Solution Overview
Problem
Existing fluid transfer equipment for motor vehicles and energy sectors requires improved maintenance accessibility and ergonomics, as current solutions necessitate disassembling the chassis to access valves, leading to time-consuming operations and potential loss of small parts.
Innovation Solution
The equipment features a piston valve with a mobile body and a module that allows for easy insertion and removal, utilizing pneumatic or hydraulic control systems and sealing gaskets to ensure sealing and facilitate operator access, with the module's open position allowing for valve release from their housings for simplified maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If valves are assembled directly in the chassis, then the equipment structure is compact, but maintenance becomes time-consuming and requires disassembly of the chassis
Solution Approach 1:
The equipment is divided into modular components: the chassis, the module containing the piston valve, and the valve itself. This segmentation allows the valve to be easily removed and replaced without disassembling the entire chassis, resolving the contradiction between compact structure and ease of maintenance.
Solution Approach 2:
The piston valve is extracted as a separate, removable component from the chassis. The valve can be taken out of its housing in the chassis for maintenance or replacement, eliminating the need to disassemble the chassis structure while maintaining a compact overall design.
2Ease of repair
If the chassis is disassembled to access valves, then valve maintenance is possible, but small parts may be lost and operations become time-consuming
Solution Approach 1:
The piston valve is designed as an extractable component that can be removed from its housing in the chassis without disassembling the chassis itself. This extraction capability allows maintenance personnel to access and replace valves quickly, eliminating the time-consuming disassembly process and the risk of losing small parts.
Solution Approach 2:
The piston valve is designed as a replaceable component that can be quickly swapped out during maintenance. This approach treats the valve as a consumable or easily replaceable part, reducing maintenance time and complexity by allowing direct replacement rather than repair of complex integrated systems.
3Device complexity
If valves are integrated into the chassis, then the equipment is compact, but operator safety and ergonomics are compromised
Solution Approach 1:
The equipment is segmented into the chassis and removable valve modules. This segmentation allows operators to safely handle and replace valves without working within the confined and potentially hazardous space of the integrated chassis, improving ergonomics and operator safety while maintaining compact equipment design.
Solution Approach 2:
The piston valve is extracted as a separate handleable component that can be safely removed from the chassis. This extraction allows operators to perform maintenance tasks outside the chassis structure, improving accessibility and reducing safety risks associated with working inside the integrated equipment.
