Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a non-contact interface is used, then the need for frequent cleaning is reduced and infection risks are lowered, but the interface becomes unintuitive and lacks effective prompts leading to poor user experience
Solution Approach 1:
The patent introduces floating images as an intermediary visual element between the user and the interface. These images serve as intuitive prompts and feedback mechanisms that mediate the interaction, making the non-contact interface as user-friendly as contact interfaces while maintaining the hygiene benefits of non-contact interaction.
Solution Approach 2:
The system provides real-time visual feedback through floating images that respond to user actions. When users interact with the interface, floating images appear to indicate the system's response, creating an intuitive feedback loop that improves user experience without requiring physical contact with the device surface.
2Ease of operation
If a contact interface is used, then the user experience is intuitive and effective prompts are provided, but frequent cleaning is required to prevent contamination and infection
Solution Approach 1:
The patent replaces the mechanical contact-based interaction system with an optical/non-contact system. Instead of requiring physical touch to activate interface elements, the system uses floating images that can be interacted with through non-contact means, eliminating the need for frequent cleaning while maintaining intuitive operation.
3Object-affected harmful factors
If a non-contact interface is used, then body fluids are prevented from remaining on the device surface, but the interface lacks intuitive control and effective prompts
Solution Approach 1:
The floating images utilize visual changes including color variations to provide feedback to users. Different colors or color changes in the floating images indicate different states or responses, ensuring that the non-contact interface provides rich visual information and intuitive control cues without requiring physical contact.

AI summary
A device and a method for generating floating images are provided. An optical imaging module generates a first floating image. A sensing module sends a detection signal to sense first position information of a tested object at a first time point, and generates a feedback signal according to the first position information when the first position information is within a contour range of the first floating image. A signal processing module is electrically connected to the optical imaging module and the sensing module to receive the feedback signal and generate at least one control command and/or at least one feedback command corresponding to the feedback signal. The at least one control command is transmitted to a controller to perform corresponding control on the controller, and the at least one feedback command is transmitted to the optical imaging module, so that the optical imaging module generates a second floating image different from the first floating image.
