Building controller with adaptable mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Building controllers often require different mounting configurations depending on the installation, either to a wall or a DIN rail, but existing solutions lack adaptability to determine the best mount type in advance.
Innovation Solution
A modular mount system for building controllers that includes a housing with a back plate and sliding mounting clips, allowing configuration between wall and DIN rail mounts using threshold sliding forces to secure the device, with detents to hold positions until sufficient force is applied to change configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a building controller is designed with a fixed mounting method (either wall mount or DIN rail mount), then the mounting structure is simple and reliable, but the adaptability to different installation scenarios is reduced
Solution Approach 1:
The mounting clip is designed to perform multiple functions: it can mount the building controller to either a wall or a DIN rail depending on its position. The clip integrates both wall mounting capability (with securement feature for fasteners) and DIN rail mounting capability (with engagement feature for DIN rail profile) into a single component that can be configured for either application.
Solution Approach 2:
The mounting clip is designed as a movable component that can be slid along the slot between two fixed positions (first position for DIN rail mounting, second position for wall mounting). The detent mechanism allows the clip to be held securely in either position while enabling transition between positions when sufficient force is applied, providing dynamic adaptability.
2Reliability
If a mounting clip is held securely in position using detents, then the mounting stability is improved, but the ease of reconfiguration between mounting types is reduced
Solution Approach 1:
The detent mechanism provides stable holding in each mounting position through mechanical engagement, ensuring reliable mounting during operation. However, the same mechanism allows intentional disengagement when sufficient sliding force is applied, enabling easy reconfiguration between wall and DIN rail mounting types as needed.

AI summary
A building controller may include a housing having a back plate and a mounting clip, which may be slidably disposed relative to the back plate between a wall mount position used when mounting the building controller to the wall, and a DIN rail mount position used when mounting the building controller to a DIN rail. When in the wall mount position, the mounting clip and the back plate may be configured to hold the mounting clip in the wall mount position until at least a first threshold sliding force is applied to the mounting clip. When in the DIN rail mount position, the mounting clip and the back plate are configured to hold the mounting clip in the DIN rail mount position until at least a second threshold sliding force is applied to the mounting clip.
