Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional oral body devices face challenges in easily attaching and detaching oral appliances without saliva contamination, as the detachable portions often come into contact with the oral cavity, leading to saliva adherence during removal.

Innovation Solution

An oral body device with an attachment/detachment operation unit that applies and releases force to an oral appliance with an electrical connection portion, allowing for easy attachment and detachment while maintaining electrical connection, using a pressing member that slides obliquely to secure and release the appliance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the oral appliance is directly removed from the oral cavity, then the detachment operation is simple, but saliva adheres to the detachable portion during removal

Engineering Contradiction:

Improvedetachment operationVSAvoidsaliva contamination

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The device is divided into two main segments: the oral appliance that contacts the oral cavity and the body device that remains outside. The oral appliance can be detached from the body device, allowing the user to remove only the contaminated oral appliance while leaving the body device clean and in place.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attachment/detachment operation unit acts as an intermediary mechanism between the oral appliance and body device. It provides a controlled interface for attachment and detachment operations, enabling easy separation of the oral appliance from the body device without direct manual manipulation of the oral appliance itself.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the oral appliance is made detachable for easy removal, then detachment is simplified, but electrical connection reliability deteriorates

Engineering Contradiction:

Improveattachment and detachmentVSAvoidelectrical connection

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The attachment/detachment operation unit combines multiple functions into a single integrated mechanism: it simultaneously establishes both the mechanical connection (for structural support) and the electrical connection (for signal transmission). This unified approach ensures that both connections are made or broken together, maintaining reliability while enabling easy detachment.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The attachment/detachment operation unit serves multiple purposes: it provides mechanical attachment, electrical connection, and a controlled interface for both attachment and detachment operations. This multi-functional design allows the system to maintain reliable electrical connections while enabling simple user operations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An oral body device is provided for attaching to and detaching from an oral appliance that has an electrical connection portion. The device includes a body, and an attachment/detachment operation unit that has an electrical connection conductor and is configured to detachably attach the oral appliance to the body portion by operating application and release of force to the oral appliance. Moreover, the attachment/detachment operation unit fixedly attaches the oral appliance in a state in which the electrical connection portion is electrically connected to the electrical connection conductor by applying a force to the oral appliance, and releases the fixation by releasing the force applied to the oral appliance to detach the oral appliance.
