Offline Transactions Using Secondary Device When Primary Battery Low
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic transaction systems using mobile devices are hindered by Internet connectivity issues and battery power limitations, preventing offline transactions when connectivity is unreliable or battery power is low.
Innovation Solution
A system and method enabling offline transactions using either a primary electronic device or a secondary electronic device, such as a wearable device, by loading funds onto the secondary device when the primary device's battery is low or when unreliable Internet connectivity is anticipated, allowing transactions to be conducted even without internet access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile electronic devices are used to conduct electronic transactions online, then transaction convenience is improved, but transaction reliability deteriorates when Internet connectivity is unreliable or battery power is low
Solution Approach 1:
The system divides the transaction capability into two independent parts: online transaction mode (requiring Internet connectivity) and offline transaction mode (using stored funds). The portable electronic device can segment its operation between these two modes, allowing transactions to continue in offline mode when online connectivity is unavailable, thus maintaining transaction reliability while preserving convenience.
Solution Approach 2:
The system performs preliminary actions by storing transaction funds and account information in the portable electronic device before Internet connectivity is lost or battery power becomes low. This advance preparation ensures that the device can immediately switch to offline transaction mode without interruption, resolving the contradiction between convenience and reliability.
2Speed
If funds are stored on a primary mobile device, then transaction speed is improved, but transaction availability deteriorates when the device battery is depleted
Solution Approach 1:
The portable electronic device acts as an intermediary between the user's financial account and the transaction system. It stores funds and account information locally, serving as a mediator that enables transactions to proceed without requiring real-time connection to the primary mobile device or online banking systems. This intermediary role ensures transaction availability even when the primary device battery is depleted.
Solution Approach 2:
The system creates a copy of the account information and funds balance from the primary mobile device or banking system and stores it in the portable electronic device. This copy enables offline transactions to proceed at full speed without requiring access to the primary device, resolving the contradiction between transaction speed and availability.
3Reliability
If offline transaction capability is added to portable devices, then transaction availability is improved, but device complexity increases
Solution Approach 1:
The portable electronic device is designed with multi-functionality, serving both as a regular communication device (when online) and as an offline transaction terminal (when offline). By integrating both online and offline transaction capabilities into a single device, the system avoids the need for separate dedicated offline devices, thereby limiting the increase in complexity while maximizing transaction availability.
Data Source
AI summary
A battery level of a primary electronic device is monitored by one or more hardware processors of the primary electronic device. A determination is made by the one or more hardware processors that the monitored battery level of the primary electronic device has dropped below a threshold. In response to the determination, a first amount of funds is electronically loaded to a secondary electronic device for offline purchases. The secondary electronic device is communicatively coupled to the primary electronic device. An offline electronic transaction is processed using the secondary electronic device based on the first amount of funds.
