Solution Overview

Problem

Conventional blood test apparatuses face difficulties in easy maintenance due to the separate attachment and removal of sensor and filter units, leading to potential contamination and increased complexity in operation.

Innovation Solution

A blood test apparatus designed to eject both the sensor unit and filter unit using a single ejecting mechanism, simplifying their removal and replacement, thereby reducing maintenance complexity and preventing contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If sensor unit and filter unit are attached at different locations, then each component can be independently positioned, but maintenance becomes complicated requiring separate removal operations

Engineering Contradiction:

Improvecomponent positioningVSAvoidmaintenance operation

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the sensor unit and filter unit into a single integrated assembly that is positioned and removed together as one unit. This merging eliminates the need for separate removal operations while maintaining the functional separation of components, directly resolving the contradiction between independent positioning and simplified maintenance.

Inventive Principle:

Principle #5Merging (Combining)

2Device complexity

If filter is not attached, then the structure is simpler, but dust and blood can enter the apparatus causing contamination

Engineering Contradiction:

Improvestructural simplicityVSAvoidcontamination

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The filter unit is integrated with the sensor unit into a single assembly that is always attached when the sensor is in place. This ensures the filter is never omitted, preventing contamination from dust and blood, while the integrated design maintains structural simplicity by eliminating separate filter attachment mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If filter becomes dirty, then both sensor and filter must be removed separately for maintenance, but this increases operation time and complexity

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidmaintenance time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The sensor unit and filter unit are combined into a single removable assembly, allowing both components to be removed and cleaned together in one operation. This eliminates the time loss associated with separate removal operations while ensuring the filter is properly maintained for measurement accuracy.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated sensor-filter assembly is designed as a separate modular unit that can be easily detached from the main apparatus. This segmentation allows the entire assembly to be quickly removed for maintenance without disassembling other parts of the device, reducing maintenance time while ensuring proper filter care.

Inventive Principle:

Principle #1Segmentation

4Adaptability or versatility

If multiple components are removed from separate locations, then each component can be accessed independently, but the ejection operation becomes more complex

Engineering Contradiction:

Improvecomponent accessibilityVSAvoidejection operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The sensor unit and filter unit are merged into a single integrated assembly with a unified ejection mechanism. This allows both components to be ejected simultaneously through one operation, simplifying the ejection process while maintaining the ability to access and replace the functional components independently as a unit.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A blood inspection device capable of separately discharging a sensor and a filter by using a single discharger means. The blood inspection device has a housing provided with a circular hollow cylindrical body having an opening. A filter including a filter is provided inside the cylindrical body, and a sensor is provided outside the cylindrical body. A body of the discharger is slidable outside the cylindrical body. A first discharge section of the discharge comes into contact with the sensor unit to push out and discharge it. A second discharge section of the discharger comes into contact with the filter to push out and discharge it.
