Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weight sleds face challenges in indoor use due to space constraints and instability when converted to wheeled versions, requiring additional space or loss of stability, and there is a need for a compact, lighter weight wheeled weight training sled that can be efficiently stored and used in confined areas.
Innovation Solution
A wheeled weight training sled with rotatable wheels, a braking mechanism, pivotable push handles, and a wall hanging bracket set that allows for vertical stowage, enabling efficient use and storage in limited spaces while maintaining stability and allowing for adjustable resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional weight sleds with skids are used, then frictional resistance is provided for exercise, but substantial open space is required and flooring damage occurs due to abrasive sliding
Solution Approach 1:
The patent replaces the traditional skid-based friction system with a wheeled mechanism that uses a brake system to provide resistance. Instead of relying on friction between skids and the ground, the invention uses wheels for movement and a brake mechanism (such as a drum brake or disc brake) to create controlled friction that provides exercise resistance, thereby eliminating the need for large open spaces and protective flooring.
2Object-affected harmful factors
If wheeled version of blocking sleds is used, then frictional skidding is eliminated, but stability is lost when pushing the sled
Solution Approach 1:
The patent employs dynamic elements including spring-loaded suspension systems that adjust to user weight and movement, and push handles that can pivot or adjust in position during exercise. These dynamic features allow the sled to adapt to the user's movements, maintaining stability while eliminating the harmful frictional skidding of traditional designs.
Solution Approach 2:
The invention changes key parameters of the sled system by introducing adjustable components such as variable resistance mechanisms (e.g., adjustable brake tension, removable weight plates) and configurable push handle positions. These parameter changes allow the sled to maintain optimal stability for different users and exercise intensities while using wheels instead of skids.
3Stability of the object's composition
If stable wheeled weight training sleds are used, then stability is improved, but the sled is not compact and lighter weight
Solution Approach 1:
The patent divides the sled into separate modular components including the frame, wheels, brake system, weight plates, and push handles. This segmentation allows users to remove unnecessary components (such as weight plates or push handles) to reduce overall weight when full stability is not required, while maintaining stability when all components are assembled for intensive training.
Solution Approach 2:
The invention uses dynamic elements such as collapsible or removable push handles, and adjustable wheel configurations that allow the sled to be compacted or disassembled for storage and transport, reducing its effective weight and footprint while maintaining full stability during actual use.

AI summary
A weight training sled and wall hanging bracket set for supporting the weight training sled in an elevated vertical stowage position. The push handles on the sled are pivotable as a unit about a laterally extending pivot axis as between an upward use position and a lowered stowage position extending towards the second longitudinal end of the chassis. The wall hanging bracket set includes an upper bracket for attachment to a vertical surface and supportively contact a second longitudinal end of the sled at two laterally spaced contact points, and a lower bracket for attachment to the vertical surface and supportively contact a first longitudinal end of the sled at a single contact point.
