Modular Power Supply With Segmented Access Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular power supplies lack user-friendly configuration options due to safety concerns, as direct access to the internal components poses electrical hazards and violates certification requirements, leading to secure but inaccessible designs.
Innovation Solution
A modular power supply design featuring a container with a hinged cover and partition that separates the primary input and output portions, allowing safe user access to the output modules while maintaining electrical safety through inaccessible primary input protection, using a flexible printed circuit and cooling openings that prevent direct access to hazardous components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supply container is designed with secure locking mechanisms to prevent unauthorized access, then electrical safety is improved, but user accessibility for configuration deteriorates
Solution Approach 1:
The container is divided into two distinct access zones: a first accessible portion allowing user access to output modules for configuration, and a second inaccessible portion protecting the primary input circuitry. This segmentation enables differentiated access levels that simultaneously improve safety and maintain usability.
Solution Approach 2:
Different portions of the container are assigned different accessibility qualities: the first portion is designed to be accessible to users for module configuration, while the second portion is designed to be inaccessible to protect hazardous components. This local differentiation resolves the contradiction by applying appropriate access restrictions only where needed.
2Ease of operation
If the container is designed to be easily opened by users, then ease of operation is improved, but electrical safety deteriorates due to exposure to primary circuitry
Solution Approach 1:
The container structure is segmented into accessible and inaccessible zones, allowing the accessible portion to be easily opened while the inaccessible portion remains protected. This enables easy user operation without compromising safety.
Solution Approach 2:
A partition wall acts as an intermediary structure that physically separates the accessible first portion from the inaccessible second portion containing the primary input circuitry. This intermediary element prevents direct access to hazardous components while allowing easy access to safe areas.
3Reliability
If vandal-proof threaded connections are used to secure the container, then electrical safety is improved, but device complexity and ease of manufacture deteriorate
Solution Approach 1:
The container closure system is segmented into different connection types: the first portion uses simple snap-fit or removable connections for easy user access, while the second portion uses secure locking mechanisms for protection. This segmentation reduces overall complexity compared to using secure connections throughout.

AI summary
A modular power supply (1) includes a primary input portion (2) operating with predetermined input parameters, and an output portion (3) comprising at least two modules (4) to be selected for modifying the power supply's output parameters. It is further provided a container (5) in which the primary input portion and the output portion are housed. The container comprises an inaccessible portion (6) adapted to house the primary input portion separated from the output portion, and a cover (7) hinged on a base structure (8) of the container for access to the output portion. The inaccessible portion of the container comprises a partition (9) disposed between the primary input portion and the output portion and provided with openings (10) for cooling the primary input and secondary portions. The openings are such disposed that access to the primary input portion is not allowed.
