Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise devices have limited range of positions for the frame, bench, and cable-pulley system, requiring multiple steps to reposition adjustable components and only allowing resistance level adjustment without varying the force curve.
Innovation Solution
An exercise device with an adjustable bench assembly, multi-axis release locking mechanism, and a resistance system that allows selection of resistance levels and force curves through a transmission system with multiple resistance packs, enabling various exercises and accommodating different user sizes and shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame, bench, and cable-pulley system are made adjustable to accommodate different user sizes and exercise positions, then the adaptability and versatility of the exercise device is improved, but the device complexity and the number of adjustment steps required increase
Solution Approach 1:
The patent combines multiple adjustment functions into integrated assemblies. The bench assembly integrates seat position adjustment, backrest angle adjustment, and height adjustment into a single coordinated mechanism. The arm assemblies integrate position adjustment and locking functions, allowing users to modify multiple parameters simultaneously rather than through separate sequential steps.
Solution Approach 2:
The adjustable components are designed with multi-functionality to serve multiple purposes. The bench assembly can accommodate various exercise positions (seated, lying, inclined) and user sizes through a universal adjustment mechanism. The arm assemblies can be positioned for different exercises and user body types using the same adjustment system, reducing the need for multiple specialized components.
2Adaptability or versatility
If the resistance system only provides fixed resistance levels, then the device complexity is reduced, but the adaptability to different exercise requirements and force curves is limited
Solution Approach 1:
The resistance system is segmented into multiple independent resistance packs that can be selectively combined. Each resistance pack provides a specific resistance level or force curve characteristic, and users can assemble different resistance configurations by selecting and combining appropriate packs. This modular segmentation allows for varied resistance profiles without requiring a completely complex resistance mechanism.
Solution Approach 2:
The resistance system enables parameter changes by allowing users to select different resistance packs with varying force curve characteristics. Users can modify resistance levels and force curve profiles (e.g., constant resistance, progressive resistance, regressive resistance) by changing which resistance packs are engaged, providing adaptability for different exercise requirements without complex mechanical adjustments.
