Multi-Sensor Assembly Nested Design for Space-Constrained Signal Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-sensor assemblies require significant space for installation and face challenges in accurately transmitting measured physical quantities to controllers, especially in confined environments, as they often need multiple sensors and suffer from interference between sensing and control environments.
Innovation Solution
A multi-sensor assembly with a housing containing a first sensor and at least one second sensor, where the second sensor is integrated within the first sensor, and a connector system that allows simultaneous measurement and transmission of physical quantities through a tubular housing with a coupling ring for secure signal transmission, minimizing space requirements and impedance changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors are used to measure multiple physical quantities, then measurement capability is improved, but installation space requirement increases
Solution Approach 1:
The patent implements nesting by placing the second sensor inside the first sensor's mounting groove structure. The first sensor serves as a housing for both itself and the second sensor, allowing multiple sensors to occupy a compact integrated space rather than requiring separate installation areas for each sensor.
Solution Approach 2:
The patent merges multiple sensors and their connection lines into a single integrated assembly. The first sensor, second sensor, first connection line, and second connection line are combined within one housing structure, enabling multiple measurement functions to be achieved in a unified compact unit.
2Area of stationary object
If sensors are installed in confined spaces, then space efficiency is improved, but signal transmission accuracy deteriorates due to environmental interference
Solution Approach 1:
The patent uses the housing structure as an intermediary barrier that isolates the sensors from external environmental interference while allowing controlled signal transmission. The housing acts as a protective mediator that maintains signal integrity by preventing external disturbances from affecting the sensors and controller in confined installation spaces.
Solution Approach 2:
The patent segments the signal transmission path into distinct isolated channels. The first connection line and second connection line are separately routed through the housing structure, with the second connection line passing through the first connector member. This segmentation prevents electromagnetic interference between different signal paths while maintaining transmission accuracy.
3Ease of operation
If connection lines are routed through sensor assemblies, then ease of installation is improved, but signal integrity deteriorates due to impedance changes
Solution Approach 1:
The patent introduces the housing and connector members as intermediary structures that facilitate clean signal transmission. The first connector member and coupling ring act as controlled intermediaries that maintain consistent electrical impedance while allowing connection lines to pass through the assembly, thus preserving signal integrity during installation.
Solution Approach 2:
The patent carefully controls and maintains electrical impedance parameters throughout the signal transmission path. By designing the housing, connector members, and connection lines with consistent material properties and geometric dimensions, the patent minimizes impedance variations that would otherwise degrade signal integrity while allowing flexible installation routing.

AI summary
Proposed is a multi-sensor assembly, and the assembly of the present disclosure includes: a first sensor provided in a sensor coupling unit positioned at a front end of a housing; a second sensor provided in a mounting groove that is open toward a front surface of the first sensor; a first connector member configured to transmit a signal measured by the first sensor and, simultaneously, to firmly fix the first sensor to the sensor coupling unit; and a second connector member screw portion formed on an outer surface of a rear end of the first connector member so as to be coupled to a fixture screw portion of an adjustable fixture provided at a rear end of the housing, thereby moving relatively thereto.
