Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote control systems for robots, such as those using mechanical buttons or laser guiding beams, suffer from low accuracy and long response times due to the need for complex button arrangements and reliance on visual alignment, making direction control non-intuitive and prone to interference from ambient light.
Innovation Solution
A remote control system utilizing a controlled device with a light source and a remote device equipped with an image sensor and processor, which captures images of the light source to determine the moving direction and operating mode of the controlled device, allowing for simplified control via vector operations and intuitive user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical buttons or direction keys are used for remote control, then the controlled device can be operated, but the direction control is not intuitive and requires visual alignment consideration
Solution Approach 1:
The patent replaces mechanical buttons and direction keys with an image sensor-based optical recognition system. The remote controller captures images of the controlled device's light source and determines position and orientation through image processing, eliminating the need for mechanical button arrangements and providing intuitive directional control based on visual alignment.
Solution Approach 2:
The patent introduces a light source as an intermediary between the controlled device and the remote controller. The light source emits light that is captured by the image sensor, serving as a visual mediator that enables intuitive directional control without requiring complex button arrangements or direct visual alignment consideration by the user.
2Device complexity
If laser guiding beam is used to replace mechanical buttons, then button arrangement is simplified, but the system requires 360-degree panoramic scanning and is prone to interference from ambient light
Solution Approach 1:
The patent applies local quality by making the light source directional and position-specific rather than omnidirectional. The light source emits light in specific directions, and the image sensor captures images from specific angles, creating a localized optical interaction that is less susceptible to ambient light interference and does not require 360-degree scanning.
3Reliability
If 360-degree panoramic scanning is performed to capture laser guiding beam, then the controlled device can be located, but the response time is long and accuracy is reduced due to ambient light interference
Solution Approach 1:
The patent applies preliminary action by having the light source continuously emit light in predetermined directions before the control operation is initiated. The image sensor is pre-configured to capture images from specific angles, so when the user points the remote controller, the system can immediately process the captured image without requiring time-consuming 360-degree scanning, thus reducing response time while maintaining reliability.
