Remote Control Receiver Binding for Model Vehicle Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remotely controlled model vehicle systems require a matched controller and receiver, limiting their compatibility and increasing costs, as each system must be purchased complete, and users face inconvenience and expense in switching frequencies to avoid interference.
Innovation Solution
A method where a model vehicle is sold without a remote control signal source, with a preprogrammed globally unique identifier, allowing the receiver to bind with a remote control signal source, enabling a single controller to communicate with multiple model vehicles using digital spread spectrum modulation or frequency hopping spread spectrum technology, allowing for flexible frequency allocation and reducing the need for multiple controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complete model vehicle system is purchased with a matched controller and receiver, then the system is ready to operate immediately, but the cost increases significantly and compatibility with other vehicles is limited
Solution Approach 1:
The receiver is designed with a universally programmable architecture that can learn and store multiple controller signatures. This allows a single receiver to work with multiple different controllers from the same manufacturer, making the controller universally compatible across different model vehicles rather than being locked to a specific matched pair.
Solution Approach 2:
The binding process is segmented into multiple learnable slots within the receiver, allowing it to independently store signatures from different controllers. This segmentation enables the receiver to maintain compatibility with multiple controllers simultaneously without requiring a complete system repurchase.
2Reliability
If multiple model vehicles are purchased with matched controllers, then each vehicle can operate independently, but the total cost increases due to purchasing multiple expensive controllers
Solution Approach 1:
A single controller can be programmed to work with multiple receivers across different model vehicles. The controller stores multiple receiver signatures and can selectively communicate with different vehicles, allowing one controller to replace what would traditionally require multiple matched controllers.
Solution Approach 2:
The functionality of multiple matched controller-receiver pairs is merged into a single controller that can communicate with multiple receivers. This combining reduces the total number of controllers needed while maintaining the ability to operate multiple vehicles independently.
3Object-affected harmful factors
If the operating frequency is changed to avoid interference with other model vehicles, then interference is reduced, but the complexity of frequency management increases and requires manual intervention
Solution Approach 1:
The system automatically manages frequency allocation and interference avoidance without requiring user intervention. When a model vehicle enters a area with other vehicles, the system self-adjusts frequencies and coordinates channel usage autonomously, eliminating the need for manual frequency changes by the user.
4Ease of manufacture
If a controller is sold separately from the model vehicle, then the initial cost of the model vehicle decreases, but the receiver cannot be programmed to work with the controller without the binding process
Solution Approach 1:
The receiver is pre-programmed with a universal learning capability and default binding protocols before delivery. This preliminary preparation allows the receiver to automatically recognize and bind with compatible controllers through a simplified process, reducing the complexity of setup despite being sold separately.

AI summary
Methods of establishing a fully operable remotely controlled model vehicle system for a model vehicle. The method includes the steps of transferring a model vehicle, including a receiver for receiving a control signal from a remote control signal source to control operation of the model vehicle, the transfer being from a first party to a second party, and the transfer taking place without the remote control signal source, and the second party providing the remote control signal source following transfer of the model vehicle to the second party to complete the fully operable remotely controlled model vehicle system. The transfer from the first party to the second party may be a sale of the model vehicle with the receiver, but without the remote control signal source.
