Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic transfer switching equipment (ATSE) state indicating modules are inconvenient for maintenance and lack scalability, as they often integrate micro switches within the product and use connectors as interfaces, making installation and expansion difficult.
Innovation Solution
The state indicating module incorporates a micro switch arrangement that allows for easy installation and maintenance, with expandable capabilities, using transmission assemblies with pushing and oscillating rods and return springs to trigger micro switches based on power supply states, and a hook-slot assembly for quick attachment, enabling reliable on/off signal output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the micro switch is integrated inside the ATSE product with connector interface, then the structural integration is improved, but the ease of maintenance and scalability deteriorates
Solution Approach 1:
The state indicating module is divided into independent functional components: micro switch assembly, transmission assembly, and housing. The micro switch is mounted on a circuit board that forms a self-contained module, which can be easily removed and replaced without affecting the entire ATSE system. This segmentation enables independent maintenance of the indication function.
Solution Approach 2:
The micro switch and its associated transmission mechanism are extracted from the integrated ATSE structure and placed into a separate state indicating module. This module can be independently installed, removed, and maintained without disassembling the main ATSE device, significantly improving ease of repair and maintenance.
2Device complexity
If the micro switch is integrated inside the ATSE product with connector interface, then the structural integration is improved, but the scalability deteriorates
Solution Approach 1:
The state indicating module is designed as a universal, standalone unit that can be applied to different ATSE configurations. The module accepts various driving rod positions and can indicate different power supply states through a standardized interface, making it scalable across different application scenarios without requiring custom integration for each case.
Solution Approach 2:
The module incorporates adjustable transmission assemblies that can adapt to different driving rod positions and movement characteristics. The oscillating rod and pushing rod mechanisms can be configured to respond to various switching scenarios, enabling the same module design to scale across different ATSE specifications and customer requirements.
3Reliability
If a transmission assembly with oscillating rod and pushing rod is used, then the reliability of state indication is improved, but the device complexity increases
Solution Approach 1:
The transmission assembly merges multiple functions into a compact mechanism: the oscillating rod converts linear motion from the driving rod into rotational motion, which then actuates the micro switch through the pushing rod. This integrated transmission mechanism ensures reliable state indication while minimizing the number of separate components and assembly steps within the module.
Solution Approach 2:
The transmission assembly is designed to automatically respond to driving rod movement without requiring external control or adjustment. The oscillating rod and pushing rod form a self-actuating mechanism that reliably triggers the micro switch based on the physical position of the driving rod, ensuring consistent and maintenance-free operation.
4Ease of operation
If the state indicating module is made small and modular, then the ease of installation is improved, but the transmission mechanism complexity increases
Solution Approach 1:
The transmission mechanism is nested within a compact housing structure. The oscillating rod rotates within the housing, and the pushing rod is positioned to engage with the micro switch button. This nested arrangement accommodates the transmission mechanism in a small footprint while maintaining all necessary functional clearances and movement ranges.
Solution Approach 2:
The transmission mechanism utilizes three-dimensional spatial arrangement to achieve compact design. The oscillating rod rotates in a plane perpendicular to the pushing rod's linear motion, creating an efficient use of space. The micro switch is positioned to receive actuation from the pushing rod while maintaining clearance for the oscillating rod's rotation, enabling a small module size without sacrificing transmission reliability.
