Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If air treatment devices provide automatic operational modes with sensors, then the flexibility and adaptability of the device is improved, but the device complexity and cost increase

Engineering Contradiction:
ImproveflexibilityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sensor module is separated from the air treatment device into an independent detachable component. This segmentation allows the device to offer advanced automatic operation capabilities when needed while keeping the base unit simple and affordable. Users can attach the sensor module only when they require automatic operational modes, thus gaining flexibility without permanently increasing device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable sensor module can be used with multiple different air treatment devices through standardized mating means. This universal design allows a single sensor module to enhance the functionality of various device models, providing automatic operational capabilities across different product lines without requiring each device to have built-in sensors.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If air treatment devices provide automatic operational modes with sensors, then the adaptability to varying air quality needs is improved, but the manufacturing cost increases

Engineering Contradiction:
ImproveadaptabilityVSAvoidcost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By segmenting the sensor module as a separate detachable component, manufacturers can produce simple air treatment devices at lower costs and add the expensive sensor functionality only when customers purchase the optional module. This reduces the baseline manufacturing cost while still providing adaptability to customers who need it.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sensor module is designed as an affordable, replaceable component that can be produced at lower costs than integrated solutions. Users can attach or remove the module based on their needs, and if damage or unauthorized removal occurs, the module can be easily replaced without affecting the main device, reducing overall system cost risk.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If the sensor module is placed outside the device, then the ease of access for maintenance is improved, but the risk of unauthorized removal and damage increases

Engineering Contradiction:
ImproveaccessibilityVSAvoidrisk of damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The sensor module is designed to nest within a recess of the air treatment device when attached. This nesting provides physical protection for the sensors and connector while still allowing easy insertion and removal by users. The recess acts as a protective housing that shields the delicate components during normal operation but doesn't prevent authorized access for maintenance.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Ease of repair

If a detachable sensor module is used, then the ease of repair and replacement is improved, but the reliability of data connection may worsen

Engineering Contradiction:
ImprovereplaceabilityVSAvoidconnection reliability
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The connector and recess are designed with preliminary alignment features such as guide rails, positioning pins, or keyed interfaces that ensure correct orientation and secure mating before data transmission begins. This preliminary action prevents misconnection and ensures reliable data connection while maintaining easy replaceability through a straightforward plug-and-play interface.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present specification relates to an air treatment device (200) and a detachable sensor module (100). The air treatment device comprises a user interface configured to display, for selection by a user, at least one static or open-loop operational mode to be executed by a controller; and a wall comprising one or more pervious sections towards an ambient volume. One side of the wall comprises a connector for mating with a corresponding connector of the detachable sensor module (100), and the connector, when the sensor module is present, enables a data connection from the sensor module to the controller. When the data connection is enabled, the user interface is configured to display at least one closed-loop operational mode, in which the controller controls the air treatment section in response to measurement data relating to the ambient volume received from the sensor module.
