Solution Overview

Problem

Existing suction-extraction coupling adapters for suction appliances are not universally compatible with different power tools, limiting their use across various hand-held power tools.

Innovation Solution

A suction-extraction coupling adapter equipped with a sensor device that establishes communication between a power tool and a suction appliance, enabling universal compatibility by sensing operating signals from the power tool and transmitting them wirelessly to the suction appliance, thereby controlling the suction process independently of the power tool manufacturer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a suction-extraction coupling adapter is designed for specific power tool compatibility, then connection reliability is improved, but adaptability to different power tool manufacturers deteriorates

Engineering Contradiction:

Improveconnection reliabilityVSAvoidadaptability to different power tool manufacturers

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The adapter incorporates a sensor device that can detect operating signals from different power tool manufacturers, enabling the same adapter to universally interface with various power tools while maintaining reliable suction extraction functionality. The sensor device acts as a universal communication interface that translates between different power tool signal protocols and the suction appliance control system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If communication between power tool and suction appliance is established, then adaptability and control capability are improved, but device complexity increases

Engineering Contradiction:

Improveuniversal compatibilityVSAvoidcommunication interface complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sensor device serves as an intermediary component between the power tool and suction appliance, receiving operating signals from the power tool and transmitting processed control signals to the suction appliance. This mediator approach enables universal compatibility without requiring complex direct communication protocols between all possible power tool and suction appliance combinations.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces complex mechanical or electrical direct-connect communication systems with a sensor-based detection and wireless transmission system. The sensor device detects operating signals and uses wireless communication (such as Bluetooth or WiFi) to transmit data, eliminating the need for complex wired communication interfaces.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If sensor device is added for communication capability, then adaptability and control are improved, but manufacturing cost increases

Engineering Contradiction:

Improveuniversal communication capabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent replaces expensive complex wired communication systems with more cost-effective sensor devices combined with wireless communication technology. This substitution reduces manufacturing costs while maintaining or improving adaptability and control capabilities.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
