Rotatable Circuit Housing for Sensor Probe Display Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement apparatuses face challenges in allowing the display direction to be selected independently of the sensor probe's orientation, leading to potential misalignment and user inconvenience.
Innovation Solution
A measurement apparatus design featuring a sensor probe and a circuit housing where the circuit housing is fixable at multiple rotation positions relative to the sensor probe, enabling the display direction to be chosen regardless of the sensor probe's orientation, with connectors that can absorb misalignment and a configuration allowing the display to be positioned orthogonally to the insertion direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is fixed in a single orientation relative to the sensor probe, then the structure is simple, but the display direction cannot be adjusted independently of the sensor probe orientation
Solution Approach 1:
The circuit housing is designed to be rotatable relative to the sensor probe about the insertion direction axis, transforming a static fixed-orientation structure into a dynamic adjustable one. This allows the display direction to be changed independently while maintaining a relatively simple overall structure.
Solution Approach 2:
The measurement apparatus is divided into separable components (sensor probe and circuit housing) that can be connected in multiple rotational positions. This segmentation enables independent orientation adjustment of each component while keeping the connection structure simple.
2Ease of operation
If the display direction is coupled with the sensor probe orientation, then the structure is simple, but the display may not align with the desired viewing direction
Solution Approach 1:
The rotatable connection between circuit housing and sensor probe provides dynamic adjustability, allowing the display to be aligned with the desired viewing direction while maintaining a simple connection structure that requires no additional alignment mechanisms.
Solution Approach 2:
The connection structure serves multiple functions: it provides both mechanical support and rotational adjustability. This multi-functionality eliminates the need for separate alignment mechanisms, keeping the overall structure simple while achieving easy display alignment.
3Adaptability or versatility
If the circuit housing is fixed in a single position, then the manufacturing is simple, but the display cannot be positioned orthogonally to the insertion direction
Solution Approach 1:
The design provides positional flexibility through rotation after manufacturing, rather than requiring multiple pre-configured manufacturing variants. The circuit housing can be manufactured in a standard configuration and then adjusted to different positions (including orthogonal positioning) through rotation during installation.
Solution Approach 2:
The connection structure is pre-designed with rotational capability built-in, allowing the display to be positioned orthogonally or at other angles without requiring complex manufacturing processes. The rotational mechanism is prepared in advance, enabling flexible positioning during installation.

AI summary
A measurement apparatus includes a sensor probe and a circuit housing. The sensor probe is insertable through an opening provided in a flow path wall of a flow path through which a fluid to be measured flows and is used in a predetermined orientation relative to the flow direction of the fluid to be measured. The circuit housing includes a display, disposed outside of the flow path, and connects to the sensor probe. The circuit housing is fixable at a plurality of rotation positions relative to the sensor probe about an axis along the insertion direction of the sensor probe. The measurement apparatus allows the display direction of the display to be selected regardless of the orientation of the sensor probe.
