Weightlifting Locking Mechanism with Triggered Flexible Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Weightlifting injuries, particularly spinal and hip injuries, are common due to the lack of safety features in existing weightlifting equipment, which can lead to accidents when lifting heavy weights.
Innovation Solution
A weightlifting safety system with a locking mechanism that uses a flexible member and a trigger device to automatically lock the weight in place when released by the user, allowing safe stepping away and easy unlocking for resumption of lifting, incorporating various trigger technologies such as pushbuttons, ultrasonic sensors, lasers, and proximity sensors for secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional weightlifting equipment without safety features is used, then the device complexity is reduced, but the reliability and safety are worsened due to risk of spinal and hip injuries
Solution Approach 1:
The locking mechanism is pre-configured with a spring-loaded locking bar and trigger device that automatically engages to secure the weight in place before the user releases it, preventing accidental drops and ensuring safety without requiring complex manual intervention
Solution Approach 2:
The safety system automatically locks and unlocks based on user actions (releasing or gripping the bar), with the spring mechanism self-actuating to engage the locking bar into the receiver, eliminating the need for additional safety personnel or complex control systems
2Reliability
If the locking mechanism automatically locks when the user releases the bar, then the safety is improved by allowing users to step away, but the ease of operation is worsened due to the need to perform specific lifting motions to unlock
Solution Approach 1:
The trigger device provides immediate feedback by detecting when the user grips the bar, automatically sending a signal to unlock the locking mechanism, and the spring mechanism provides tactile feedback during the unlocking process, making the interaction intuitive and easy to operate
Solution Approach 2:
The patent replaces complex manual unlocking mechanisms with an automated system using trigger devices (optical, mechanical, or magnetic sensors) that detect user grip and automatically actuate the locking bar release, reducing the physical effort and complexity required to operate the safety feature
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
The system effectively reduces the risk of injuries by maintaining the weight's position when locked, allowing users to safely step away and resume lifting without manual handling, adaptable to various weightlifting configurations and surfaces.
Implementation Method 1
a storage that places tension on a flexible member, the flexible member being connected to the storage and to a weight of the weightlifting system
Implementation Method 2
a flexible member extends through the locking mechanism such that when the locking mechanism is locked, a length of the flexible member extending from the locking mechanism is fixed
Implementation Method 3
a pulley positioned on the mount between the storage component and the locking mechanism, wherein the flexible member extends from the storage component, around the pulley, and through the locking mechanism
Implementation Method 4
a pulley positioned on the mount between the storage component and the locking mechanism
