Weightlifting Support Assembly With Coarse Fine Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weightlifting support assemblies lack fine adjustment capabilities, making it difficult for users to position weightlifting equipment precisely, especially when handling heavy weights, which can lead to instability and safety issues during exercises.
Innovation Solution
A weight support assembly comprising a main support mountable to an upright frame member for coarse adjustment and a secondary support movable relative to the main support for fine positioning, allowing incremental adjustments of up to one inch between predefined vertical locations, enhancing the stability and safety of weightlifting equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional support assemblies with fixed posts or hooks are used, then the structure is simple and easy to manufacture, but the positioning precision is insufficient and cannot provide fine adjustment capabilities
Solution Approach 1:
The support assembly is divided into two independent components: a main support with coarse adjustment capability and a secondary support with fine adjustment capability. This segmentation allows each component to specialize in specific adjustment ranges, achieving high positioning precision without requiring the entire system to be complex.
Solution Approach 2:
The secondary support is positioned within or attached to the main support structure, creating a nested arrangement where the fine adjustment mechanism operates within the framework established by the coarse adjustment mechanism. This nesting enables compact integration of multiple adjustment functions.
2Reliability
If only coarse adjustment is provided, then the device complexity is low, but the stability and safety during heavy weightlifting is insufficient due to inability to make precise adjustments
Solution Approach 1:
The support assembly transitions from a static fixed-position system to a dynamic adjustable system with two levels of adjustment. The main support allows coarse positioning while the secondary support enables fine tuning, creating a adaptable system that can accommodate varying weight requirements and maintain stability throughout the lifting process.
Solution Approach 2:
The system provides adjustment in two parameter dimensions: coarse adjustment for major position changes and fine adjustment for minor position corrections. This multi-level parameter adjustment enables precise positioning of weight bars at different heights, enhancing stability during heavy weightlifting operations.
3Measurement precision
If fine adjustment capability is added to conventional support assemblies, then the positioning precision improves, but the ease of operation decreases due to additional adjustment steps
Solution Approach 1:
By segmenting the adjustment function into distinct main support and secondary support components, each with its own adjustment mechanism, the system allows operators to perform adjustments in a systematic manner. The coarse adjustment handles major positioning while the secondary support handles fine tuning, making the overall operation more manageable despite the added precision requirements.
