Head-Mounted Dental Audio-Visual System for Patient Noise Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental treatment environments fail to adequately relax patients and effectively transmit the voice of medical staff due to high-frequency noise and insufficient psychological comfort measures.
Innovation Solution
A system comprising a head-mounted device with an image display unit and ear-mounted speaker, a microphone, voice recognition module, content module, and user interface, which allows patients to select relaxing content and ensures effective voice transmission of medical staff during treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-frequency noise is generated during dental treatment, then dental treatment can be performed effectively, but patient comfort and psychological state deteriorate
Solution Approach 1:
The patent introduces an intermediary system consisting of noise-canceling headphones and audio playback devices that mediate between the dental treatment noise and the patient. The headphones actively cancel high-frequency noise while playing relaxing audio content, serving as a buffer that protects the patient from harmful noise without interfering with the dental treatment process
Solution Approach 2:
The patent converts the harmful high-frequency noise environment into a beneficial relaxing audio experience. By using active noise cancellation technology, the system transforms the noisy dental treatment environment into a calm auditory space where relaxing music or narration can be played, turning the harmful noise into an opportunity for patient relaxation
2Object-affected harmful factors
If traditional LCD monitors are used to provide images to patients, then psychological anxiety can be partially relieved, but voice transmission from medical staff to patient remains ineffective
Solution Approach 1:
The patent makes the audio device multi-functional by combining noise cancellation, relaxing audio playback, and medical staff voice transmission capabilities in a single system. The headphones or earbuds serve multiple purposes: blocking harmful noise, providing relaxation content, and ensuring clear communication of medical instructions, replacing the need for separate LCD monitor and audio communication systems
Solution Approach 2:
The patent replaces the visual LCD monitor system with an audio-based communication system. Instead of displaying images on an LCD screen and relying on acoustic ambient communication, the system uses audio devices to directly transmit both relaxing content and medical staff instructions through the headphones, creating a more effective information transmission channel
3Object-affected harmful factors
If noise protection measures are implemented for patients, then patient comfort improves, but voice communication from medical staff to patient is compromised
Solution Approach 1:
The patent implements feedback mechanisms where the audio system continuously monitors and adjusts audio output based on the dental treatment environment. The system detects when medical staff are speaking and automatically adjusts the mixing of relaxing audio and voice transmission, ensuring that patient protection and communication needs are dynamically balanced through real-time feedback

AI summary
A system for establishing a dental treatment environment, includes: a head-mounted device provided at a dental clinic to be mounted on a patient's head, the head-mounted device having an image display unit and an ear-mounted speaker, a microphone for converting a sound including the voice of the medical staff in charge of the patient into an electric signal; a voice recognition module for recognizing the voice of the medical staff in charge from the electric sound input from the microphone; a content module storing multiple image contents for relaxing the patient mentally physically; a user interface having a content selection unit configured such that the patient can select a play content provided to the image display unit from the multiple image contents; and an output signal generating module for generating an output signal that is output to the head-mounted device.
