Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable communication device cooperation systems lack versatility in the use of watches as communication devices, limiting their functionality beyond basic timekeeping.
Innovation Solution
A portable communication device cooperation system comprising a master device and a slave device, where the master device communicates with an external device and transfers application programs to the slave device, enabling cooperative operation and various functionalities such as time display, service blocks, trigger blocks, and action blocks, allowing the slave device to operate independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the slave device stores and executes multiple slave application programs in separate slots, then the versatility and functionality of the slave device is improved, but the device complexity increases
Solution Approach 1:
The slave device divides its storage into multiple slots, with each slot capable of storing a separate slave application program. This segmentation allows the device to load and execute different functions in different slots, enabling versatility without requiring all functions to be permanently embedded in the device structure.
Solution Approach 2:
Each slot in the slave device is designed to be universal, capable of storing different types of slave application programs depending on what is transferred from the master device. This multi-functionality allows the same hardware structure to support various functionalities through software configuration rather than hardware modification.
2Adaptability or versatility
If the master device transfers application programs to the slave device, then the adaptability of the slave device is improved, but the loss of information increases due to program transfer requirements
Solution Approach 1:
The master device creates copies of application programs and transfers them to the slave device. Instead of the slave device needing to access or retrieve information from the master device continuously, complete copies are made and stored in the slave device's slots, eliminating information loss during operation.
Solution Approach 2:
The system performs preliminary action by transferring and storing application programs in the slave device before they are needed for execution. This advance preparation ensures that all necessary information is already present in the slave device, preventing any information loss during actual operation.
3Productivity
If the slave device executes slave application programs independently, then the productivity is improved, but the reliability may worsen due to potential execution errors
Solution Approach 1:
The application programs are segmented into master application programs (on the master device) and slave application programs (on the slave device). Each program type handles specific functions appropriate to its location, with the master program managing overall control and the slave program handling local execution tasks, thereby maintaining reliability through clear functional separation.
Solution Approach 2:
The system implements feedback mechanisms where the master device can monitor and control the slave device's operations. The master device can receive status information from the slave device and intervene if execution errors occur, ensuring that independent operation does not compromise overall system reliability.

AI summary
A portable communication device cooperation system includes a slave portable communication device that can communicate with a master portable communication device. Each of a plurality of slave-side slots of a slave-side storage unit included in the slave portable communication device stores a slave application program transferred from a master-side slot disposed in the master portable communication device. The slave application program includes part of information of a master application program, and causes the slave portable communication device to operate by being executed by a slave-side control unit of the slave portable communication device. As a result, the portable communication device cooperation system, the master portable communication device, and the slave portable communication device exhibit an effect of enabling the slave portable communication device to be variously used.
