Plate-Loaded Press Clamp-Sleeve Range-of-Motion Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weight training machines do not allow users to customize the range of motion, leading to unnatural and potentially injurious arcing movements, especially when reaching beyond the normal range of motion to access handles.
Innovation Solution
A system comprising a press partner clamp apparatus and sleeve device that can be removably attached to weight machines to modify the range of motion, including a C-shaped clamp for the arm side contact rod and a sleeve for the bumper, allowing users to customize the path of motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the exercise arm is pivotally mounted on the main frame with a fixed range of motion, then the machine structure is simple and stable, but the user cannot customize the range of motion leading to unnatural arcing movements and potential injury
Solution Approach 1:
The patent applies the dynamics principle by making the range of motion adjustable rather than fixed. The exercise arm can be positioned at different angles and the range of motion can be modified during use, allowing users to customize their exercise path while maintaining a relatively simple overall machine structure.
Solution Approach 2:
The patent segments the range of motion adjustment into separate adjustable components. The exercise arm is divided into segments that can be independently positioned and adjusted, allowing users to customize the range of motion without requiring a completely complex redesign of the entire machine.
2Ease of operation
If the handle is positioned far from the user to provide adequate space for movement, then the exercise can be performed with proper clearance, but the user must reach beyond the normal range of motion causing awkward hand or wrist positions and potential injury
Solution Approach 1:
The patent uses dynamics by allowing the exercise arm to be positioned at adjustable angles. Users can set the arm at an angle that brings the handle within their natural reach range, eliminating the need to reach beyond the normal range of motion while still providing adequate space for the exercise movement.
Solution Approach 2:
The patent applies local quality by adjusting the specific position and angle of the exercise arm to match the user's anatomy and movement capabilities. This localized adjustment ensures the handle is positioned optimally for each user without requiring changes to the entire machine structure.
3Adaptability or versatility
If the exercise arm follows a fixed arcing path, then the machine mechanism is simple, but the movement does not accurately simulate natural body movement and can cause improper form
Solution Approach 1:
The patent applies dynamics by allowing the exercise arm to move through a customizable range of motion that can be adjusted to match natural body movement patterns. This enables the machine to simulate natural exercise movements more accurately while maintaining a relatively simple mechanical structure.
Solution Approach 2:
The patent uses parameter changes by allowing users to adjust the range of motion and positioning parameters of the exercise arm. This enables customization of the movement path to match individual user needs and natural movement patterns without requiring complex mechanical systems.

AI summary
A press partner system facilitates the use of a plate-loaded press machine. The system comprises a press partner clamp apparatus and a press partner sleeve device or apparatus, configured for installation on the press machine to modify the range of motion of a machine arm thereof. The clamp apparatus comprises a C-shaped lower portion attachable to a side arm contact rod of the machine arm, an upper block portion, and at least one clamp block extension. The press partner sleeve device or apparatus comprises a lower skirt portion attachable to a bumper of the press machine such that the press partner lower skirt portion fits over at least a portion of the bumper and the press partner sleeve device or apparatus extends beyond the bumper. The system may include a unitary press partner sleeve device, and/or a press partner sleeve apparatus comprising a plurality of components and a securement strap.
