Rotatable Sensor Positioning in Spherical Electronic Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The difficulty in accessing the sensor on a spherical electronic device due to its rolling motion makes it challenging for users to provide touch inputs effectively.
Innovation Solution
The sensor is positioned and maintained in a way that it can be easily touched by the user, improving usability through controlled movements of the device's components, such as the ring structure and driving devices, which adjust the posture to keep the sensor accessible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sensor is disposed on the spherical housing, then the device can receive touch inputs, but the sensor becomes difficult to access due to rolling movements
Solution Approach 1:
The patent applies the dynamics principle by making the sensor position adjustable through a rotation mechanism. The sensor can be rotated to different positions on the spherical housing, allowing it to be dynamically repositioned to an accessible location for user interaction while maintaining its functional stability during device movement.
Solution Approach 2:
The patent segments the sensor assembly from the main spherical housing by introducing a separate rotation mechanism. This segmentation allows the sensor to be independently positioned and adjusted relative to the housing, resolving the contradiction between maintaining sensor stability and ensuring accessibility during rolling movements.
2Productivity
If the spherical housing rolls to move the device, then the device can be propelled, but the sensor position becomes unstable and difficult to access
Solution Approach 1:
The rotation mechanism enables dynamic adjustment of the sensor position independent of the spherical housing's rolling motion. This allows the sensor to be positioned optimally for user access while the housing continues to roll for device propulsion, resolving the conflict between mobility and accessibility.
Solution Approach 2:
The rotation mechanism acts as an intermediary between the spherical housing and the sensor. It decouples the sensor's positional stability from the housing's rolling motion, allowing the sensor to maintain a stable, accessible position while the housing moves freely for propulsion.
