Automatic Remote Control Pairing for Vehicle Tail Lifts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for operating tail lifts, particularly when connecting or disconnecting towing and trailer vehicles, require extensive manual configuration and risk operational errors due to the need for manual coupling of control units, which can lead to incorrect pairings with nearby vehicles.
Innovation Solution
The method automates the coupling of remote control units between towing and trailer vehicles by detecting connection parameters and using a time measurement device to ensure synchronized signal exchange within a predetermined interval, allowing wireless operation and preventing incorrect pairings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual coupling of control units is used when connecting towing and trailer vehicles, then the system can be operated, but extensive configuration measures are required and operational errors may occur
Solution Approach 1:
The system performs automatic coupling of control units through self-identification and self-pairing mechanisms. When vehicles are connected, the control units automatically detect each other, exchange identification codes, and establish wireless communication without requiring manual configuration by the operator.
Solution Approach 2:
The patent replaces manual mechanical coupling operations with automated electronic identification and wireless communication systems. The control units use electronic signal exchange and coded communication to establish connections, eliminating the need for manual pairing procedures.
2Adaptability or versatility
If manual coupling of control units is used, then the system can be configured, but the risk of incorrect pairing with nearby vehicles increases
Solution Approach 1:
The system assigns unique identification codes to each control unit and vehicle combination, creating locally specific recognition patterns. The automatic coupling process uses these unique identifiers to ensure that only the correct control unit pairs with its intended vehicle, preventing incorrect pairings with nearby vehicles.
Solution Approach 2:
The control units exchange identification signals and verify pairing status through feedback mechanisms. The system confirms successful coupling by verifying matching identification codes and maintains reliable communication only between correctly paired units, eliminating ambiguity in vehicle-control unit associations.
3Reliability
If factory-assigned control units are used for each vehicle, then coupling is predetermined, but flexibility in vehicle changes is reduced
Solution Approach 1:
The system transitions from static factory-assigned pairings to dynamic automatic identification and pairing. Control units can adapt to different vehicle combinations through automated recognition processes, allowing flexible vehicle changes while maintaining reliable coupling through real-time identification verification.
Solution Approach 2:
The control units are designed with universal compatibility through standardized identification protocols and wireless communication interfaces. A single control unit can pair with different vehicles through automatic recognition, providing multi-functionality and flexibility while maintaining reliable operation across various vehicle configurations.
