Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving robots rely solely on mechanical spring dampers and lack effective control mechanisms, making it difficult to respond to varying driving routes and maintain stable driving, especially when encountering unforeseen obstacles.
Innovation Solution
A driving apparatus equipped with a body part, driving parts, actuating parts, and an information collection part that collects vibration information to provide vibration cancellation information, enabling the driving parts to perform adjustable operations such as rolling, yawing, and pitching to cancel shocks and respond to irregular obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical spring dampers are used for shock cancellation, then the structure is simple, but the response to varying driving routes is insufficient and stability is poor
Solution Approach 1:
The patent implements a feedback control system where sensors detect vibration information from the driving route, the controller processes this information to generate vibration cancellation commands, and the driving parts adjust their operations accordingly. This closed-loop feedback mechanism enables the system to actively respond to varying driving conditions and maintain stability, overcoming the limitations of passive mechanical spring dampers.
Solution Approach 2:
The patent transitions from static mechanical spring dampers to a dynamic control system where driving parts can perform adjustable operations (rolling, yawing, pitching) based on real-time vibration information. This dynamic adaptation allows the system to optimize its shock cancellation performance for different driving routes and conditions, significantly improving driving stability.
2Reliability
If driving parts perform adjustable operations (rolling, yawing, pitching) to cancel vibrations, then shock cancellation effectiveness is improved, but physical interference with other components may occur
Solution Approach 1:
The patent applies local quality by providing movement restricting bodies at specific locations to constrain driving parts in particular directions while allowing freedom in other directions. This selective restriction enables the driving parts to perform necessary adjustable operations for shock cancellation while preventing physical interference with other components in the system.
Solution Approach 2:
The patent segments the control of driving parts by using movement restricting bodies that independently constrain different degrees of freedom. This segmentation allows each driving part to perform its specific adjustable operations (rolling, yawing, or pitching) without causing unwanted physical interference with other components, enabling precise control over the shock cancellation mechanism.
3Speed
If vibration cancellation information is generated based on real-time vibration data, then response to unforeseen obstacles is quick, but the system complexity increases
Solution Approach 1:
The patent implements self-service by enabling the system to automatically detect vibration information, process it through the controller to generate vibration cancellation commands, and execute the necessary driving part adjustments without external intervention. This self-contained information processing and control mechanism enables quick response to unforeseen obstacles while keeping the system architecture relatively simple and integrated.
