Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weight training sleds are not suitable for indoor use due to abrasion and lack of versatility in training forms, with wheeled versions providing limited resistance options.
Innovation Solution
A weight training device that can transform into a hand truck, featuring a main frame with rotating wheels, adjustable operating parts, and a damping structure to provide resistance, allowing for multiple training modes by configuring operating parts on different tubes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a weight training sled uses a sliding plate that contacts the ground, then friction provides resistance for training, but abrasion and wearing occur making it unsuitable for indoor use
Solution Approach 1:
The patent introduces wheels as an intermediary between the sliding plate and the ground. The sliding plate is fitted with four wheels that contact the ground instead of the plate itself, eliminating direct friction and wear between the plate and floor surface while still enabling resistance-based training through the wheel mechanism
2Object-affected harmful factors
If a weight training sled is equipped with wheels to eliminate ground contact, then indoor use becomes suitable, but training form diversity is limited
Solution Approach 1:
The operating part is divided into multiple segments including a first operating portion, second operating portion, and connecting portion. This segmentation allows different portions to be selectively positioned on various tubes (first tubes, second tubes, third tubes) to create multiple training configurations and forms
Solution Approach 2:
The operating part is designed as a multi-functional component that can be configured in multiple positions and orientations. By selectively positioning different operating portions on different tubes, a single operating part can provide multiple training forms including pushing, pulling, and resistance training variations
3Force
If multiple heavy objects are loaded on the main frame, then training resistance increases, but the device becomes harder to move and manipulate
Solution Approach 1:
The patent introduces a vertical dimension by allowing the main frame to be tilted and rotated. The second operating portion can be positioned to enable lifting and tilting actions, transforming the movement from purely horizontal to multi-dimensional, which helps overcome the difficulty of moving heavy loaded frames

Function Achieved in This Case
Enables versatile weight training by offering various grip and movement options, reducing wear and tear, and allowing for diverse training forms, making it suitable for indoor use.
Implementation Method 1
a damping structure, configured on the main frame, the damping structure is connected to the second wheel, so as to provide resistance against the rotation of the second wheel

AI summary
Disclosed is a weight training device that can be transformed into a hand truck. The device includes a main frame, two first wheels, a second wheel, two first installing tubes, two second installing tubes and two operating parts, wherein the main frame is used for loading at least one heavy object. Each wheel is fitted on the main frame in a rotational manner, so that the main frame can be moved through the rolling of the wheels. Each of the first installing tubes are opposite each other and respectively extends upward. Each of the second installing tubes are opposite each other and respectively extend away from the main frame. Each of the operating parts are opposite each other in the lateral direction and are respectively and selectively configured on each of the first or each of the second installing tubes, so as to shift the operating mode of weight training.
