Foldable Power Cage With Guided Weights for Compact Leg Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bodybuilding equipment for home use is inadequate for small spaces, lacking essential features for lower body muscle development and requiring excessive space and weight capacity, making it impractical and costly for professionals.
Innovation Solution
A foldable multifunctional training equipment with a collapsible power cage, adjustable seat, and removable tools for 45° leg press, leg extensions, and lying femoral curl, using guided weight towers and pulleys to minimize space while providing sufficient load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If professional leg press equipment is used, then sufficient load capacity and exercise effectiveness are achieved, but the equipment occupies excessive space (200-250 cm length, 140-150 cm height, 70-190 cm width) making it unfeasible for home use
Solution Approach 1:
The patent implements a nested structure where the leg press platform and weight system are integrated within the power cage framework. The guided bar and weight towers are positioned inside the cage structure, allowing the entire leg press mechanism to be contained within a compact footprint that fits home environments while maintaining professional load capacity.
Solution Approach 2:
The power cage is designed as a multi-functional platform that serves both as a structural support for heavy leg press exercises and as a framework for other training exercises. The guided bar and adjustable components allow the same structure to accommodate different exercise types, eliminating the need for separate dedicated equipment for each exercise.
2Adaptability or versatility
If multiple separate machines for lower body exercises are purchased, then complete lower body training is achieved, but the cost and total volume increase significantly
Solution Approach 1:
The power cage incorporates multiple lower body exercise capabilities within a single structure. The adjustable leg press platform can be reconfigured for different exercises including squats, lunges, and calf raises, while the guided bar system supports various barbell exercises, providing comprehensive lower body training coverage without requiring separate machines.
Solution Approach 2:
The patent merges previously separate exercise functions into a unified power cage system. The leg press mechanism, guided barbell system, and weight towers are combined into one integrated structure, allowing users to perform multiple lower body exercises with a single piece of equipment rather than requiring separate machines for each exercise type.
3Volume of moving object
If foldable power cages are used to reduce space, then volume is decreased, but the structure cannot expand with additional accessories and remains limited to specific exercises
Solution Approach 1:
The power cage employs dynamic, adjustable components including height-adjustable leg press platforms, reconfigurable guided bar positions, and adjustable weight tower configurations. These dynamic elements allow the structure to be adapted for various exercises and accommodate additional accessories as training needs evolve, while maintaining a compact foldable form when not in use.
