Problem
Current methods for testing remote control units are inefficient and incomplete, requiring significant human effort and multiple devices to verify the functionality of sophisticated remote control units, especially when testing IR and RF remote control codes and voice commands, which is time-consuming and often incomplete.
Innovation Solution
A universal test station equipped with a test fixture that securely holds the remote control unit and uses solenoids to simulate button presses, combined with IR and RF receivers, light sensors, and a microphone to automatically test various functions, including IR and RF code transmission, status indicators, and voice command functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual testing methods are used with multiple devices, then comprehensive testing of remote control functions can be achieved, but significant human effort and time are required
Solution Approach 1:
The patent replaces manual mechanical button pressing with automated solenoid actuators that mechanically press buttons. The manual testing process is substituted with an automated system comprising a test fixture, solenoids aligned with buttons, and a controller that coordinates button presses and signal reception, thereby eliminating human effort while maintaining comprehensive testing capability
Solution Approach 2:
The patent introduces an intermediary automated testing system between the remote control unit and the testing process. This intermediary system includes a controller that manages the entire testing sequence, solenoids that interact with buttons, and receivers that capture signals, replacing the need for direct human interaction with multiple testing devices
2Reliability
If multiple devices are used for testing remote control functions, then comprehensive functionality verification is possible, but device complexity and setup requirements increase
Solution Approach 1:
The patent merges multiple testing functions into a single integrated test station. The test fixture combines button actuators (solenoids), signal receivers (IR and RF), light sensors for status indicators, and a control system into one unified device, eliminating the need for multiple separate testing devices while maintaining comprehensive functionality verification
Solution Approach 2:
The test station is designed as a universal testing system capable of verifying multiple remote control functions through a single device. It can test button presses, IR and RF signal transmission, status indicators, and other functions, replacing the need for specialized devices for each testing function
3Productivity
If automated testing is implemented, then testing efficiency and speed are improved, but the complexity of the testing system increases
Solution Approach 1:
The automated testing system is segmented into distinct functional modules: a test fixture for physical positioning, solenoids for button actuation, receivers for signal capture, light sensors for indicator detection, and a controller for coordination. This segmentation allows each component to perform a specific function efficiently, achieving high testing speed while managing complexity through modular design
Solution Approach 2:
The controller serves as an intermediary that coordinates all automated testing operations. It manages the sequence of button presses, triggers signal reception, and processes test results, enabling automated high-speed testing while centralizing the complexity in a single control unit rather than distributing it across multiple complex devices
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
The test station enables rapid, thorough, and accurate testing of remote control units, ensuring they are functioning properly and suitable for reuse, reducing the need for extensive human intervention and multiple devices.

The test fixture further comprises a plurality of actuators, such as solenoids, that are aligned with buttons on the remote control unit and capable of pressing each of the buttons
Implementation Method 2
The station further comprises receivers for receiving infrared (IR) and radio frequency (RF) remote control codes that are transmitted by the remote control unit
Implementation Method 3
a test station can further comprise sensors capable of detecting the color of light emitted by one or more status indicators on the remote control unit
