Bent Sensor Clip for Flask Medium Replacement Without Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-sensor components require removal of the sensor unit from the container during culture medium replacement, disrupting the measurement process.
Innovation Solution
A sensor attachment member with a mounting portion, bent portion, and wiring portion that allows the sensor to be attached to the container opening while maintaining access, enabling tasks like medium replacement without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sensor unit is held inside the container with a housing portion inserted into the accommodation opening, then the sensor can be positioned for measurement, but the housing must be removed to perform culture medium replacement, interrupting the measurement process
Solution Approach 1:
The sensor attachment member is divided into a mounting portion that holds the sensor and a bent portion that attaches to the container opening. This segmentation allows the sensor to remain attached via the bent portion while the mounting portion can be accessed for medium replacement operations.
Solution Approach 2:
The bent portion acts as an intermediary element that connects the sensor attachment member to the container opening. It enables the sensor to remain fixed at the opening while allowing access to the container interior for culture medium replacement without removing the entire sensor unit.
2Ease of operation
If the sensor unit is removed from the container opening to perform maintenance tasks, then access to the container interior is achieved, but the measurement process must be interrupted and the sensor must be reattached
Solution Approach 1:
The attachment structure is segmented into a mounting portion for sensor holding and a bent portion for opening attachment. This allows the bent portion to remain in place during maintenance tasks while the mounting portion allows access to the container interior.
Solution Approach 2:
The bent portion is designed to be flexible enough to allow access movements while maintaining attachment to the opening. This dynamic structure enables maintenance operations without complete removal of the sensor unit, maintaining measurement continuity.
3Reliability
If the housing portion is inserted into the accommodation opening to hold the sensor, then the sensor is secured for measurement, but the entire housing must be removed to open the accommodation opening for medium replacement
Solution Approach 1:
The attachment member is segmented into a mounting portion and a bent portion. The bent portion attaches to the opening while the mounting portion holds the sensor, simplifying the overall structure compared to a complete housing while maintaining sensor positioning stability.
Solution Approach 2:
The bent portion is designed as a flexible element that can be attached to the container opening and maintains sensor positioning while allowing access operations. This flexible structure reduces complexity compared to rigid housing portions.

AI summary
A sensor clip (10) is a member that attaches a sensor (20) used in a state of having been inserted into a flask (40) to an opening (42), and includes a mounting portion (11) and a bent portion (13). The sensor (20) has an end portion (22) including an electrode (22a), an end portion (23) including a contact (23a), a main body portion (21) that couples the end portions (22, 23), and a wiring portion (24) that is provided to the main body portion (21) and connects the electrode (22a) to the contact (23a). The main body portion (21) of the sensor (20) is mounted on the mounting portion (11). The bent portion (13) is coupled to the mounting portion (11) and is bent along the outer peripheral surface from the inner peripheral surface of the opening (42) and thereby latched to the opening (42) of the flask (40).
