Solution Overview

Problem

Traditional hydraulic power systems for aircraft require specific mounting configurations, which can lead to increased design costs and longer time-to-market due to the need for customized solutions before identifying a specific mounting location or configuration.

Innovation Solution

A hydraulic power pack arrangement with a core assembly and reservoir assembly that are rotationally adjustable relative to a mounting bracket, allowing for multiple mounting configurations such as floor, ceiling, and wall mounts, enabling flexible design and installation without pre-identifying a specific mounting location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional hydraulic power packs are designed with fixed mounting configurations, then the design can be completed and manufactured, but the design cost increases and time-to-market lengthens due to the need to identify specific mounting locations before finalizing the design

Engineering Contradiction:
Improvemounting configuration flexibilityVSAvoiddesign completion time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The mounting bracket assembly incorporates rotational adjustment mechanisms that allow the hydraulic power pack core assembly and reservoir assembly to be rotated to different orientations after manufacturing. This dynamic adjustability enables the same unit to adapt to multiple mounting configurations (floor, ceiling, wall mounts) without requiring pre-determination of the mounting location, thereby reducing design time and accelerating time-to-market while maintaining design flexibility

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting bracket assembly is designed as a universal mounting solution that can accommodate various mounting configurations through rotational adjustment. The bracket assembly includes multiple mounting interfaces and rotational adjustment capabilities that allow a single hydraulic power pack design to serve multiple mounting locations and configurations, eliminating the need for customized designs for each specific application

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If traditional hydraulic power packs are designed with fixed mounting configurations, then the design can be completed and manufactured, but the design cost increases due to the need for customized solutions before identifying specific mounting locations

Engineering Contradiction:
Improvemounting configuration flexibilityVSAvoiddesign cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The mounting bracket assembly is designed as a universal mounting solution that can accommodate various mounting configurations through rotational adjustment. The bracket assembly includes multiple mounting interfaces and rotational adjustment capabilities that allow a single hydraulic power pack design to serve multiple mounting locations and configurations, eliminating the need for customized designs for each specific application and thereby reducing design costs

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The hydraulic power pack is divided into separable assemblies (core assembly and reservoir assembly) that can be independently positioned and rotated relative to each other and to the mounting bracket. This segmentation allows for flexible configuration adjustment without requiring custom-designed integrated units for each mounting scenario, reducing overall design complexity and cost

Inventive Principle:
Principle #1Segmentation
