Access Floor Beam Structure for Clean Room Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Access floor systems in clean rooms face challenges in distributing heavy loads and minimizing structural damage from vibrations and stress, particularly during earthquakes, due to the uneven distribution of loads and lack of effective dust removal mechanisms.
Innovation Solution
A structure comprising X-axis and Y-axis beams of equal height, with guide grooves and connection brackets, supported by posts with adjustable nut systems, and seating pads with ribs to securely fasten and stabilize access floor panels, enhancing load distribution and vibration resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If X-axis and Y-axis beams are arranged at different heights to simplify installation, then installation complexity is reduced, but dust removal frame installation becomes difficult and structural stability deteriorates
Solution Approach 1:
The patent employs asymmetric beam height design where X-axis beams and Y-axis beams are positioned at different vertical levels. This asymmetry enables the dust removal frame to be installed on the higher beam while maintaining proper structural support relationships, resolving the contradiction between installation ease and structural stability.
Solution Approach 2:
By introducing vertical dimension differentiation through unequal beam heights, the patent creates three-dimensional spatial arrangement that allows dust removal frames to be properly positioned while maintaining structural integrity. This dimensional approach solves the installation problem without compromising stability.
2Productivity
If beam heights are equalized to facilitate dust removal frame installation, then dust removal efficiency improves, but load distribution and vibration resistance may be compromised
Solution Approach 1:
The patent applies different height specifications to different beam types (X-axis vs Y-axis) based on their specific functional requirements. The X-axis beams are designed at one height to optimize dust removal frame installation, while Y-axis beams are designed at another height to optimize structural support, achieving local optimization rather than uniform design.
3Strength
If the structure is designed to accommodate heavy equipment loads, then load bearing capacity increases, but the structure becomes more vulnerable to shear damage from sudden stress or earthquakes
Solution Approach 1:
The patent incorporates adjustable height mechanisms and flexible connection designs that allow the structure to adapt dynamically to varying loads and stress conditions. This dynamic capability enables the structure to withstand both heavy static equipment loads and sudden dynamic stresses from earthquakes or impact forces.
