Integrated Treadmill Upper Limb Weight Training Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise machines occupy space and require separate equipment for training upper and lower limbs, limiting simultaneous training and efficiency in limited time settings.
Innovation Solution
An exercise machine integrating a treadmill body with an upper limb weight training mechanism featuring a guide rail, slider, and adjustable weight unit, allowing for straight pull-up and down motion to train upper limbs while increasing lower limb training strength, with the weight unit's fixing rod inclined to prevent plate fall and handle grip aligned with treadmill motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate exercise machines are used for upper and lower limb training, then each machine can be optimized for its specific function, but more space is occupied and training time increases
Solution Approach 1:
The patent combines a treadmill for lower limb training and a weight training machine for upper limb training into a single integrated exercise machine. The weight training mechanism is mounted on the treadmill frame, allowing both upper and lower limb exercises to be performed simultaneously or separately, thereby saving space and increasing training efficiency.
Solution Approach 2:
The integrated exercise machine serves multiple functions: it can be used as a treadmill for lower limb cardio exercise and as a weight training machine for upper limb strength training. The weight training mechanism includes adjustable weight plates and a guide rail system that enables versatile upper limb exercises while maintaining the treadmill functionality.
2Ease of operation
If a pivotable swing arm is used for weight training on treadmill, then space is saved, but the hand moves in a curved path which is less ergonomic
Solution Approach 1:
The weight training mechanism is segmented into distinct functional components: a guide rail system that provides straight vertical motion, a slider that moves along the guide rail, and a weight plate assembly. This segmentation allows the hand to move in a straight ergonomic path while the internal mechanism handles the complexity of motion control.
Solution Approach 2:
The guide rail acts as an intermediary element between the weight plate and the user's hand. It constrains the motion to a straight vertical path, ensuring ergonomic hand movement while the slider mechanism handles the complexity of translating the user's pull motion into weight lifting action.

AI summary
An exercise machine includes a treadmill body and an upper limb weight training mechanism. The upper limb weight training mechanism includes a guide rail, a slider, and a weight unit. The guide rail is fixedly connected to the treadmill body. The slider is connected to the guide rail and is movable upwards and downwards on the guide rail. The slider is provided with a handle. The weight unit is disposed on the slider. The upper limb weight training mechanism can be pulled straight up and down to train upper limb muscles of a user while lower limb muscles of the lower limbs of the user are trained.
