Dual-Program Activation Control for Battery-Powered Medical Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery-powered medical apparatuses, such as endoscopic devices, face challenges during software updates, where faults can occur, leading to incomplete activation and potential battery drainage without ensuring a backup activation mechanism.
Innovation Solution
Incorporating a dual-program memory system where a first program is executed initially, and if activation fails within a predetermined time, the system switches to a second program, and if that also fails, it stops the power supply to prevent battery consumption, ensuring a fail-safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single program is used for activation, then the device structure is simple, but the reliability of activation is reduced due to potential faults during updates
Solution Approach 1:
The memory system is segmented into a first memory storing a first program and a second memory storing a second program. The processor selectively executes different programs based on activation conditions, thereby improving activation reliability without requiring a completely redundant system.
Solution Approach 2:
The second program is prepared in advance as a backup activation program. When the first program fails to complete activation within the predetermined time period, the processor automatically switches to execute the second program, ensuring continuous operational capability.
2Reliability
If the processor waits for activation completion without time limit, then activation accuracy is ensured, but battery energy is consumed during prolonged operation
Solution Approach 1:
The activation process uses periodic time checks to determine whether activation is complete. The processor monitors the activation progress at regular intervals and compares the current time against the start time to determine if the predetermined time period has elapsed, balancing reliability with energy efficiency.
3Reliability
If the system switches to second program immediately on first program failure, then activation reliability is improved, but the risk of battery drainage increases if second program also fails
Solution Approach 1:
The system implements a time-limited backup mechanism where the processor only switches to the second program if the first program fails within a predetermined time period. This预先设定的时间限制 acts as a cushion to prevent unlimited energy consumption while still providing backup activation capability.
Solution Approach 2:
The processor continuously monitors the activation progress and provides feedback on whether the activation is complete. Based on this feedback and the elapsed time, the processor makes informed decisions about switching programs or stopping execution, thereby preventing unnecessary energy drainage.

AI summary
A battery-powered medical apparatus including a first memory configured to store a first program, a second memory configured to store a second program, which is different than the first program, and a processor. The processor executes activation of the battery-powered medical apparatus by executing the first program stored in the first memory in response to receiving an activation instruction. In response to the activation failing to complete within a first predetermined period of time, the processor switches from the first program to the second program, and executes the activation of the battery-powered medical apparatus by executing the second program stored in the second memory. The processor then stops power supply from a battery in response to the activation executed by the second program failing to complete within a second predetermined period of time.
