Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Worry stones lack quantifiable tracking of user engagement, frequency, and stress relief data, making it difficult to identify and predict stressful situations effectively.
Innovation Solution
An electronic worry stone device with an internal sensing and processing system that communicates data to a user computing device, allowing for real-time tracking of contact time, rubbing rate, and pressure, and storing this data on a server for historical analysis and user interface display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a traditional worry stone is used, then it provides relaxation and stress relief, but the engagement data and stress relief effectiveness cannot be tracked or quantified
Solution Approach 1:
The patent combines a traditional worry stone with electronic sensing components (accelerometer, pressure sensor, gyroscope) and communication modules into a single integrated device. This merging allows the device to maintain its relaxation function while simultaneously capturing engagement data through multiple sensors that track rubbing motion, pressure applied, and duration of use.
Solution Approach 2:
The worry stone device serves multiple functions: it provides tactile relaxation through traditional rubbing, simultaneously acts as a data collection device with multiple sensors, functions as a communication device that transmits data to mobile applications, and serves as a historical record-keeping system that tracks engagement patterns over time for stress analysis.
2Reliability
If no tracking system is implemented, then the device remains simple, but there is no historical database to predict or avoid stressful situations
Solution Approach 1:
The system continuously collects and stores engagement data in advance, building a historical database of rubbing patterns, pressure levels, and duration over time. This preliminary data accumulation enables future stress prediction and pattern recognition without requiring complex real-time processing during actual stress events.
Solution Approach 2:
The device implements feedback loops where sensor data from rubbing motion is continuously monitored, processed by microcontrollers, transmitted to mobile applications, and analyzed to provide insights about stress patterns. This feedback mechanism allows users to understand their stress responses and adjust behaviors accordingly.
3Measurement precision
If real-time data collection is implemented, then engagement metrics can be monitored, but energy consumption increases
Solution Approach 1:
The sensing system operates periodically rather than continuously, with sensors activated at specific intervals during rubbing motion. The accelerometer and pressure sensor capture data at key moments in the rubbing cycle, providing sufficient measurement precision while allowing the system to enter low-power states between measurement periods.
Solution Approach 2:
The system uses a multi-sensor array that captures more data than strictly necessary (excessive action), but processes only the most relevant metrics for stress analysis. This approach ensures comprehensive measurement coverage while managing power consumption by prioritizing critical data collection over complete environmental monitoring.

AI summary
A worry stone system is provided. The system includes a worry stone device having an internal sensing and processing system, a user computing device, and a server having a memory storing worry stone data. The server may be programmed to receive worry stone data from the worry stone device through the user computing device in near real-time that includes contact time between the user and the worry stone device, a rate of rubbing the worry stone device, and/or a pressure used for rubbing the worry stone device. The server may process the worry stone data and send the same for display on the user computing device. The server operates to continuously process received near real-time worry stone data and send the processed worry stone data for display on the user computing device during the entire time of engagement of the worry stone device by the user.
