Multi-Function Safety Key for Exercise Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety keys for exercise devices are limited in function and usefulness, primarily serving to disable the device when not properly connected, lacking advanced safety and user identification features.
Innovation Solution
A key with a safety mechanism that connects to a safety port on an exercise device, enabling operational or non-operational configurations, and a user identification mechanism that communicates user data, including key identifying information, via wireless or physical connections, allowing personalized settings and data storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional safety key is used to disable the exercise device when not properly connected, then the device safety is improved, but the key functionality is limited and lacks user identification features
Solution Approach 1:
The key is designed to perform multiple functions: it serves as a safety mechanism that disables the device when not properly connected, and simultaneously as a user identification device that communicates user data to the exercise device through a communicatively connectable interface. This multi-functionality resolves the contradiction by expanding key capabilities beyond simple safety switching.
2Adaptability or versatility
If the key includes both safety mechanism and user identification mechanism, then the key versatility is improved, but the device complexity increases
Solution Approach 1:
The patent combines the safety mechanism and user identification mechanism into a single integrated key device. The safety mechanism includes a safety port that connects to the exercise device, while the user identification mechanism includes a communicatively connectable interface (such as RFID chip, Bluetooth module, or USB connector) that transmits user data through the same or adjacent connection interface. This merging reduces overall system complexity compared to having separate safety key and identification devices.
3Ease of operation
If the user identification mechanism transmits data wirelessly or through physical connection, then the user identification capability is improved, but the need for repeated identification input is eliminated
Solution Approach 1:
The user identification mechanism stores user data (such as name, age, weight, fitness goals) in advance within the key device or associated memory. When the key is connected to the exercise device, this pre-stored information is automatically transmitted without requiring the user to re-enter data during each workout session. This preliminary data storage and automatic transmission eliminates repeated identification input while maintaining data integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances safety by ensuring the device is only operational with a connected key and provides personalized user settings and data management, eliminating the need for repeated identification and enhancing user experience.
Implementation Method 1
a safety mechanism that is operatively connectable to a safety port on an exercise device
Implementation Method 2
The user identification mechanism transmits user identification information to the exercise device when the user identification mechanism is communicatively connected to the user identification port
Implementation Method 3
a magnet is used to maintain an operative connection between the key and an exercise device
Data Source
AI summary
A key includes a safety mechanism operatively connectable to a safety port on an exercise device. When the safety mechanism is operatively connected to the safety port, the exercise device is placed in an operational configuration and when disconnected, the exercise device is in a non-operational configuration. The key further includes a user identification mechanism that is communicatively connectable to a user identification port on the exercise device and transmits user identification information to the exercise device.
