Integrated Squat Carriage Locking for Compact Weight Racks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing squat machines and weight racks are bulky and difficult to operate, lacking compact structures with improved safety and integration capabilities.
Innovation Solution
A weightlifting machine with a user-engaging device, carriage support, and a cable system that allows for vertical movement of a carriage, featuring a locking mechanism to stabilize the carriage at elevated positions, and a platform for user support, integrated with a weight rack for compact operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If existing squat machines use multiple support posts and cables to suspend a moveable weight, then the machine provides stable weightlifting functionality, but the machine occupies a large footprint and becomes bulky
Solution Approach 1:
The patent integrates the squat machine directly into the weight rack structure by merging the carriage support system with the rack's vertical posts. The carriage moves along the vertical posts of the weight rack itself, eliminating the need for separate support posts and reducing the overall footprint while maintaining structural stability for weightlifting operations
Solution Approach 2:
The weight rack is designed to serve multiple functions: it provides both weight storage capabilities and structural support for the squat machine's carriage system. The vertical posts of the rack double as guide rails for the carriage, allowing the same structure to fulfill both support and storage roles, thereby reducing the need for additional dedicated support elements
2Ease of operation
If existing belt squat machines use a belt or harness connected by cables and pulleys to a weight, then the machine provides squat lifting functionality, but the machine becomes difficult or awkward for users to operate
Solution Approach 1:
The patent removes the complex cable and pulley system from the squat machine design. Instead of using cables and pulleys to connect the user harness to the weight, the carriage moves directly along the vertical posts with the weight attached to the carriage itself, simplifying the operational mechanism and making it more intuitive for users
Solution Approach 2:
Rather than suspending the weight from above via cables as in traditional belt squat machines, the patent inverts the approach by having the carriage move vertically along the rack posts with the weight attached to the carriage structure itself, reversing the traditional suspension mechanism and simplifying user interaction
3Reliability
If existing squat machines lack integration with weight racks, then the machines can be standalone, but they do not provide compact structures with improved safety
Solution Approach 1:
The squat machine is merged with the weight rack into a single integrated structure where the carriage moves along the rack's vertical posts. This integration provides inherent safety through the robust rack structure while maintaining versatility as the system can accommodate different weight configurations and user requirements
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 machine provides a compact, safe, and easily operable squat lifting solution that can be integrated into existing weight racks, enhancing user experience and safety.
Implementation Method 1
one or more pulleys connected to the weightlifting machine to guide a path of the cable
Implementation Method 2
a locking mechanism including a locking member that is moveable between a locking position, where the locking member engages the carriage and supports the carriage at an elevated position
Data Source
AI summary
A weightlifting machine includes a carriage support, a carriage moveably mounted on the carriage support and configured to move along the carriage support, and a locking mechanism that is moveable between a locking position, where the locking mechanism engages the carriage and supports the carriage at an elevated position above a lowermost position of the carriage, and a release position, where the locking mechanism does not engage the carriage, and the carriage is free to move below the elevated position.
