Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art traction assemblies for wheeled vehicles are complex, costly, and inefficient due to the need for heavy and expensive ball bearing cages and lack of modularity in design, which affects manufacturing and assembly costs.
Innovation Solution
A traction assembly using a longitudinally extending endless track with a sprocket wheel, idler and road wheels, and a guide rail coupled via a frame, eliminating the need for ball bearing cages and featuring a modular design with a track tensioning system for easier assembly and reduced costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ball bearing cages are used in prior art traction assemblies, then the wheels can rotate smoothly, but the device becomes complex and expensive
Solution Approach 1:
The patent removes the ball bearing cages from the wheel assemblies entirely. Instead of using complex bearing mechanisms, the invention uses a simplified wheel design that rotates directly on the track without requiring intermediate bearing components, thereby eliminating structural complexity while maintaining rotational functionality
Solution Approach 2:
The invention replaces expensive, complex ball bearing cages with simpler, more economical wheel designs that achieve the same rotational function through direct contact with the track, reducing both manufacturing cost and structural complexity
2Ease of operation
If ball bearing cages are used in prior art traction assemblies, then the wheels can rotate smoothly, but the manufacturing and assembly costs increase
Solution Approach 1:
By extracting and removing the ball bearing cages from the design, the patent eliminates the need for complex manufacturing processes and expensive assembly operations, directly reducing manufacturing and assembly costs while preserving wheel rotation functionality
Solution Approach 2:
The invention adopts simpler, more cost-effective wheel designs that can be manufactured and assembled more easily, replacing expensive bearing components with economical alternatives that achieve the same operational result
3Device complexity
If traditional non-modular design is used in prior art traction assemblies, then the structure may be simple, but the manufacturing and assembly costs increase
Solution Approach 1:
The patent divides the traction assembly into modular components including separate track sections, wheel assemblies, and frame elements that can be manufactured independently and assembled systematically, reducing overall manufacturing and assembly costs through standardized modular construction
Solution Approach 2:
The modular components are designed with universal interfaces and standardized features that allow them to be used in multiple configurations and applications, reducing per-unit manufacturing and assembly costs through economies of scale and standardized production processes
