Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stationary exercise apparatuses lack variety in exercise experience and intensity, relying primarily on speed adjustments and limited incline variations to enhance workout intensity.
Innovation Solution
A stationary exercise apparatus with a movable frame and adjustable swing axis, allowing pedals to move along a closed loop path with variable shapes, providing adjustable incline and stride length for enhanced exercise intensity and gluteus engagement, while maintaining a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If exercise intensity is increased by adjusting apparatus speed, then exercise intensity is improved, but exercise variety and engagement are limited
Solution Approach 1:
The patent implements dynamic adjustment of the footpath geometry through movable supporting members that can change the incline and stride length during exercise. This allows the exercise intensity and variety to be varied dynamically rather than being fixed, resolving the contradiction between maintaining consistent intensity and providing exercise variety.
Solution Approach 2:
The patent changes the geometric parameters of the footpath (incline angle, stride length) by adjusting the position of supporting members and pivot points. This enables diverse exercise experiences without relying solely on speed adjustments, addressing both exercise intensity and variety requirements.
2Power
If incline and stride length are adjusted to enhance exercise intensity, then exercise effectiveness is improved, but device complexity increases
Solution Approach 1:
The movable supporting members serve multiple functions: they adjust incline, modify stride length, and define the footpath geometry all through a single mechanical structure. This multi-functionality reduces the need for separate mechanisms for each adjustment, thereby limiting device complexity while achieving enhanced exercise intensity.
Solution Approach 2:
The footpath geometry is segmented into adjustable components (supporting members, pivot points) that can be independently positioned. This segmentation allows complex geometric adjustments to be achieved through simple, modular mechanical elements rather than a single complex mechanism.
3Device complexity
If fixed footpath geometry is used to simplify device structure, then device complexity is reduced, but exercise variety and intensity are limited
Solution Approach 1:
The patent transitions from fixed to dynamic footpath geometry by implementing movable supporting members that can be repositioned during exercise. This dynamic capability provides exercise variety and intensity modulation without requiring complex control systems, maintaining structural simplicity while enhancing adaptability.
