Offset Weight Support Assembly for Reduced Arm Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weightlifting devices do not efficiently utilize the weight distribution to enhance workout efficiency, as weights are typically positioned in the same plane as the user's hands, requiring excessive rotation to engage muscles effectively.
Innovation Solution
An offset weight support assembly is designed to position weights away from the handle, using a pivot arm and triangular brace structure to distribute weight load efficiently, allowing quicker muscle engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If weights are positioned in the same plane as the user's hands opposite the handles (linear design), then the structure is simple and easy to manufacture, but the workout efficiency is low and requires excessive arm rotation
Solution Approach 1:
The patent applies dimensionality change by moving weights from the same plane as the user's hands (linear arrangement) to an offset position in a different spatial plane. The weight support assembly extends perpendicular to the handle bar, positioning weights above or below the handle level, creating a three-dimensional configuration that reduces the need for arm rotation and improves workout efficiency
Solution Approach 2:
The patent employs asymmetry by introducing an offset between the weight support assembly and the handle bar, breaking the symmetric linear alignment. The weight support assembly is positioned at an offset distance from the handle bar, creating an asymmetric configuration that allows weights to be positioned out of the user's direct line of motion, thereby improving muscle engagement efficiency
2Productivity
If weights are positioned out in front of and away from the weight rack above the handles (offset design), then muscle engagement is faster and workout efficiency is improved, but the attachment and detachment process becomes more complex
Solution Approach 1:
The patent applies dynamics by designing a pivot arm mechanism that allows the weight support assembly to be dynamically attached and detached from the weight rack. The pivot arm can rotate between a stored position (when not in use) and an operational position (when weights are attached), enabling easy attachment and detachment while maintaining the offset weight positioning for improved workout efficiency
Solution Approach 2:
The patent employs segmentation by dividing the weight support system into separate modular components: the handle bar, the weight support assembly, and the pivot arm mechanism. This segmentation allows the weight support assembly to be independently attached and detached from the handle bar through the pivot arm, simplifying the attachment process while maintaining the offset configuration for improved productivity
3Loss of time
If weights are positioned out in front of and away from the weight rack above the handles (offset design), then the work out period is shortened, but the structural connection to the weight rack becomes more complex
Solution Approach 1:
The patent applies dynamics by using a pivot arm mechanism that enables the weight support assembly to be quickly attached and detached from the weight rack. The pivot arm can rotate between a stored position and an operational position, allowing rapid setup and teardown of the weight configuration, thereby minimizing time loss while maintaining the offset weight positioning
Solution Approach 2:
The patent employs preliminary action by designing the pivot arm mechanism to be pre-positioned and ready for quick attachment. The pivot arm is prepared in advance with the appropriate mounting features, allowing the weight support assembly to be rapidly attached to the weight rack without requiring complex assembly procedures, thus reducing the time required for setup while maintaining the efficient offset weight configuration
