Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aeronautical pump systems face challenges in ease of assembly and multifunctional connection, requiring separate and independent locking of electrical and hydraulic connections, which complicates the mounting process and exposes connections to harsh environmental conditions.
Innovation Solution
A pump system with integrated electrical, hydraulic, and mechanical connections on a single flat surface, utilizing spring-supported pins and spindles for secure and protected coupling, allowing simultaneous assembly and protection from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrical and hydraulic connections are made separately on different parts of the pump, then each connection can be independently secured, but the assembly process becomes complex and requires multiple independent locking operations
Solution Approach 1:
The patent combines electrical pins and hydraulic spindles on the same flat surface of the pump body, allowing both connections to be established simultaneously during a single assembly operation. This merging of connection types resolves the contradiction by eliminating the need for separate locking operations while maintaining secure connections for both electrical and hydraulic interfaces.
2Ease of operation
If connections are exposed on the pump exterior, then assembly is straightforward, but connections are vulnerable to damage from extreme environmental conditions such as fire, pressure, and temperature
Solution Approach 1:
The patent embeds the electrical pins and hydraulic spindles within the pump body structure, with connection elements nested inside the pump housing rather than exposed on the exterior. This nesting approach protects the connections from environmental hazards like fire and extreme pressure while maintaining assembly simplicity through the integrated flat surface interface.
3Productivity
If multiple connection types are integrated on a single flat surface, then assembly is simplified and connections are protected, but the design and manufacturing precision requirements increase
Solution Approach 1:
The patent creates a universal flat surface interface that accommodates multiple connection types (electrical pins and hydraulic spindles) in a standardized configuration. This multi-functional interface simplifies assembly by providing a common mounting plane while the standardized design of pins and spindles ensures consistent alignment and reduces manufacturing precision requirements.
