Solution Overview
Problem
Existing electrical/electronic installation devices for building systems often fail to determine room temperature quickly and precisely, which hinders the efficient activation of heating and cooling systems.
Innovation Solution
The device employs a modular design with a first and second sensor element for temperature detection, allowing for the consideration of thermal influences from the insert, eliminating the need for a separate temperature sensor to calculate its thermal impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single temperature sensor is used in existing installation devices, then the device structure remains simple, but the room temperature cannot be determined quickly and precisely enough
Solution Approach 1:
The temperature measurement function is segmented into two separate sensor elements: a first sensor element for detecting room temperature and a second sensor element for detecting thermal influence of the insert. This segmentation allows simultaneous measurement of both parameters, enabling precise room temperature determination while accounting for thermal interference, thus resolving the contradiction between measurement precision and time consumption.
Solution Approach 2:
The second sensor element acts as an intermediary that specifically measures the thermal influence of the insert. By introducing this intermediate measurement, the system can compensate for thermal interference and achieve accurate room temperature readings without requiring additional time for separate calibration or measurement steps.
2Measurement precision
If multiple sensor elements are used to improve temperature measurement accuracy, then measurement precision improves, but device complexity increases
Solution Approach 1:
Both sensor elements are integrated into the same installation device with a unified evaluation unit that processes signals from both sensors. The evaluation unit implements a standardized calculation method that works universally with different insert types and sensor configurations, reducing overall system complexity despite the presence of multiple sensors.
Solution Approach 2:
The system changes from measuring a single temperature parameter to measuring two distinct temperature parameters (room temperature and insert thermal influence). By introducing this parameter differentiation, the system achieves higher measurement precision while maintaining manageable complexity through systematic parameter separation and processing.
3Measurement precision
If thermal influence of the insert is not compensated, then the device structure remains simple, but temperature determination accuracy deteriorates
Solution Approach 1:
The evaluation unit continuously receives temperature signals from both sensor elements and dynamically calculates compensated room temperature values. This feedback mechanism automatically adjusts measurements based on real-time thermal influence data, achieving high measurement accuracy without requiring complex manual calibration or adjustment mechanisms.
Solution Approach 2:
The system uses its own second sensor element to measure and compensate for its own thermal influence. This self-service approach allows the installation device to automatically correct for its own thermal interference, achieving high measurement accuracy without requiring external calibration equipment or complex external compensation systems.

AI summary
An electrical/electronic installation device is proposed, comprising a first functional module designed as an insert, which is to be housed in an installation box. This first functional module is provided on the rear with connecting elements for connection to a building's installation system and on the front with a connector for connecting a second functional module designed as an attachment, which is to be arranged on the wall side via an intermediate design frame. The attachment is provided with a front panel on the user side, and at least one circuit board is arranged in the housing of the attachment.For the purpose of creating an electrical/electronic installation device that determines the prevailing temperature in the room as quickly and accurately as possible, in order to enable demand-based control of connected heating systems, such as fan coil units, underfloor heating, radiator heating and/or air conditioning systems, in a particularly simple manner, at least one first sensor element is arranged on the top side of the circuit board facing the front panel for temperature measurement, which is attached to the underside of the front panel of the attachment, and the underside of the circuit board facing away from the front panel is equipped with at least one second sensor element, also intended for temperature measurement.
