Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices, such as smartwatches, face challenges with high power consumption and limited functionality due to the need for strong CPUs to handle tasks like Bluetooth protocols and display operations, resulting in short standby times and a user experience similar to mobile phones rather than traditional watches.
Innovation Solution
An electronic apparatus with a dual processing system, featuring a first processing unit for complex operations and a second processing unit for low-power tasks, along with a sharing unit that selectively operates based on predetermined conditions, and a fixing unit for user positioning, allowing the device to switch components according to usage environments to conserve power while enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a strong CPU is used to handle Bluetooth protocols and display operations, then functionality is improved, but power consumption increases
Solution Approach 1:
The processing system is divided into two distinct parts: a first processing unit (low-power microcontroller) and a second processing unit (high-performance processor). Each unit handles specific tasks independently, allowing the system to achieve high functionality when needed while consuming minimal power during basic operations. The first processing unit manages essential watch functions, while the second processing unit handles complex tasks like Bluetooth protocols and graphical display operations only when required.
2Adaptability or versatility
If a strong CPU is used to handle Bluetooth protocols and display operations, then functionality is improved, but standby time decreases
Solution Approach 1:
The processing system is divided into two distinct parts: a first processing unit (low-power microcontroller) and a second processing unit (high-performance processor). Each unit handles specific tasks independently, allowing the system to achieve high functionality when needed while consuming minimal power during basic operations. The first processing unit manages essential watch functions, while the second processing unit handles complex tasks like Bluetooth protocols and graphical display operations only when required.
Solution Approach 2:
The system employs periodic operation where the second processing unit (high-performance processor) is activated only when needed for specific tasks such as Bluetooth communication or display updates, while the first processing unit continuously manages basic timekeeping functions. This periodic activation pattern significantly extends standby time by keeping the high-power component dormant during extended periods.

4Productivity
If a strong CPU is used, then processing capability is improved, but device complexity increases
Solution Approach 1:
The processing system is divided into two distinct parts: a first processing unit (low-power microcontroller) and a second processing unit (high-performance processor). Each unit handles specific tasks independently, allowing the system to achieve high functionality when needed while consuming minimal power during basic operations. The first processing unit manages essential watch functions, while the second processing unit handles complex tasks like Bluetooth protocols and graphical display operations only when required.
Solution Approach 2:
The first processing unit serves as a universal low-power controller that can manage multiple basic functions including timekeeping, simple display updates, and sensor data acquisition. The second processing unit provides universal high-performance processing for complex tasks. This multi-functionality approach reduces overall system complexity by creating two versatile processing units rather than requiring specialized hardware for each function.
