Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moving objects, such as aircraft, face challenges in efficiently arranging and maintaining power generation, power supply, and power storage equipment, leading to complexity and potential limitations in performance and maintenance.
Innovation Solution
The equipment is arranged in distinct areas within the moving object, with the power generation module in one area, the power supply module in another, and the power storage module in a third area, each with independent cooling systems and configurations that allow for efficient power distribution and heat management, reducing complexity and enhancing maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If power generation, power supply, and power storage equipment are arranged in distinct areas, then ease of maintenance and system reliability are improved, but device complexity increases due to multiple separate systems
Solution Approach 1:
The power system is divided into three distinct functional modules: power generation equipment (engine and generator), power supply equipment (electric power device), and power storage equipment (battery). Each module is disposed in a separate area within the moving object, allowing independent maintenance and reducing interference between components. This segmentation enables specialized maintenance procedures for each module while improving overall system reliability.
2Reliability
If independent cooling systems are provided for each equipment group, then reliability and protection from heat adverse effects are improved, but device complexity and energy consumption increase
Solution Approach 1:
The cooling system is segmented into three independent cooling circuits, with each area having its own cooling device. The first area (power generation) has a dedicated cooling device, the second area (power supply) has a dedicated cooling device, and the third area (power storage) has a dedicated cooling device. This segmentation allows each component to be cooled independently, preventing heat transfer between modules and improving reliability by isolating thermal management systems.
3Ease of operation
If equipment areas are arranged in a linear sequence in the traveling direction, then ease of operation and access are improved, but the volume required for housing increases
Solution Approach 1:
The equipment areas are arranged not only in the longitudinal direction (traveling direction) but also utilizing the lateral dimension. The first area is disposed in a first area, the second area is disposed in a second area located forward of the first area, and the third area is disposed in a third area located forward of the second area. This linear arrangement in the traveling direction provides easy access for operations while the compact positioning minimizes the overall volume required.
