Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing CPAP devices face challenges in aligning the first unit's blower with the second unit's channel and terminal, making the attachment process time-consuming and prone to positional deviations.
Innovation Solution
The CPAP device design includes a first unit with a built-in blower and a second unit with channels for air circulation, featuring a cylindrical circulation portion with a connection portion and conductive terminals for easier alignment and attachment, reducing positional deviations between the units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the first unit is attached to the second unit with separate channels and terminals, then functional integration is achieved, but alignment difficulty increases and attachment time is extended
Solution Approach 1:
The patent combines the channel and terminal into a single integrated connection structure. The second unit is equipped with a connection portion that simultaneously provides both channel connection and terminal connection functions, eliminating the need for separate alignment of channel and terminal between units.
Solution Approach 2:
The connection portion acts as an intermediary structure that simplifies the attachment process. By providing a unified connection interface that encompasses both channel and terminal connection capabilities, it mediates the complex alignment requirement into a single straightforward connection action.
2Reliability
If separate channel and terminal alignment is required, then functional completeness is ensured, but attachment precision decreases
Solution Approach 1:
The connection portion merges channel connection and terminal connection into a single integrated structure. This ensures that both functional requirements (channel alignment and terminal alignment) are met simultaneously through one connection action, maintaining functional completeness while improving alignment precision.
3Reliability
If multiple alignment points are provided, then functional reliability is improved, but attachment complexity increases
Solution Approach 1:
The patent merges multiple alignment functions (channel alignment and terminal alignment) into a single connection portion structure. This integration maintains the reliability benefits of multiple alignment points while eliminating the complexity of managing separate alignment procedures for each point.

AI summary
The present disclosure relates to a continuous positive airway pressure (CPAP) device which sends, into an airway of a user, air sucked into the device. A body unit as a first unit has a cylindrical first lead-out portion through which air circulates. A base unit as a second unit has a third introduction portion to which the first lead-out portion is to be connected. A body-side terminal is provided as a first terminal with conductivity at the first lead-out portion of the body unit. A base-side terminal is provided as a second terminal with conductivity at the third introduction portion of the base unit. The body-side terminal is in contact with the base-side terminal while the body unit is attached to the base unit.
