Detachable Smartwatch Power Control via Segmented Body Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart watches and smart bands face challenges in maintaining functionality, especially when power is low, as they require continuous wear to display information like time, date, and user status, and existing solutions do not efficiently manage power supply during charging or separate usage scenarios.
Innovation Solution
The electronic device consists of a first body with a frame and fixing apparatus, and a second body with a main functional unit, allowing for detachable connection. A power supply control method detects when the second body is detached or coupled, switching between powering the auxiliary functional unit in the first body and both units when connected, ensuring continuous operation and charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the smart watch or smart band is kept fixed to the user's wrist to maintain continuous operation and display information, then the device can continuously display time, date, and user status, but the device cannot be detached for charging or separate usage scenarios
Solution Approach 1:
The device is divided into two detachable bodies: a first body (frame with fixing apparatus) and a second body (main functional unit). This segmentation allows the device to be worn continuously on the wrist while enabling the second body to be detached for charging or separate usage, resolving the contradiction between continuous operation and charging capability
Solution Approach 2:
The first body is designed with an auxiliary functional unit that can independently perform monitoring functions when the second body is detached. This multi-functionality ensures the device can continue to operate and display information even when the main functional unit is removed for charging, maintaining both continuous operation capability and charging versatility
2Productivity
If the device requires continuous wear to display information and maintain functionality, then the device can provide real-time information display, but the device must remain fixed even when power is low or charging is needed
Solution Approach 1:
By separating the device into a first body with fixing apparatus and a second body with main functional unit, the design enables the second body to be easily detached for charging while the first body remains on the wrist to continue displaying information, thus maintaining productivity while improving ease of operation for charging
Solution Approach 2:
The first body's auxiliary functional unit can independently monitor and display basic information when the second body is detached for charging. This self-service capability ensures continuous information display functionality while allowing convenient charging without requiring the entire device to remain worn

AI summary
An electronic device includes a first body and a second body which are detachably connected. The first body includes a frame and a fixing apparatus, and the second body includes a main functional unit. The fixing apparatus is connected to the frame and configured to fix the electronic device to an operation body. When the electronic device is fixed to the operation body via the fixing apparatus, the fixing apparatus and the frame form a ring-shaped space. A method for controlling power supply of the electronic device is also provided.
