Toilet Controller Automatic Bio Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toilet devices face challenges in automatically transmitting biological information to personal digital assistants without user intervention, particularly when the device is not responding due to task-kill events, requiring users to manually re-establish communication or move out of range, which is inconvenient and time-consuming.
Innovation Solution
A toilet device with a controller that switches the personal digital assistant from an inactive to an active state by transmitting an activation signal, allowing for automatic transmission of biological information by controlling a transmission period and a suspension period, ensuring continuous communication and reducing user effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the toilet device regularly transmits the activation signal to the personal digital assistant, then the application software can be activated in the background without user operation, but the personal digital assistant may no longer respond to subsequent activation signals after task-kill
Solution Approach 1:
The controller suspends transmission of the activation signal during a predetermined period after detecting user approach, before actually transmitting biological information. This preliminary suspension action prevents the personal digital assistant from being in a non-responsive state when the activation signal is sent, thereby resolving the reliability issue while maintaining automatic activation functionality
2Ease of operation
If the user manually ends the application software (task-kill), then the personal digital assistant enters a non-responsive state, but the user must take additional action (move out of range or manually establish communication) to recover
Solution Approach 1:
The controller implements a transmission suspension period that begins before the personal digital assistant becomes unresponsive. By suspending the activation signal transmission during this predetermined period after detecting user approach, the system proactively avoids sending signals that would be rejected, thereby preventing the need for user recovery actions and eliminating time loss
3Productivity
If the toilet device transmits biological information at a fixed time, then the transmission schedule is simple, but the measurement result cannot be acquired close to the timing of defecation
Solution Approach 1:
The controller dynamically adjusts the transmission timing based on the detection of user approach. Instead of a fixed transmission schedule, the system suspends activation signal transmission during a predetermined period after detecting user approach, then transmits biological information at an appropriate time. This dynamic adjustment enables timely transmission close to defecation timing while maintaining manageable control complexity
