Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic timepieces face challenges in efficiently redesigning the control substrate without affecting the overall functionality and compatibility with various models.
Innovation Solution
The electronic timepiece incorporates a dual-substrate design, where a first substrate with a processor and selector switches connections between connection terminals, and a second substrate with peripheral devices, allowing dynamic switching of connections based on processor control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional single substrate design is used, then the control substrate can directly control peripheral devices, but any change in device configuration requires redesigning the control substrate
Solution Approach 1:
The system is divided into two separate substrates: a first substrate containing the processor and selector, and a second substrate containing the peripheral devices. This segmentation allows the first substrate to remain unchanged while the second substrate can be reconfigured to accommodate different device configurations, thereby improving adaptability without increasing overall system complexity.
Solution Approach 2:
The selector on the first substrate dynamically switches the connection between the processor and different peripheral devices based on operational requirements. This dynamic connection switching enables the system to adapt to different configurations without requiring physical redesign of the substrate layout.
2Adaptability or versatility
If multiple peripheral devices are connected to a single processor, then the system can support multiple functions, but the connection management becomes complex
Solution Approach 1:
The selector acts as an intermediary component between the processor and multiple peripheral devices. It manages the connections by selectively routing signals from the processor to the appropriate device, thereby simplifying connection management while supporting multiple devices and functions.
3Reliability
If the control substrate is redesigned for each model, then each model can have optimized connections, but the development cost and time increase
Solution Approach 1:
The first substrate with the processor and selector is designed as a universal platform that can support multiple different models and configurations. By keeping this substrate unchanged and only modifying the second substrate with peripheral devices, the system achieves model-specific optimization without requiring complete redesign, thereby reducing development time and costs.

AI summary
An electronic timepiece includes, a first substrate that includes a plurality of first connection terminals, a processor, and a selector that switches a connection between the first connection terminals and the processor, and a second substrate that includes a plurality of second connection terminals that are connected to a plurality of peripheral devices that each perform a certain operation. Each of the second connection terminals is connected to each of the first connection terminals. The selector switches the first connection terminal that is connected to the processor based on control by the processor.
