Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for securing airtightness in dissolved-gas monitor devices installed on existing pipes are costly due to high machining accuracy requirements, making it challenging to maintain airtightness with a simple configuration.
Innovation Solution
A clamp with a pair of pipe pressing portions that sandwich the pipe, featuring a gas storage portion and an exhaust port, where the re-permeable membrane covers the opening to ensure airtightness and prevent foreign substances, and support portions to maintain the pipe's shape, allowing for secure gas concentration measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are used to sandwich the pipe from the outside to form a sealed space, then the device can be installed on existing pipes, but high machining accuracy is required to secure airtightness, increasing manufacturing cost
Solution Approach 1:
The patent employs flexible sealing members (gaskets or O-rings) made of elastomeric materials that conform to the pipe surface irregularities. These flexible sealing elements are positioned between the clamp components and the pipe, allowing the rigid clamp structure to maintain its simple geometry while the flexible seal adapts to surface variations, eliminating the need for high machining accuracy on the clamp's bonded surfaces.
2Reliability
If high machining accuracy is applied to secure airtightness, then the sealed space maintains reliability, but the manufacturing cost of components increases
Solution Approach 1:
The flexible sealing members compensate for minor dimensional variations and surface irregularities, maintaining reliable airtightness without requiring expensive high-precision machining of the clamp components. This approach significantly reduces manufacturing costs while preserving the integrity of the sealed space.
Solution Approach 2:
The flexible sealing member acts as an intermediary element between the rigid clamp components and the pipe surface. It mediates the interface where sealing is required, absorbing dimensional tolerances and surface irregularities, thereby allowing the clamp components to be manufactured with standard tolerances rather than high precision.
3Device complexity
If the gas storage portion is opened to the side of the pipe for simple configuration, then the structure is simplified, but airtightness must be maintained at the opening
Solution Approach 1:
The opening of the gas storage portion is sealed with a flexible membrane or diaphragm that allows for gas permeation while maintaining airtightness. This flexible sealing approach simplifies the overall configuration by eliminating complex mechanical sealing mechanisms, while still ensuring reliable containment of the stored gas through the adaptive sealing properties of the flexible material.

Function Achieved in This Case
The clamp effectively secures airtightness with a simple configuration, prevents foreign substance contamination, and maintains accurate gas concentration measurement by ensuring the gas permeates only through the designated path, reducing leakage and maintaining a constant measurement environment.
Implementation Method 1
measures the concentration of gas dissolved in an aqueous solution of the gas circulating through the inside of a pipe which allows the permeation of a specific gas
Implementation Method 2
the re-permeable membrane covers the opening to ensure airtightness and prevent foreign substances, and support portions to maintain the pipe's shape

AI summary
Provided is a clamp for dissolved-gas monitor capable of securing the airtightness of a sealed space for storing gas permeating through a pipe with a simple configuration. A clamp for dissolved-gas monitor according to this invention includes a pair of pipe pressing portions which sandwiches a pipe and a fixing portion which detachably fixes the pair of pipe pressing portions such that the pair of pipe pressing portions sandwiches the pipe. One of the pair of pipe pressing portions has a gas storage portion which is a space which is opened to the side of the pipe and stores the gas permeating through the pipe and an exhaust port which exhausts the gas stored in the gas storage portion.
