Interlock Blocks Prevent Improper Power Supply Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network equipment vendors face issues with improper installation of power supply modules due to their similar appearances, leading to incompatibilities and potential damage to devices, causing malfunctions and service disruptions.
Innovation Solution
The implementation of interlock blocks and flanges on power distribution and supply modules, which are keyed to ensure only compatible modules with specific electrical ratings can be installed, preventing incompatible ones from being used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If power supply modules with similar appearances are used to reduce manufacturing complexity, then ease of manufacture is improved, but improper installation and incompatibility issues arise leading to device damage
Solution Approach 1:
The patent applies asymmetry by introducing keyed interlock blocks with specific geometric shapes that asymmetrically match corresponding keys on power supply modules. This ensures that only compatible modules with matching key geometries can be installed, preventing improper installation while maintaining simple manufacturing processes for the modules themselves.
Solution Approach 2:
The interlock blocks serve as an intermediary mechanism between the power distribution module and power supply modules. These blocks physically mediate the installation process by allowing only correctly keyed modules to be installed, thus preventing incompatibility issues while keeping the power supply modules themselves simple to manufacture.
2Reliability
If interlock blocks with keying mechanisms are added to power distribution modules, then compatibility control and prevention of improper installation are improved, but device complexity increases
Solution Approach 1:
The patent segments the compatibility control function into separate interlock blocks that are distinct from the main power distribution module. This segmentation allows the keying mechanism to be added as a modular component, reducing the overall structural complexity while maintaining effective compatibility control. The interlock blocks can be independently manufactured and installed.
