Pressurized Cylinder Bonnet with Color-Coded Pressure Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressurized fluid cylinders lack a reliable and visible indication of the remaining fluid quantity from a distance, as conventional pressure gauges and pistons may not provide sufficient information about the fluid level, especially from afar.
Innovation Solution
The cylinder design incorporates a bonnet with viewing windows to display the position or state of a mobile information support, which moves between distinct positions to symbolize different pressure levels, using a return member to ensure visibility and independence from piston movement, allowing for multiple pressure-sensitive pistons to command distinct positions and states of the information support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional pressure gauge is mounted on the valve assembly and protected by a bonnet, then the pressure indication is provided, but the visibility from a distance is insufficient
Solution Approach 1:
The patent employs color-coded information supports (e.g., green for high pressure, yellow for medium pressure, red for low pressure) that are visible through openings in the bonnet. This color-based visual indication system allows users to quickly assess pressure levels from a distance without needing to read detailed gauge measurements, thereby improving visibility while maintaining indication reliability.
Solution Approach 2:
The patent transitions from a traditional gauge reading interface to a multi-dimensional visual display where information supports can be positioned at different heights and depths within the bonnet. The piston's linear movement translates to vertical positioning of colored indicators, creating a three-dimensional visual field that enhances distance visibility while preserving accurate pressure information.
2Measurement precision
If a piston is used to indicate pressure levels, then the pressure-sensitive indication is provided, but the independence from piston movement and visibility are insufficient
Solution Approach 1:
The patent introduces information supports as intermediary elements between the pressure-sensitive piston and the user. These supports (such as colored sleeves or disks) are mechanically linked to the piston but provide a simplified, highly visible visual interface. The intermediaries translate precise piston positioning into easily distinguishable color zones, enhancing both visibility and operational ease while maintaining measurement precision.
Solution Approach 2:
The patent divides the pressure indication range into distinct segments represented by different colored information supports. Each color zone corresponds to a specific pressure range, allowing users to quickly identify pressure levels without interpreting continuous gauge readings. This segmentation enhances visibility and makes the system easier to operate from a distance while preserving accurate pressure measurement through the piston's continuous movement.
3Loss of information
If multiple pistons are used to indicate different pressure levels, then the distinct pressure level indication is provided, but the device complexity increases
Solution Approach 1:
The patent merges multiple pressure indication functions into a single integrated system where one piston controls multiple information supports that move together. Instead of having separate pistons for each pressure threshold, a single piston's position simultaneously determines the visibility state of multiple colored indicators, thereby reducing mechanical complexity while preserving comprehensive pressure information.
Solution Approach 2:
The patent creates a universal indication system where a single piston and information support assembly serves multiple functions: indicating different pressure thresholds, providing color-coded visual feedback, and maintaining operational simplicity. This multi-functional design reduces device complexity compared to multiple independent piston systems while ensuring complete pressure information is conveyed through the unified mechanism.
