Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheel designs face limitations in weight, size, material, manufacturing process, airflow, resistance to foreign objects, imperfections, pressure, temperature, and puncture, while also being heavy and prone to air leaks.
Innovation Solution
A rolling brace system replaces the traditional wheel hub and spoke system, incorporating a soft inner rubber layer and rollers for stability and stiffness, with a cylindrical rim and hydraulic braking mechanism, allowing for larger wheel sizes and improved durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pneumatic tire is used, then the wheel can absorb road vibration and have a larger contact surface, but it is prone to air leaks and punctures
Solution Approach 1:
The patent changes the physical state of the tire filling material from gas (air) to solid granular material. This parameter change eliminates air leaks and punctures while maintaining the tire's ability to conform to road surfaces. The solid material provides both structural support and vibration absorption without the weaknesses of pneumatic tires.
Solution Approach 2:
The patent uses a composite structure combining a rigid rim with flexible tire layers and solid granular filling material. This composite approach integrates the strengths of different materials: the rim provides structural integrity, the tire layers provide flexibility and protection, and the solid granular material provides vibration absorption and support, achieving both reliability and ease of operation.
2Stability of the object's composition
If a solid tire is used, then the wheel gains stability and stiffness, but it increases weight and reduces pliability
Solution Approach 1:
The patent segments the tire structure into multiple functional layers (tread layer, body layers, reinforcement layers) and fills the interior with granular material. This segmentation allows each layer to perform its specific function while the granular filling provides overall support, achieving stability without requiring a completely solid construction that would increase weight.
Solution Approach 2:
The patent employs a porous or partially filled structure rather than a completely solid tire. The granular material filling creates a porous-like structure that provides structural support and stability while allowing for weight reduction compared to a fully solid tire construction.
3Strength
If a wheel hub and spoke system is used, then the wheel can support the vehicle weight, but it increases device complexity and weight
Solution Approach 1:
The patent extracts and eliminates the traditional wheel hub and spoke system, replacing it with a simplified rim structure and solid granular filling. The granular material assumes the load-bearing function previously performed by the hub and spoke assembly, reducing structural complexity while maintaining load-bearing capacity.
Solution Approach 2:
The patent merges the functions of the hub, spokes, and rim into a single integrated rim structure filled with granular material. This consolidation eliminates the need for separate hub and spoke components, reducing device complexity while the granular filling provides the necessary structural support for load bearing.
