Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If acoustic wave touch screen technology is used to provide contactless interaction, then ease of operation is improved, but reliability deteriorates due to delayed terminal response causing multiple touches and misoperations
Solution Approach 1:
The patent introduces an airflow generating module that provides immediate tactile feedback to the user when a touch is detected. The controller activates the airflow module to blow air through the guard plate toward the user's finger, creating a perceptible airflow sensation that confirms successful touch detection. This feedback mechanism resolves the reliability issue by giving users immediate confirmation of their input, preventing misoperations caused by delayed terminal responses.
2Reliability
If multiple successive touches are performed due to delayed response, then user attempts to ensure successful input increase, but harmful factors increase due to terminal misoperation
Solution Approach 1:
The airflow generating module provides immediate tactile feedback upon detecting a touch, confirming successful input detection before the user performs additional touches. This feedback loop prevents the harmful effect of misoperations by ensuring users receive confirmation of their input's successful registration.
Solution Approach 2:
The system provides preemptive feedback through airflow generation that cushions against potential misoperations. By giving users immediate tactile confirmation of successful touch detection, the system prevents the chain of events that would lead to multiple successive touches and potential misoperations.
3Reliability
If airflow generating module is added to provide tactile feedback, then reliability of touch detection is improved, but device complexity increases
Solution Approach 1:
The patent introduces an airflow generating module as an intermediary component between the touch detection system and the user. This mediator translates the digital touch detection into a physical tactile sensation (airflow) that the user can perceive, providing reliable feedback without requiring complex changes to the core touch detection architecture. The airflow module acts as a bridge between the electronic detection system and human sensory perception.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents multiple touches by providing tactile confirmation of successful interaction, enhancing user experience and reducing misoperations by ensuring immediate recognition of touch inputs.
Implementation Method 1
The acoustic wave generator is capable of transmitting a high frequency acoustic wave across the screen surface. When a finger touches the screen, the acoustic wave at the touch point is blocked. The coordinate position of the touch point can be determined by detecting the position to which the change in the acoustic wave corresponds.
Implementation Method 2
controlling all or part of the at least one airflow generation modules to generate airflow that blows to a user's finger via the through hole of the guard plate when it is detected that the user's finger touches the guard plate
