Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing model vehicle receivers are limited by mirroring the average frame frequency of input pulses in their output servo control pulses, which restricts servo response time and torque, especially when higher repetition frequencies are required.
Innovation Solution
A system and method that allow for generating servo control pulses at a programmable output pulse repetition frequency different from the average input frame frequency, utilizing a receiver with a communication module and processing module to decode input pulses and output servo control pulses at a programmed frequency.

Engineering Contradiction Analysis
1Speed
If the receiver mirrors the average frame frequency of input pulses in the output servo control pulses, then the system maintains simple frequency mapping, but the servo response time and output torque are restricted
Solution Approach 1:
The receiver dynamically adjusts the output pulse repetition frequency independently from the input frame frequency. The microprocessor generates servo control pulses at a programmable output frequency that can be higher than the input frame frequency, allowing the system to optimize servo response time without being constrained by the transmitter's frame rate. This dynamic frequency decoupling enables faster servo response while maintaining simple frequency mapping through software control.
2Force
If the receiver operates at the average frame frequency of input pulses, then the system maintains consistent timing with the transmitter, but the output torque is limited
Solution Approach 1:
The receiver implements preliminary action by buffering and storing input pulse data before generating output servo control pulses. The microprocessor accumulates input pulse information over multiple frames and then generates the servo control pulses at the optimized output frequency. This preliminary data collection and processing allows the system to maintain accurate timing information from the transmitter while decoupling the output frequency to maximize output torque and servo performance.
3Reliability
If the receiver uses a microprocessor for filtering and fail-safe features, then the system provides enhanced reliability, but the output pulse repetition frequency is still constrained by the input frame frequency
Solution Approach 1:
The receiver implements parameter changes by allowing the output pulse repetition frequency to be independently programmed and adjusted from the input frame frequency. The microprocessor maintains fail-safe monitoring and filtering functions while simultaneously generating servo control pulses at an optimized frequency. This parameter independence enables the system to achieve both high reliability through software-based fail-safe features and high-speed performance through optimized output frequency, resolving the contradiction between reliability and speed.

AI summary
Systems and methods are provided for controlling one or more servos coupled to a model vehicle. An input signal having a series of input pulses encoded at an input pulse repetition frequency is received at a receiver coupled to a model vehicle having one or more servos. The input signal is decoded at the receiver. A servo control pulse is generated using at least one of the input pulses at the receiver. The servo control pulse is outputted to at least one of the servos at an output pulse repetition frequency that is different from the input pulse repetition frequency.
