Fuse Switch Guide Rail Mechanism for One-Motion Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuse switches require multiple steps and user knowledge to transition to the parked position, often leading to incorrect operations without instructions, and lack intuitive design for quick and stable parking.
Innovation Solution
A fuse switch design featuring a guide rail with interconnected guide grooves and toothed elements allowing a single, smooth lever movement to transition from closed to parked position, ensuring stable locking and easy access to functional elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the switch is designed with separate opening and parking operations, then the circuit protection function is reliable, but the operating complexity increases and requires multiple steps
Solution Approach 1:
The patent combines the circuit opening function and parking function into a single lever operation. When the lever is actuated, it simultaneously disconnects the circuit and positions the fuse cartridge holder in the parked position, eliminating the need for separate operations and reducing complexity while maintaining reliability
2Stability of the object's composition
If the parking position mechanism is designed with multiple components and instructions, then the stability of parked position is improved, but the ease of operation deteriorates due to requiring user knowledge and multiple steps
Solution Approach 1:
The mechanism is designed to be self-explanatory and self-operating. The lever's movement path and the fuse cartridge holder's positioning are designed so that the parking action occurs automatically as part of the opening operation, without requiring users to consult instructions or perform separate steps. The design itself guides the user through the correct operation
3Volume of moving object
If the manipulator design is compact to close switchgear door, then the device size is reduced, but the ability to secure the manipulator in parked position is limited
Solution Approach 1:
The lever is designed to serve multiple functions: it acts as the operating handle for opening/closing the circuit, serves as the manipulator for parking the fuse cartridge holder, and provides a mounting surface for padlocks or sealing elements. This multi-functionality allows compact design while maintaining the ability to secure the device in the parked position
