Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices with wheels, such as robots or vehicles, face stability issues on complicated or uneven terrain, affecting their ability to maintain contact and carry cargo effectively.
Innovation Solution
A rocking arm structure with a shaft assembly connecting two wheel assemblies, allowing the arm body to rotate around the shaft, enabling the wheels to revolve in the same direction and adapt to terrain changes without the need for additional sensors, thus enhancing stability and self-steering capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional wheel structures are used on devices, then the device can move on flat terrain, but the stability deteriorates on complicated or uneven terrain
Solution Approach 1:
The patent applies the dynamics principle by making the wheel assembly movable relative to the device body through a rocking arm mechanism. The wheel assembly can rock back and forth around a shaft assembly, allowing it to dynamically adapt to uneven terrain while maintaining device stability. This transforms the static wheel mounting into a dynamic system that automatically adjusts to terrain variations.
Solution Approach 2:
The patent segments the wheel support function by introducing a separate rocking arm structure that connects the wheel assembly to the device body. This segmentation allows the wheel assembly to independently adjust its position relative to the main body, improving adaptability to terrain while the main body maintains its stability.
2Adaptability or versatility
If sensors are added to detect terrain changes, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent applies the self-service principle by designing a passive rocking arm mechanism that automatically adapts to terrain changes without requiring active sensing or control systems. The mechanical structure itself performs the terrain adaptation function through its inherent degrees of freedom, eliminating the need for additional sensors and complex control electronics.
Solution Approach 2:
The patent replaces electronic sensing and control systems with a purely mechanical rocking arm mechanism. The terrain adaptation is achieved through mechanical means rather than electronic sensors and actuators, simplifying the overall device complexity while maintaining adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
A rocking arm structure includes an arm body, a first wheel assembly connected to the arm body, a second wheel assembly connected to the arm body, and a shaft assembly disposed between the first wheel assembly and the second wheel assembly. The arm body can rotate relative to the main body around the shaft assembly, and drive the first wheel assembly and the second wheel assembly to revolve in a same direction around the shaft assembly. The first wheel assembly and the second wheel assembly are both steering wheel assemblies or both directional wheel assemblies.
