Collapsible Foot Support for Stepping Exercise Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stepping exercise machines with transverse stabilizer bars occupy excessive space during storage, transportation, and packaging due to their non-collapsible design.
Innovation Solution
A stepping exercise apparatus featuring collapsible foot support device with pivotally connected feet, positioning locks, and stabilizer bars that can be folded for space-saving storage, transportation, or packaging, while maintaining stability during exercise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If transverse stabilizer bars are extended from the body to stabilize the exercise machine, then the stability of the apparatus is improved, but the space required for storage, transportation, or packaging increases
Solution Approach 1:
The stabilizer bars are designed to be dynamically adjustable between an extended stable position during exercise and a collapsed storage position. The feet can pivot between extended and retracted positions, allowing the apparatus to adapt its configuration based on whether it is in use or storage mode, thus resolving the contradiction between stability and compactness
Solution Approach 2:
The stabilizer bars are divided into multiple segments connected by pivoting joints, allowing them to be collapsed into a compact configuration for storage while maintaining full length for stability during exercise. This segmentation enables the structure to transform between extended and retracted states
2Stability of the object's composition
If the foot support device is extended with transverse bars to stabilize the machine, then the stability during exercise is improved, but the device complexity increases
Solution Approach 1:
The stabilizer bars are integrated with the foot support device, combining the stabilization function with the support structure. This merging eliminates the need for separate stabilizing components and reduces overall device complexity while maintaining stability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus effectively stabilizes the exercise machine during use while allowing for compact storage and transportation by collapsing the feet and stabilizer bars, addressing the space efficiency issue of conventional machines.

AI summary
A stepping exercise apparatus includes a body, a crank pedal mechanism and a foot support device. The crank pedal mechanism is mounted in the body and includes a crank shaft and two pedals mounted respectively on two ends of the crank shaft. The foot support device is connected to the body to support and includes two feet, two positioning locks and two stabilizer bars. The feet are respectively and pivotally connected to body between a folded position and an unfolded position. The positioning locks are respectively mounted between the body and the feet to respectively lock the feet with the body when the feet are respectively kept in the unfolded position. The stabilizer bars are respectively and transversely connected to the feet.
