Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods are used to test radio communication characteristics in actual aircraft, then measurement accuracy is improved, but cost and time consumption increase significantly
Solution Approach 1:
The patent creates a portable casing that copies the essential geometric characteristics of an aircraft fuselage without requiring an actual aircraft. The casing includes a frame structure with specific geometric parameters (lengths a, b, c and angles α, β, γ) that model the fuselage shape, allowing radio communication tests to be conducted in a simplified, cost-effective environment while maintaining measurement accuracy relevant to actual aircraft conditions.
2Reliability
If a complete aircraft is used for testing, then realistic testing conditions are achieved, but device complexity and cost increase
Solution Approach 1:
The patent segments the complex aircraft structure into essential geometric elements represented by the portable casing. The casing includes a frame with specific geometric parameters (lengths a, b, c and angles α, β, γ) that capture the fuselage shape without requiring the complete aircraft. This segmentation maintains testing realism while significantly reducing system complexity and cost.
Solution Approach 2:
The patent applies local quality by focusing on the specific geometric characteristics of the fuselage that are most relevant to radio communication propagation. The casing incorporates specific dimensional parameters (lengths a, b, c and angles α, β, γ) that model the local geometry affecting radio signals, rather than requiring the entire aircraft structure. This approach maintains testing reliability for radio communication characteristics while reducing overall system complexity.
3Measurement precision
If fixtures and fittings are arranged in the casing to model aircraft interior, then measurement accuracy is improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the aircraft interior into discrete fixtures and fittings that can be individually arranged within the portable casing. The casing includes a frame structure with mounting points for seats, tables, and other interior elements, allowing these components to be arranged to model specific aircraft configurations. This segmentation enables accurate measurement of radio signal propagation in different interior arrangements while maintaining ease of manufacture through modular assembly.
