.
2Ease of operation
If a charging module is mounted in the smartwatch main body, then charging can be performed, but the module may separate unintentionally during activity
Solution Approach 1:
The wireless charging module is designed to be dynamically attachable and detachable through the attachment-detachment unit, allowing secure connection during use and easy removal when needed, rather than being permanently fixed or requiring complex locking mechanisms.
3Ease of operation
If the smartwatch is worn on the wrist for mobile communication, then portability is achieved, but the embedded battery capacity is limited and requires frequent charging
Solution Approach 1:
The wireless charging module can be attached to the cradle in advance to charge the smartwatch battery before use, ensuring the battery is ready for extended activity without needing to remove the watch for charging.
Solution Approach 2:
The design enables continuous charging capability by allowing the wireless charging module to be attached and left in place, providing ongoing power supply to the smartwatch throughout the day without interruption to wear or activity.
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
Enables efficient wireless charging of smartwatch batteries while worn, preventing separation issues and enhancing user comfort with sweat management and heat dissipation.
Implementation Method 1
a wireless charging module mounted in the cradle to be attached to or detached from the cradle by an attachment-detachment unit and configured to generate an electromagnetic field to charge a battery embedded in the main body of the smartwatch
