Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracked vehicles are heavy, generate significant vibration, and have difficulty running smoothly over obstacles due to their large volume and weight.
Innovation Solution
A tracked vehicle design featuring a frame with a driving mechanism, including three main supports connected by a connecting rod, an auxiliary supporting frame with a damper, and a fuel engine, which reduces weight and vibration through a triangular structure and oil brake system, along with a foldable control rod and alloy steel frame for reduced volume and improved stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional heavy-duty tracked vehicle design is used, then strong power for getting over obstacles is achieved, but the volume is relatively heavy and large vibration is generated
Solution Approach 1:
The tracked vehicle body is divided into multiple modular sections including a frame, driving mechanism, and track wheels that can be independently designed and assembled. This segmentation allows for optimization of each component's weight and function while maintaining overall structural integrity and obstacle-crossing capability
Solution Approach 2:
The patent employs composite material construction for the frame and structural components, combining materials with different properties to achieve optimal strength-to-weight ratio. This allows the vehicle to maintain strong obstacle-crossing power while significantly reducing overall weight and volume
2Force
If traditional heavy-duty tracked vehicle design is used, then strong power for getting over obstacles is achieved, but large vibration is generated and cannot run smoothly
Solution Approach 1:
The patent incorporates vibration damping elements and shock absorption mechanisms in advance within the frame structure and track wheel assemblies. These pre-installed cushioning features mitigate vibration generation before it propagates through the vehicle system, enabling smooth operation while maintaining obstacle-crossing power
Solution Approach 2:
The patent introduces intermediary components such as dampers and flexible connectors between rigid structural elements. These intermediaries absorb and dissipate vibration energy, acting as mediators that allow the vehicle to transmit necessary driving forces while filtering out harmful vibrations
3Stability of the object's composition
If three main supports with auxiliary supporting frame and damper are added, then vibration is reduced and stability is improved, but device complexity increases
Solution Approach 1:
The patent integrates the three main supports, auxiliary supporting frames, and dampers into a unified structural system where components serve multiple functions. The supports provide both structural framework and vibration damping, while the auxiliary frames contribute to both stability and shock absorption, thereby reducing overall system complexity despite added functionality
