Reconfigurable Chassis Layout for Narrow-Passage Mobile Platforms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Movable platforms face challenges in operational flexibility and stability due to structural design constraints, particularly when navigating through narrow passages and performing multi-scenario operations.
Innovation Solution
The movable platform incorporates a chassis with a wheel assembly that can dynamically switch between two states, allowing the actuator to move freely and optimizing space occupation, thereby enhancing operational flexibility and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the movable platform is designed with a fixed structure to meet narrow passage requirements, then the overall length and width are reduced, but the operational flexibility deteriorates
Solution Approach 1:
The wheel assembly is designed to be movable relative to the chassis body, switching between a first state (located in the outer area of the side surface) and a second state (positioned to avoid the actuator). This dynamic reconfiguration allows the platform to adapt its structure for different operational scenarios, resolving the contradiction between compact size and operational flexibility.
2Area of stationary object
If the movable platform adopts a compact structure for multi-scenario operations, then the overall dimensions are constrained, but the control flexibility deteriorates
Solution Approach 1:
The wheel assembly can dynamically switch between different positions (first state in outer area, second state avoiding actuator), enabling flexible control operations within compact dimensions. The control device manages these state transitions to maintain operational ease despite size constraints.
3Stability of the object's composition
If the wheel assembly is positioned in the outer area for stability, then the structural stability is improved, but the actuator movement space deteriorates
Solution Approach 1:
The wheel assembly dynamically switches between a first state (located in the outer area to provide stability) and a second state (positioned to avoid the actuator, providing movement space). This temporal separation of functions resolves the spatial conflict between stability and actuator operation.

AI summary
A chassis of a movable platform is provided, including a chassis body and a wheel assembly, the chassis body is configured to support an actuator of the movable platform, the wheel assembly is movably connected to the chassis body to switch between a first state and a second state, in the first state, all or part of the wheel assembly is located in an outer area of a side surface of the chassis body, and in the second state, the wheel assembly is positioned to avoid the actuator, so as to allow the actuator to move to the outer area of the side surface of the chassis body to perform a corresponding operation. A movable platform including the chassis is also provided to enhance the operational flexibility of the movable platform and improve the overall operational stability of the platform.
