Treadmill Motor Positioning Between Shafts to Reduce Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional treadmills have a large overall length and volume due to the mounting of the driving member and slope control motor at the front side relative to the front roller, resulting in excessive space occupation during packing, delivery, and storage.
Innovation Solution
The motor of the driving member is positioned between the front and rear rotating shafts, with a transmission mechanism to rotate the running belt, reducing the overall length and volume of the treadmill, and incorporating a lifter mechanism for adjustable slope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driving member and slope control motor are mounted at the front side relative to the front roller, then the treadmill can achieve the expected functional effects, but the overall length and volume of the treadmill become large, occupying much packing, delivery and storage space
Solution Approach 1:
The motor is repositioned from the front side to the space between the front and rear rollers, utilizing the lateral dimension of the treadmill structure. This dimensional redistribution allows the motor to be integrated into the internal cavity space rather than extending the front protrusion, thereby reducing overall length and volume while preserving driving functionality through the transmission member.

AI summary
A treadmill includes a frame, a driving member and a running belt. The frame includes a base, a front rotating shaft and a rear rotating shaft. The driving member has a motor and a transmission member drivable by the motor. The motor is installed between the front rotating shaft and the rear rotating shaft and is located adjacent to the front rotating shaft. The transmission member is adapted for driving the front rotating shaft to rotate. The running belt winds around the front rotating shaft and the rear rotating shaft, and is drivable by the motor to rotate relative to the base. By installing the motor between the front rotating shaft and the rear rotating shaft, an overall length and size of the treadmill is reduced for minimizing storage space.
