Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive modules require structural adjustments to meet UL 508A standards for overcurrent protection, complicating their modular assembly and maintenance.
Innovation Solution
A feed module with a first connection contact and a second connection contact, featuring a fuse element between them, allows for reliable overcurrent protection without structural modifications, enabling modular security compliance and easy connection of multiple drive modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If securing elements are arranged in the drive module to meet UL 508A standards, then overcurrent protection is achieved, but structural modifications are required complicating modular assembly
Solution Approach 1:
The invention separates the securing elements (fuse elements) from the drive module and places them in the feed module instead. This segmentation allows the drive module to remain structurally simple and modular, while the feed module provides the required overcurrent protection functionality.
Solution Approach 2:
The feed module acts as an intermediary between the power supply and the drive module, incorporating the securing elements to provide overcurrent protection without requiring modifications to the drive module itself. This mediator approach resolves the contradiction by placing protection functionality in the intermediate component.
2Reliability
If securing elements are integrated into the drive module, then protection is provided, but adaptability to different standards and motors is reduced
Solution Approach 1:
The feed module is designed with universal adaptability to work with different drive modules and motor configurations. By placing securing elements in the feed module rather than the drive module, the system can be adapted to various UL standards and motor requirements without redesigning the drive module itself.
Solution Approach 2:
The invention allows for parameter changes in the feed module (such as different fuse ratings and configurations) to accommodate different standards and motor requirements, while the drive module remains unchanged. This enables flexibility and adaptability at the feed module level.
3Reliability
If fuse distribution boxes with multiple printed circuit boards are used, then current limiting is achieved, but device complexity increases
Solution Approach 1:
The invention extracts the essential current limiting function from complex multi-board fuse distribution boxes and implements it in a simplified feed module design. The securing elements are directly connected to the connection contacts without requiring multiple printed circuit boards, maintaining current limiting reliability while reducing structural complexity.
