Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metal enclosures in vibratory meters block wireless signals, preventing communication and control operations, especially in hazardous or explosive environments where aperture adjustments are constrained.
Innovation Solution
A metal housing with an etched antenna slot filled with a fiber-reinforced resin compound allows wireless data transmission, maintaining structural integrity and enabling communication through the compound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal housing is used for structural integrity and safety, then strength and reliability are improved, but wireless signal transmission is blocked
Solution Approach 1:
The housing is segmented into metal portions providing structural integrity and a compound portion (antenna slot filled with fiber-reinforced resin) providing wireless signal permeability. This segmentation allows different regions to fulfill different functions - the metal housing maintains strength while the compound-filled antenna slot enables wireless communication.
Solution Approach 2:
The invention uses composite materials by filling the antenna slot with a fiber-reinforced resin compound. This composite material combines the structural properties of resin with the signal-permeable characteristics required for wireless communication, allowing the housing to simultaneously achieve strength and wireless signal transmission.
2Loss of information
If apertures are created in the housing for wireless transmission, then wireless signal transmission is improved, but structural integrity and safety are compromised
Solution Approach 1:
Instead of creating apertures in the metal housing, the invention uses a composite material approach by filling the antenna slot with fiber-reinforced resin compound. This composite material maintains the housing's structural integrity while inherently providing wireless signal permeability, eliminating the need for apertures that would compromise strength.
Solution Approach 2:
The antenna slot region is given local quality different from the rest of the housing by filling it with a specialized fiber-reinforced resin compound. This localized modification provides wireless signal transmission capability only where needed, while the remainder of the metal housing maintains its full structural integrity.
