Motorless Treadmill Speed Indicator Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorless treadmills lack a clear indication of speed changes based on the user's location, making it difficult for users to adjust their exercise intensity effectively.
Innovation Solution
A motorless treadmill with a curved track and side covers featuring a speed-related indicator that displays speed information through differently colored and lengthened areas, allowing users to intuitively understand speed changes based on their stepping location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a motorless treadmill uses a curved track design to enable speed changes based on user location, then the treadmill becomes more compact and lightweight, but the user cannot easily understand or control the speed variations
Solution Approach 1:
The patent applies color-coded speed zones painted on the curved track surface to indicate different speed ranges. The track is divided into multiple colored sections (e.g., green for slow, yellow for medium, red for fast speeds), allowing users to visually understand and control their exercise intensity based on their position on the track without complex mechanical controls.
2Ease of manufacture
If the treadmill track is designed without separate driving means to reduce cost and size, then the treadmill becomes more affordable and compact, but the user lacks clear information about movement speed
Solution Approach 1:
The patent uses color-coded zones on the track surface to communicate speed information to users. Different colored sections correspond to different speed ranges, providing visual feedback about movement speed without requiring expensive sensors, motors, or electronic displays, thus maintaining low manufacturing costs while eliminating information loss.
Solution Approach 2:
The patent introduces visual markers (color-coded zones) as an intermediary between the mechanical track system and the user. These markers serve as a communication medium that translates the mechanical speed variations into easily understandable visual information, bridging the gap between the simple mechanical design and user awareness of speed.
3Adaptability or versatility
If the treadmill uses a curved track that changes speed by location to provide varied exercise intensity, then the exercise effectiveness increases, but the device becomes more complex
Solution Approach 1:
The patent divides the curved track into multiple segmented zones with different colors, each representing a specific speed range or exercise intensity level. This segmentation allows the track to provide varied exercise intensities through its geometry alone, without requiring complex mechanical mechanisms to actively adjust speed, thus maintaining simplicity while achieving adaptability.

AI summary
There is provided a motorless treadmill. The motorless treadmill includes: a motorless track having a curved shape such that an inclination angle increases with respect to a ground surface toward a front end and a rear end of the motorless track, and configured to move around a closed path by a user's footsteps; and a pair of side covers disposed on two opposing sides of the motorless track, wherein the motorless track changes movement speed according to a location at which the user steps on the motorless track, and wherein, on at least one side cover of the pair of side covers, a speed-related indicator is disposed to indicate information related to the movement speed of the motorless track.
