Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controllers require users to manually control multiple devices, which is inconvenient and inefficient, and there is a need for a solution to simplify the control of a plurality of devices with a single remote controller.
Innovation Solution
A remote controller equipped with three-dimensional accelerometer components that detects user actions and orientations, allowing it to transmit corresponding commands to various devices such as window blinds, lighting fixtures, and audio/video equipment, enabling control through predefined actions and reducing power consumption by entering standby mode when stationary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated remote controller is provided for each controlled device, then the control reliability is improved, but the device complexity and quantity increase
Solution Approach 1:
The remote controller is designed to control multiple different types of devices (TV, VCR, DVD player, etc.) through a single universal controller. The controller includes a processor that can identify different device types and transmit appropriate signals, eliminating the need for separate dedicated controllers for each device while maintaining reliable control functionality.
2Device complexity
If a single remote controller controls multiple devices, then the device complexity is reduced, but the ease of operation deteriorates due to needing to select correct devices
Solution Approach 1:
The remote controller automatically identifies the target device and selects the appropriate control mode without requiring manual intervention. When the user points the controller at a device, the processor automatically detects the device type through infrared recognition and configures the control signals accordingly, making the multi-device control as easy as pointing and pressing buttons.
3Speed
If the remote controller continuously monitors and processes user actions, then the responsiveness is improved, but the power consumption increases
Solution Approach 1:
The accelerometer and processor operate in a periodic monitoring mode rather than continuously. The system periodically checks for user actions and device presence, processes signals only when actions are detected, and enters low-power states between active periods. This maintains responsive control when needed while significantly reducing average power consumption during idle periods.

Function Achieved in This Case
Enables efficient and intuitive control of multiple devices using a single remote controller, reducing the need for multiple controllers and minimizing power consumption, while supporting learning modes and command mapping for enhanced functionality.
Implementation Method 1
A remote controller senses motion on the remote controller through an accelerometer. Accelerometer information is processed to determine the orientation of the remote controller in order to control a selected controlled device from a plurality of controlled devices.

AI summary
The present invention supports the control of a plurality of controlled devices. With three dimensional accelerometer components, detection of a user action on a remote controller and the orientation of the remote controller are viable through small electronic devices. Aspects of the invention are based on the three dimensional accelerometer components to provide a remote controller that can detect the user action. Based on the user action, the remote controller transmits a signal to the controlled device which conveys the corresponding command. A selected controlled device may be matched to the remote controller. The remote controller and controlled device may also support a learning mode, in which the controlled device sends a list of supported commands to the remote controller. The remote controller then matches an associated action with each command in the command list.
