Solution Overview
Problem
Existing particle measuring systems face challenges in maintaining accuracy and convenience due to the need for frequent replacement of dehumidifying agents, especially in high-humidity environments, which affects the continuity and precision of fine particle measurements.
Innovation Solution
A particle measuring system with two drying units, where one unit dries fine particles and the other regenerates the dehumidifying agent using regenerative drying means, allowing the dehumidifying agent to be used semi-permanently without replacement, and utilizing discharged dry air for regeneration, along with heaters for efficient temperature adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single drying unit uses a dehumidifying agent to dry fine particles, then the structure remains simple and easy to fabricate, but the dehumidifying agent must be periodically replaced due to performance deterioration
Solution Approach 1:
The single drying unit is divided into two separate drying units: a first drying unit for drying fine particles and a second drying unit for regenerating the dehumidifying agent. This segmentation allows the dehumidifying agent to be continuously regenerated without interruption, eliminating the need for periodic replacement and maintaining measurement continuity.
Solution Approach 2:
Instead of discarding the dehumidifying agent after it loses effectiveness, the system recovers it by directing dry air from the first drying unit to the second drying unit, where the dehumidifying agent is regenerated. This recovery process extends the usable life of the dehumidifying agent indefinitely.
2Ease of operation
If the dehumidifying agent is not replaced at the correct time, then operational convenience is maintained, but the accuracy of particle measurements is significantly lowered
Solution Approach 1:
The system incorporates a controller that monitors the drying performance and automatically switches between the first and second drying units based on real-time conditions. This feedback mechanism ensures that measurements are always performed when the dehumidifying agent is in optimal condition, maintaining measurement accuracy without requiring manual intervention.
Solution Approach 2:
The system periodically switches between the first drying unit (for measurement) and the second drying unit (for regeneration) in a cyclic manner. This periodic action ensures that the dehumidifying agent is continuously regenerated before being used again, maintaining consistent measurement accuracy throughout operation.
3Duration of action of stationary object
If two drying units are implemented with regenerative drying means, then the dehumidifying agent can be regenerated semi-permanently, but the device complexity increases
Solution Approach 1:
The system merges the drying function and regeneration function into a unified dual-unit structure where both functions share common components such as the controller, air circulation system, and dehumidifying agent material. This merging approach reduces overall system complexity compared to having completely separate systems.
Solution Approach 2:
Each drying unit is designed to perform multiple functions: the first drying unit serves both for drying fine particles and for providing dry air to regenerate the dehumidifying agent in the second unit. This multi-functionality reduces the need for additional dedicated components, simplifying the overall system structure.
4Loss of time
If regenerative drying means are added to enable dehumidifying agent regeneration, then dehumidifying agent replacement is eliminated, but energy consumption increases
Solution Approach 1:
The system uses its own operational byproducts to sustain itself: the dry air produced during the normal drying operation in the first drying unit is redirected to the second drying unit to regenerate the dehumidifying agent. This self-service approach uses internally generated resources for regeneration, minimizing additional energy input requirements.
Solution Approach 2:
The system converts what would otherwise be wasted dry air from the first drying unit into a valuable resource for regenerating the dehumidifying agent in the second drying unit. This conversion transforms a potential waste stream into a beneficial input, reducing the overall energy demand of the system.

AI summary
A particle measuring system including two drying units. One drying unit serves to dry fine particles, and the other drying unit serves to regenerate a dehumidifying agent. The dehumidifying agent is regenerated and used semi-permanently without being replaced with a replacement and is used more conveniently without the inconvenience of a dehumidifying agent replacing operation. The continuity and accuracy of a measurement result is improved.
