Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a growing need for devices that assist individuals with reduced muscular strength or joint problems due to aging or injury in walking and exercising, while also providing personalized exercise guidance and feedback.
Innovation Solution
A wearable device that applies assistance or resistance forces to the user's body, equipped with sensors to measure movement and communicate with an electronic device to estimate exercise amount and provide graphical user interfaces for personalized exercise goals and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wearable device provides basic exercise assistance without intensity selection, then device complexity is reduced, but exercise effectiveness and personalization are insufficient
Solution Approach 1:
The system divides functionality between the wearable device (sensor data collection and basic processing) and the electronic device (intensity selection, exercise amount estimation, and GUI display). This segmentation allows the wearable device to remain relatively simple while the electronic device handles the complex personalization and analysis functions.
Solution Approach 2:
The electronic device acts as an intermediary between the wearable device and the user. It receives sensor data from the wearable device, processes the exercise amount estimation based on selected intensity levels, and presents the results through a graphical interface, thereby enabling personalization without complicating the wearable device itself.
2Loss of information
If the wearable device processes and displays exercise data locally, then real-time feedback is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent extracts the complex data processing and display functions from the wearable device and places them in the electronic device. The wearable device focuses on collecting and transmitting sensor data, while the electronic device performs the exercise amount estimation and generates the graphical user interface, thereby reducing the complexity burden on the wearable device.
Solution Approach 2:
The system uses sensor data from the wearable device as input to generate an estimated exercise amount output displayed on the electronic device. This data copying and processing approach allows accurate feedback to be provided without requiring the wearable device to contain all processing capabilities.
3Reliability
If exercise intensity is not selected, then ease of operation is improved, but exercise effectiveness and target achievement are reduced
Solution Approach 1:
The system requires the user to select an exercise intensity level before beginning the exercise routine. This preliminary action ensures that the exercise is tailored to the user's capabilities and goals, improving effectiveness. The electronic device then uses this selected intensity to calculate and display the target exercise amount and provide feedback throughout the exercise session.
Data Source
AI summary
An electronic device and/or a wearable device providing exercise amount measurement information, and/or operation methods thereof. An electronic device may include: a communication module configured to receive, from a wearable device, sensor data including movement information during an exercise of a user wearing the wearable device; an input module configured to receive a user input that selects an exercise intensity to be applied to the exercise of the user; a processor configured to estimate an exercise amount of the user based on the received sensor data and the selected exercise intensity, and generate an exercise activity indicator including at least one graphic indicator indicating the estimated exercise amount; and a display module configured to output a graphical user interface (GUI) on which the exercise activity indicator is displayed.
