Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronics housings are inflexible and require a new housing when electronics need to be changed, limiting adaptability and requiring complex reconfiguration for different devices.
Innovation Solution
The electronics housing features perpendicular side walls with multiple fasteners for accommodating circuit boards in various orientations, allowing for flexible positioning and connection of multiple boards, and includes a support rail bus connector for automatic electrical connections, enabling easy device replacement and expansion without disrupting signal flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional housings are used with fixed terminal positions, then the housing structure is simple, but the adaptability to different devices is limited
Solution Approach 1:
The housing is designed with a standardized support rail interface that can accommodate multiple types of electronic devices and configurations. The upper part can be detached and replaced to adapt to different devices, while the base part remains universal. This allows one housing structure to serve multiple functions and adapt to various devices without requiring complete redesign.
Solution Approach 2:
The housing is divided into a base part and an upper part that can be separated. The base part contains the support rail interface and remains fixed, while the upper part containing the terminals can be detached and replaced. This segmentation allows the terminal positions to be adapted to different devices by changing the upper part, while maintaining a simple universal base structure.
2Ease of operation
If housings are firmly locked to the support rail, then the mechanical stability is high, but the ease of removal and reconfiguration is reduced
Solution Approach 1:
The locking element is designed to be dynamically controllable - it can be in a locked state during normal operation to ensure mechanical stability, and can be easily released when removal is needed. The spring-loaded design provides automatic locking upon insertion while allowing simple release through manual actuation, enabling the system to switch between stable and removable states as needed.
3Ease of operation
If spring-loaded locking elements are used for secure mounting, then the mechanical connection is reliable, but the force required for removal increases
Solution Approach 1:
The locking element is designed to be extractable or retractable through a simple actuation mechanism. Instead of requiring significant force to overcome the spring load directly, the design allows the locking element to be released through a lever or cam mechanism that converts small input force into the necessary retrieval motion, reducing the force required for removal.
4Productivity
If manual wiring connections are used between housings, then the connection flexibility is high, but the time required for configuration and assembly increases
Solution Approach 1:
Multiple individual wiring connections between neighboring housings are merged into a single bus bar system. The bus bar provides a common electrical connection that automatically connects multiple devices when they are mounted on the support rail, eliminating the need for individual wiring between each housing and reducing assembly time while maintaining connection flexibility.

AI summary
An electronics housing for placement on a support rail includes a base part and an upper part. The base part and the upper part can be detachably connected to one another, and the base part can be snapped to the support rail. Two housing side walls having fasteners are disposed opposite to each other and are disposed parallel to each other. The housing side walls are also disposed perpendicular to the support rail. A circuit board is disposed parallel to the support rail using the fasteners. At least two connection terminals or plug-in connectors are provided for connecting the electrical conductors. The connection terminals are electrically connectable to the circuit board.
