Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid level sensors face challenges in accurately measuring slow fluid consumption rates in environments prone to vibrations and bubbling, such as hydrogen peroxide vaporizers, due to interference from gas emissions and turbulence.
Innovation Solution
A reservoir assembly with a float member and fluid column level sensor, where the float member is partially submerged and designed with passageways and sidewall guide surfaces to absorb vibrations and allow bubble passage, coupled with an ultrasonic sensor to determine the float's position and measure fluid levels accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional fluid level sensors are used in hydrogen peroxide vaporizers, then fluid level can be detected, but measurement accuracy deteriorates due to vibrations and bubbling from the fluid
Solution Approach 1:
The patent introduces a float member as an intermediary between the fluid and the sensor. The float absorbs vibrations and turbulence from bubbling hydrogen peroxide, providing a stable mechanical interface for the sensor to measure fluid level without direct exposure to harmful fluid dynamics
Solution Approach 2:
The patent replaces direct mechanical contact sensors with an ultrasonic sensor that measures fluid level by detecting the position of the float through acoustic waves. This non-contact measurement approach eliminates the harmful effects of vibrations and bubbling on the sensing mechanism
2Stability of the object's composition
If the float member is completely submerged to improve stability, then vibration absorption improves, but bubble passage is blocked
Solution Approach 1:
The patent applies local quality by making only the lower portion of the float member submerged in the fluid while keeping the upper portion exposed. This localized submersion provides sufficient vibration absorption stability while maintaining bubble passage through the unobstructed upper region
Solution Approach 2:
The float member is segmented into submerged and non-submerged portions, each serving different functions. The submerged lower portion absorbs vibrations and provides stability, while the exposed upper portion allows bubbles to pass through freely
3Productivity
If the float member is made smaller to reduce interference with fluid flow, then bubble passage improves, but vibration absorption capability deteriorates
Solution Approach 1:
The patent optimizes the float member's dimensional proportions, creating an elongated structure with specific length-to-diameter ratios. This dimensional configuration provides sufficient vibration absorption surface area while maintaining compact cross-sectional dimensions that minimize interference with fluid and bubble flow

AI summary
The disclosure is directed to reservoir assembly for storing hydrogen peroxide for use with a hydrogen peroxide vaporizer in association with a filler. Which includes a fluid chamber, a float member and a column level sensor. The float member is positioned within the fluid chamber. The fluid column level sensor is positioned at or near the upper end of the fluid chamber. The float member is configured to absorb the vibrations, turbulence and bubbling caused by the fluid movement and degradation. To that end, the float member is configured so as to be partially submerged. In addition, the float member includes an outer surface that has both passageways and sidewall guide surfaces which facilitate proper tracking within the fluid chamber, while also allowing for the directing of fluid movements around the float.
