Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current avionics bay chairs face challenges in calibrating ventilation flow due to manual and error-prone plug installation, risk of seal degradation, and variable ventilation orifice volumes affecting airflow distribution and module cooling efficiency.
Innovation Solution
The design features a fluidic interface wall with a ventilation plate and diffusion chamber, allowing for easy calibration and sealing by selecting from multiple plates with specific permeability, reducing manual errors and ensuring consistent airflow through a resilient gasket and elastic tabs, maintaining optimal ventilation flow and module support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual plug installation is used to calibrate ventilation flow, then ventilation calibration can be performed, but the process is error-prone and difficult to automate
Solution Approach 1:
The invention divides the calibration function into separate standardized plug elements that can be individually selected and installed. Each plug corresponds to a specific calibration value, allowing precise ventilation flow calibration while enabling automated selection and installation processes, thus resolving the contradiction between measurement precision and ease of manufacture.
2Reliability
If lip seal is exposed on the chair, then sealing function is provided, but the seal is vulnerable to accidental degradation and mechanical friction
Solution Approach 1:
The invention incorporates a protective cap that covers the lip seal before the module is installed. This preliminary protective action prevents accidental degradation and mechanical friction during installation and maintenance operations, thereby maintaining sealing integrity while eliminating exposure to harmful factors.
3Productivity
If standardized chairs with fixed number of ventilation openings are used, then industrial production rationalization is achieved, but ventilation flow calibration becomes complex and manual
Solution Approach 1:
The invention enables ventilation flow calibration by changing the parameter of opening quantity in a standardized manner. Different numbers of openings are provided as discrete options, allowing precise control of ventilation flow while maintaining standardized chair structures for efficient industrial production. This resolves the contradiction by making calibration a simple selection process rather than a complex manual procedure.
