Gate Drive Bidirectional Radio Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive systems for gates, such as garage doors, lack confirmation of command receipt when operated remotely, leading to uncertainty for users about whether the command has been successfully transmitted to the gate, especially when visual contact is not possible.
Innovation Solution
Implementing a bidirectional radio transmission link between the hand-held transmitter and the radio receiver, allowing for immediate acknowledgment signals to be sent back to the user, along with a network of powered radio transmitter/receiver units that forward commands and acknowledgments, ensuring reliable operation even without direct line of sight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand-held transmitter is used to operate a gate remotely, then the ease of operation is improved, but the user cannot confirm command receipt without visual contact with the gate
Solution Approach 1:
The patent implements a feedback mechanism where the radio receiver sends an acknowledgment signal back to the hand-held transmitter when a command is received. This acknowledgment includes a code that matches the transmitted command, allowing the user to confirm that the gate has received the operation command even without visual contact.
Solution Approach 2:
Instead of the traditional unidirectional transmission from transmitter to receiver, the patent establishes a bidirectional communication link where the receiver actively responds to the transmitter with acknowledgment signals, reversing the typical information flow direction.
2Reliability
If a bidirectional radio transmission link is implemented with acknowledgment signals, then the reliability of command transmission is improved, but the device complexity increases
Solution Approach 1:
The radio transmitter/receiver units are designed to perform multiple functions: transmitting commands, receiving commands, sending acknowledgment signals, and receiving acknowledgments. This multi-functionality reduces the need for separate dedicated components for each communication direction.
Solution Approach 2:
The system automatically generates and transmits acknowledgment signals without requiring additional manual intervention or complex external verification systems. The radio receiver itself provides the confirmation service by sending back the acknowledgment code.
3Adaptability or versatility
If radio signals are forwarded through multiple network nodes to extend transmission range, then the adaptability to different locations is improved, but the loss of time for signal transmission increases
Solution Approach 1:
The acknowledgment signal is generated and transmitted immediately upon receiving the command signal, without waiting for the gate operation to complete. This preliminary acknowledgment provides immediate feedback to the user about command receipt, separate from the actual gate execution time.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to confirm command execution immediately, enhancing the ease of use and functionality by providing instant feedback, allowing for seamless operation of gates without waiting, even when out of visual range.
Implementation Method 1
A command sent by the hand-held transmitter in the form of radio signals to operate a door is acknowledged without an additional request by sending an acknowledgment signal in the form of further radio signals via the bidirectional radio transmission path to the hand-held transmitter
