Solution Overview
Problem
Existing treadmill lifting mechanisms require manual operation and cannot adjust the inclination angle quickly during use, necessitating users to pause their workout.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used to adjust the treadmill platform inclination, then the structure can be simple, but the adjustment speed is slow and requires pausing the workout
Solution Approach 1:
The patent replaces manual mechanical operation with an electric motor-driven lifting mechanism. The driving unit (motor) rotates the screw unit to automatically lift the treadmill platform, eliminating the need for manual cranking or pausing during workouts.
Solution Approach 2:
The patent implements a dynamic lifting system where the inclination angle can be adjusted in real-time during operation. The controlled rotation of the screw unit allows the platform to transition between different angles smoothly, enabling adjustments without stopping the workout.
2Reliability
If multiple connectors and positioning brackets are used to secure the treadmill platform, then the lifting stability is improved, but the operation becomes more complex and time-consuming
Solution Approach 1:
The patent merges the positioning bracket and connector functions into an integrated lifting base structure. The support unit with threaded sleeve combines the positioning and lifting functions, eliminating the need for separate connectors and simplifying the overall operation.
Solution Approach 2:
The screw unit automatically performs both the lifting and positioning functions when rotated by the driving unit. The threaded sleeve design allows the screw unit to self-position and secure the platform without requiring additional manual connectors or brackets.
3Volume of stationary object
If the lifting mechanism is designed to be compact and built-in, then the device volume is reduced, but the lifting force and stability may be compromised
Solution Approach 1:
The patent employs a nested structure where the screw unit is housed within the support unit, and the driving unit is integrated into the base. The threaded sleeve is positioned within the support block, creating a compact nested arrangement that maximizes space efficiency while maintaining structural integrity.
Solution Approach 2:
The patent applies local quality enhancement by concentrating the lifting force through the threaded sleeve design. The threaded sleeve's internal threading creates high friction and mechanical advantage at the critical lifting point, ensuring sufficient lifting force is generated locally without requiring a larger overall structure.

AI summary
A treadmill lifting base includes a base; a driving unit arranged on the base; a plurality of support units, at least a part of the support units being arranged on a ground surface, and including threaded sleeves; and a plurality of screw units threadedly arranged on the threaded sleeves, each of the screw units including a matching portion capable of driving the base to move synchronously. The treadmill lifting base can realize synchronous lifting of two ends on a same side of a treadmill base with a smooth, fast and reliable lifting action, and has a small-volume lifting structure, and a lifting base with a wide application range.
