Squat Exercise Apparatus Dynamic Weight Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in safely and effectively performing squat exercises due to challenges in controlling and managing the weight during the lowering and rising motions, which can lead to safety concerns and inefficient workouts.
Innovation Solution
The squat exercise apparatus incorporates an actuator assembly with a trigger and cable system that allows users to selectively couple and decouple weight members from lift arms, providing improved control over weight application and limiting inadvertent weight release, especially during the lowering phase, thus enhancing user safety and customization of the squat motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional free weights or fixed weight machines are used, then weight loading is simple, but user control over weight application timing and safety is insufficient
Solution Approach 1:
The patent implements a dynamic weight selection system where the carrier rod can be positioned at different locations along its length to engage with different sets of weight members. This allows the user to dynamically adjust the weight configuration during the exercise motion, providing both safety control and operational flexibility. The dynamic positioning resolves the contradiction by enabling real-time weight management rather than fixed pre-selection.
Solution Approach 2:
The patent introduces an intermediary mechanism (the carrier rod with selective engagement points) between the user and the weight members. This intermediary allows the user to control weight application indirectly through positional selection, enhancing safety while maintaining ease of operation. The carrier rod acts as a mediator that translates user intent into controlled weight engagement.
2Adaptability or versatility
If weight members are fixed to lift arms, then weight application is reliable, but user ability to adjust and control weight during exercise is limited
Solution Approach 1:
The patent segments the weight system into multiple independent weight members that can be selectively engaged or disengaged from the lift arms. The carrier rod provides multiple engagement points along its length, allowing the user to select different combinations of weight members. This segmentation enables flexible weight adaptation while maintaining reliable weight application through positive engagement at selected positions.
Solution Approach 2:
The system transitions from fixed weight attachment to dynamic weight selection. The carrier rod can be positioned at different locations to engage different weight configurations, allowing the user to adapt the weight loading during the exercise. This dynamic capability resolves the contradiction by providing both versatility in weight selection and reliability through secure engagement at each position.
3Ease of operation
If complex actuator systems are added for weight control, then user safety and control improve, but device complexity increases
Solution Approach 1:
The patent implements a self-service weight control mechanism where the user directly manipulates the carrier rod position to select weights, without requiring complex external actuators or electronic systems. The mechanical design allows the user's own actions to control the weight engagement, simplifying the overall system while maintaining ease of operation and safety.
Solution Approach 2:
The carrier rod serves as a simple mechanical intermediary that translates user input into weight selection without requiring complex actuation systems. This straightforward mechanical mediation achieves effective weight control with minimal added complexity, resolving the contradiction between ease of operation and device complexity.

AI summary
A squat exercise apparatus includes a support structure, a plurality of weight members, at least one lift arm, and an actuator. The plurality of weight members is positioned in the support structure. The at least one lift arm has a first end coupled to the support structure and a second end arranged for contact by a user to move the at least one arm vertically during a squat exercise. The actuator assembly is operable by the user to selectively couple the at least one lift arm to at least one of the weight members during the squat exercise. A portion of the actuator assembly is carried by the at least one lift arm.
