Room Temperature Regulator Sensor Dome for Flush Wall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing room temperature controllers for wall-mounted standardized device boxes are aesthetically unappealing due to protrusions from the wall for air inlets, which compromise the appearance of the room while requiring a large installation space for power supply and safety considerations.
Innovation Solution
A room temperature controller design featuring a dome-like sensor protruding from the front of the housing, with the temperature sensor thermally connected to the exposed sensor dome front wall, eliminating side air inlets and allowing for precise temperature detection while maintaining a flat profile, using an electrically insulating plastic housing and a removable cover panel without visible screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If side air inlets are provided in the cover panel and electronics housing to enable high room air volume flow, then temperature detection precision is improved, but the device protrudes far from the wall impairing appearance
Solution Approach 1:
The air inlet function is extracted from the side surfaces and relocated to the front sensor dome area. The sensor dome itself serves as the air inlet structure, allowing air to flow directly to the temperature sensor without requiring side protrusions, thus resolving the contradiction between measurement precision and aesthetic appearance.
Solution Approach 2:
The air inlet approach is changed from lateral (side) direction to frontal direction through the sensor dome. This dimensional change allows the device to maintain a flush wall mounting appearance while still enabling adequate air flow for accurate temperature sensing through the front-facing sensor dome structure.
2Object-affected harmful factors
If the temperature sensor is placed inside the electronics housing for safety, then operator safety is improved, but temperature detection accuracy deteriorates due to limited air access
Solution Approach 1:
The sensor dome acts as an intermediary structure between the external environment and the temperature sensor. It provides a protected pathway for air to reach the sensor while keeping the sensor itself enclosed within the housing for safety, thus resolving the contradiction between safety and measurement accuracy.
Solution Approach 2:
The temperature sensor is nested within the electronics housing for safety, while the sensor dome is nested within the cover panel and protrudes slightly to provide air access. This nested arrangement allows the sensor to be protected from direct external contact while still being accessible to room air through the dome structure.
3Adaptability or versatility
If the electronics assembly is designed to be compact for standardized device box mounting, then installation versatility is improved, but space for adequate air inlets and safety clearance is reduced
Solution Approach 1:
The sensor dome is merged with the electronics housing as an integrated structure, eliminating the need for separate air inlet components. This merging allows the compact electronics assembly to maintain adequate air access volume within the constrained space of standardized device boxes while preserving safety clearances.

Implementation Method 1
the temperature sensor of the room temperature controller is arranged in the sensor dome and is thermally connected to the sensor dome front wall that is exposed to flow
Implementation Method 2
the cover panel has a sensor dome opening corresponding to the sensor dome, into which the sensor dome is immersed when the room temperature controller is mounted, so that at least one sensor dome front wall is directly exposed to the room air
