Innovation Solution
A sensor holder with a cylindrical housing and conical design, featuring a joint for easy movement between measurement and maintenance positions, a fastening unit, and a sealing element to prevent air bubbles, allowing for efficient cleaning and maintenance without altering the liquid volume or measurement signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the flow vessel is designed with a cleaning nozzle for automatic cleaning, then cleaning capability is improved, but air bubbles accumulate in the flow vessel interfering with measurement
Solution Approach 1:
The flow vessel is segmented into a measurement region and a cleaning region. The conical housing design creates a geometric separation where cleaning flushing can be applied without allowing air bubbles to accumulate in the measurement path. The cone angle is specifically designed to guide air bubbles away from the sensor measurement zone.
Solution Approach 2:
A buffer element is introduced as an intermediary component between the cleaning mechanism and the measurement region. This buffer prevents direct communication between the cleaning flushing and the measurement path, allowing cleaning to occur while preventing air bubbles from entering the measurement zone.
2Ease of repair
If the sensor holder allows easy disassembly for maintenance, then ease of maintenance is improved, but structural stability and sealing may be compromised
Solution Approach 1:
The sensor holder is divided into separable components including a removable sensor carrier and a stationary housing. The sensor carrier can be easily detached for maintenance while the housing remains in place, maintaining structural stability. Quick-release fastening elements enable tool-free disassembly and reassembly.
Solution Approach 2:
Maintenance-related components such as the sensor carrier and sealing elements are pre-configured for quick release. The design includes pre-positioned sealing elements and fastening mechanisms that are already in place, allowing maintenance personnel to perform maintenance without needing to assemble or disassemble complex structures.
3Volume of moving object
If the housing volume is minimized to fit restricted space conditions, then space utilization is improved, but the liquid volume may be insufficient for accurate measurement
Solution Approach 1:
The flow vessel transitions from a traditional cylindrical shape to a conical shape. This geometric transformation allows the measurement region to be extended in the axial dimension while reducing the radial dimension. The cone angle is optimized to provide sufficient liquid volume for accurate measurement while minimizing the overall housing volume to fit restricted installation spaces.
4Ease of repair
If the flow vessel is designed for easy sensor exchange, then ease of maintenance is improved, but the structural complexity increases
Solution Approach 1:
The sensor holder employs a modular design with a separate sensor carrier that can be independently removed and replaced. The sensor carrier includes integrated fastening elements and sealing components, allowing the sensor to be exchanged as a complete unit without disturbing the housing or other components.
Solution Approach 2:
The fastening system incorporates dynamic elements such as spring-loaded latches or bayonet connectors that automatically engage and disengage. These mechanisms provide secure mounting during operation but allow quick release during maintenance, achieving easy sensor exchange without requiring complex manual assembly procedures.

AI summary
The present disclosure discloses a sensor holder for a flow sensor, comprising a substantially cylindrical housing with a housing interior with an opening at a first front face. The opening is designed to receive the flow sensor. The housing at the second front face, which is opposite the first front face, is conical. A first flushing opens to the housing interior, where the opening opens into the end region of the cone, and a second flushing opens to the housing interior. A fastening unit is designed to fasten the flow sensor in the housing, and a first wall holder is designed to be fastened to a wall. The first wall holder comprises a joint in the region of the second front face, with the joint connecting to the housing. The housing can be moved via the joint from a measurement position into a maintenance position.
