Bounce Treadmill Segmented Belt Elastic Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional treadmills lack a bouncing function, which can make running less engaging and less effective in terms of comfort and diversity in exercise modes.
Innovation Solution
A bounce treadmill design featuring a base with a drive mechanism and a running belt system composed of fixed seats, elastic elements, and a running belt piece, where the elastic elements provide an upward force upon deformation, allowing for a bouncing effect when stepped on, and complementary surfaces on adjacent running belt pieces prevent gaps from forming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional rigid running belt is used, then the treadmill structure is simple and stable, but the running comfort is poor and lacks bouncing function
Solution Approach 1:
The running belt is divided into multiple independent running belt pieces (first, second, third pieces) instead of a single rigid belt. Each piece can independently deform and bounce, providing better comfort while maintaining structural manageability through modular segmentation
Solution Approach 2:
The running belt pieces are designed as flexible components that can deform under user weight. The elastic elements (springs or elastic bands) embedded in each piece provide the necessary flexibility and bouncing function, replacing the traditional rigid belt structure
2Ease of operation
If elastic elements are added to provide bouncing function, then running comfort improves, but the risk of foot sinking between belt pieces increases
Solution Approach 1:
The lateral surfaces of adjacent running belt pieces are designed with complementary shapes (convex and concave surfaces) that fit together. This local geometric design ensures that when pieces deform independently, their surfaces interlock to prevent gaps from forming, eliminating the foot sinking risk while preserving bouncing functionality
Solution Approach 2:
Adjacent running belt pieces have asymmetric complementary surfaces (one convex, one concave) rather than identical surfaces. This asymmetric design ensures proper engagement between pieces during deformation, preventing separation and maintaining continuous surface for user safety
3Adaptability or versatility
If multiple running belt pieces are used to form the running belt, then the bouncing function is achieved, but the manufacturing complexity increases
Solution Approach 1:
The running belt is segmented into multiple identical or similar running belt pieces, each containing elastic elements. This modular approach allows for standardized manufacturing of individual pieces that can be assembled together, reducing overall manufacturing complexity despite the multi-piece configuration
Solution Approach 2:
Multiple running belt pieces are combined to form the complete running belt assembly. The pieces work together as an integrated system, sharing the bouncing function and distributing the mechanical loads, which simplifies the overall design compared to creating a single complex bouncing belt
Applied Scientific Principles
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 bounce treadmill enhances user experience by providing a comfortable and diverse exercise mode with a bouncing function, improving the overall running experience by incorporating a cushioning effect and preventing foot sinking between belt pieces.
Implementation Method 1
the elastic element provides an upward elastic force to form a buffering effect, so that the running belt has a bouncing function at the same time
