Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure detection devices experience variations in pressure detection characteristics due to inconsistent force applied when mounting and removing flow passage units, leading to inefficiencies and potential safety issues during fluid changes.
Innovation Solution
A pressure detection device with a mounting unit that uses an urging force to consistently contact the pressure detecting surface with the pressure transmitting surface, allowing for easy and secure mounting and removal of flow passage units through a rotatable mechanism with a protrusion and groove system, and a sensing unit to confirm proper alignment and securement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the internal thread of the nut is screwed onto the external thread of the flow passage unit to mount the pressure detecting surface with the pressure transmitting surface, then the flow passage unit can be removably mounted on the pressure detection unit, but the strength of force to cause contact between the surfaces depends on the operator's force and varies, leading to variation in pressure detection characteristics
Solution Approach 1:
The mounting unit automatically generates the urging force needed to press the pressure detecting surface against the pressure transmitting surface through its own elastic deformation, eliminating dependence on operator force. The mounting unit itself serves to provide the consistent contact force without requiring external manual adjustment.
Solution Approach 2:
The mounting unit utilizes elastic deformation as a variable parameter to generate and regulate the urging force. By changing its physical state through elastic deformation, the mounting unit maintains consistent contact pressure between the pressure detecting surface and pressure transmitting surface regardless of operator input variations.
2Adaptability or versatility
If the flow passage unit is replaced to change the fluid being passed through, then a new flow passage unit can be mounted on the pressure detection unit, but extensive cleaning work is required and time is consumed
Solution Approach 1:
The pressure detection device is divided into separable components: the pressure detection unit and the flow passage unit. This segmentation allows the flow passage unit to be easily removed and replaced without affecting the pressure detection unit, enabling quick fluid changes without extensive cleaning requirements.
Solution Approach 2:
The flow passage unit is designed as a disposable or easily replaceable component. When the fluid being passed through needs to be changed, the flow passage unit can be quickly removed and replaced with a new one, eliminating the need for extensive cleaning and time consumption associated with cleaning and sanitizing the same component repeatedly.
3Measurement precision
If the mounting unit uses elastic deformation to generate urging force, then consistent contact force is achieved between the pressure detecting surface and pressure transmitting surface, but the mounting unit requires precise positioning and alignment
Solution Approach 1:
The mounting unit incorporates asymmetric features such as a protrusion and a groove with specific geometric configurations. These asymmetric elements guide the alignment process and ensure proper positioning of the pressure detecting surface relative to the pressure transmitting surface, simplifying the positioning requirement through inherent geometric constraints.
Solution Approach 2:
The mounting unit acts as an intermediary component between the pressure detecting surface and the pressure transmitting surface. It mediates the interaction by providing a consistent elastic urging force while incorporating alignment features (protrusion and groove) that simplify the positioning process, thus reducing the complexity of precise alignment requirements.

AI summary
Provided is a pressure detection device including: a pressure detection unit configured to detect a pressure transmitted to a pressure detecting surface; a flow passage unit in which a pressure transmitting surface for transmitting a pressure of a fluid to the pressure detecting surface is formed; and a mounting unit for removably mounting the flow passage unit on the pressure detection unit. The pressure detection unit has a sensor unit having the pressure detecting surface, a holding unit configured to hold the sensor unit to be movable along an axis orthogonal to the pressure detecting surface, and a urging unit configured to generate urging force to urge the sensor unit toward the pressure transmitting surface. The mounting unit mounts the flow passage unit on the pressure detection unit with the pressure detecting surface being in contact with the pressure transmitting surface under urging force generated by the urging unit.
