Exercise Machine Control Unit Automatic Unlocking via Presence Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exercise machines with control units often enter a standby mode after inactivity, requiring manual unlocking, which can be confusing for users, especially those unfamiliar with technology or in a state of fatigue, as the control unit may display a screensaver or dark screen without clear instructions for unlocking.
Innovation Solution
Incorporating a presence detection sensor that generates an electrical signal when a user occupies the machine, allowing the control unit to automatically switch from a locking condition to an operating condition, enabling users to issue commands by interpreting the signal as an interrupt to terminate the locking state and enable command issuance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the control unit enters standby mode after inactivity, then energy consumption is reduced, but user operation becomes less intuitive and more confusing
Solution Approach 1:
The control unit automatically detects user presence through sensors and autonomously transitions from locked standby mode to unlocked operating mode without requiring manual user intervention. The system serves itself by monitoring its environment and making state transitions based on detected conditions, eliminating the need for users to figure out unlocking procedures.
2Use of energy by moving object
If the control unit displays a screensaver or dark screen in standby mode, then visual information is reduced to save energy, but user guidance for unlocking is lost
Solution Approach 1:
The control unit uses sensors to continuously monitor the environment and detect user presence. This feedback mechanism allows the system to determine when a user is approaching or making contact with the device, triggering automatic state transitions from locked to unlocked mode without requiring visual instructions on the display.
3Reliability
If manual unlocking is required, then system security is maintained, but user fatigue and confusion increase during training sessions
Solution Approach 1:
The patent replaces manual mechanical interaction (buttons, switches) with automatic sensor-based detection. The system uses sensors to detect user presence and automatically transitions the control unit state, eliminating the need for users to physically interact with unlocking mechanisms while maintaining system security through controlled state transitions.

AI summary
A method for unlocking a control unit of an exercise machine includes providing the exercise machine, having at least one sensor for detecting presence of a user on the exercise machine, with at least one electrical signal representative of a detection carried out at the time of the occupation of the exercise machine by a user. The method further includes switching, by the exercise machine, the control unit of the exercise machine from a first locking condition to at least a second operating condition in which the user may issue commands to the exercise machine by the control unit, based on the at least one electrical signal provided by said at least one sensor for detecting the presence of the user on the exercise machine.
