Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touchless sensors are not always reliable and can be inadvertently activated, and they typically have a single function, limiting their versatility in operating various components.
Innovation Solution
A touchless sensor system with protuberances defining multiple channels and sensing devices, such as infrared emitters and receivers, and cameras, that detect actions of an object to associate with operational functions of components, allowing for multiple commands and reduced inadvertent triggering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-function touchless sensor is used, then the device simplicity is maintained, but the versatility to operate multiple component functions is limited
Solution Approach 1:
The sensor system is designed to perform multiple functions by detecting different object actions (insertion, removal, rotation) and translating them into different operational commands for components. A single sensor system can activate, deactivate, or adjust component settings based on the detected action type, eliminating the need for multiple separate sensors or switches.
2Reliability
If a simple touchless sensor is used, then the ease of operation is maintained, but the reliability and resistance to inadvertent activation are reduced
Solution Approach 1:
The sensor system divides the detection space into multiple channels (first channel, second channel, third channel) defined by protuberances. Each channel can detect specific types of actions independently, allowing the system to distinguish between intentional user actions and inadvertent movements by analyzing which channels are activated and in what sequence.
Solution Approach 2:
The sensor system requires a sequence of predetermined actions to activate a function. For example, inserting an object into the first channel and then rotating it a specific distance triggers a function, while simply passing an object through without the rotation does not. This preliminary sequencing prevents accidental activation while maintaining ease of use.
