Solution Overview

Problem

Hydraulic power packs require different mounting configurations depending on their location and use in an aircraft, leading to increased design costs and time to market due to the need for specific mounting configurations being identified before design work can begin.

Innovation Solution

A hydraulic power pack arrangement with an adjustable mounting system that allows for rotational adjustment of the core assembly and reservoir assembly relative to a mounting bracket, enabling multiple mounting configurations such as floor, ceiling, and wall mounts, facilitating design before a specific location is chosen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed mounting configuration is designed for the hydraulic power pack, then the design can be completed and manufactured, but the design cost and time to market increase because the mounting location must be identified before design work can begin

Engineering Contradiction:
Improvemounting configuration adaptabilityVSAvoidtime to market
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The mounting bracket assembly is designed with multiple mounting interfaces and adjustable positioning mechanisms that enable the hydraulic power pack to be mounted in various configurations (floor, ceiling, wall, or rack mounting) without requiring different design versions. This universal mounting capability allows the same design to serve multiple mounting locations and applications, eliminating the need to wait for mounting location identification before design completion.

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

2Adaptability or versatility

If different mounting configurations are designed for different aircraft locations, then each specific mounting requirement can be met, but the design complexity and cost increase

Engineering Contradiction:
Improvemounting configuration adaptabilityVSAvoiddesign complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of creating separate designs for floor mounting, ceiling mounting, wall mounting, and rack mounting configurations, the invention employs a single mounting bracket assembly that incorporates all these mounting capabilities through adjustable interfaces and reconfigurable attachment mechanisms, thereby reducing design complexity while maintaining versatility.

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

Solution Approach 2:

The mounting bracket assembly incorporates adjustable and reconfigurable elements that allow it to adapt dynamically to different mounting requirements. The bracket can be positioned and secured in various orientations and locations, providing the flexibility of multiple fixed designs through a single dynamic structure.

Inventive Principle:
Principle #15Dynamics
