Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current two-part housing designs for building control systems often make it difficult to replace electronic circuits without damaging the components and can lead to loose connections, complicating maintenance and upgrades.
Innovation Solution
A housing design featuring a first part with an extractable handle and guide for easy removal and reconnection, along with exchangeable plates and hooks for secure locking, allowing for simple and efficient replacement of electronic circuits without affecting wiring or cabling, and enabling customization through interchangeable plates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a two-part housing design is used to allow separate manufacturing and modular assembly, then manufacturing flexibility and adaptability are improved, but the connection between housing parts becomes too loose leading to unwanted disconnection
Solution Approach 1:
The housing is divided into two separate parts that can be manufactured independently and assembled modularly. The first housing part contains the electronic circuit while the second housing part contains terminal blocks with wiring. This segmentation allows flexible manufacturing and assembly while maintaining reliable connection through the coupling mechanism.
Solution Approach 2:
A coupling mechanism acts as an intermediary between the two housing parts to ensure secure connection. The coupling prevents the housing parts from disconnecting during operation while allowing for intentional separation when needed for maintenance or replacement.
2Adaptability or versatility
If existing two-part housing designs are used for easy assembly, then manufacturing adaptability is improved, but replacement of electronic circuits becomes difficult and may damage components
Solution Approach 1:
The housing is segmented into a first part containing the electronic circuit and a second part containing the wiring infrastructure. This segmentation allows the electronic circuit to be replaced by removing only the first housing part while leaving the wired second part in place, facilitating easy repair without damaging components.
Solution Approach 2:
The coupling mechanism serves as an intermediary that enables easy separation of the first housing part from the second part. This allows rapid replacement of electronic circuits while maintaining the integrity of the overall system and preventing damage to wiring or terminal blocks.
3Strength
If the handle is permanently fixed to the housing, then structural strength is improved, but the handle may be damaged during frequent opening operations
Solution Approach 1:
The handle is designed with movable attachment to the first housing part, allowing it to be extracted when not in use. This dynamic configuration protects the handle from damage during frequent opening operations while maintaining sufficient attachment strength during operation. The handle can be inserted and removed as needed.

AI summary
A housing (3) for an electronic circuit intended for a building control system is disclosed. The housing (3) comprises a first housing part (1) comprising the electronic circuit intended for the building control system, and a second housing part (2) that is connected to the first housing part (1). Furthermore, a handle (4; 5) is movably attached to and extractable from the first housing part (1) for providing a grip when the handle is extracted from the first housing part (1) and thereby allowing, by pulling the handle (4; 5), the first housing part (1) to be removed from the second housing part (2).
