Solution Overview

Problem

Existing cleaning implements require different adaptors or sockets for various handle types, making it impractical and time-consuming to switch between them.

Innovation Solution

A socket with a cylindrical wall featuring slots and splines that accommodate different handle types, providing a compression or interference fit for stability and engagement, eliminating the need for multiple sockets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different adaptors or sockets are used for different handle types, then each handle type can be properly attached, but the device complexity and number of components increases

Engineering Contradiction:
Improvehandle compatibilityVSAvoidnumber of sockets
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The socket is designed with a universal structure that can accommodate multiple handle types (threaded handles, solid handles, lobe-shaped handles) through a single multi-functional design. The cylindrical wall with slots and splines creates a standardized interface that works with various handle geometries, eliminating the need for multiple specialized sockets.

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

Solution Approach 2:

The socket structure is segmented into functional zones: the cylindrical wall provides the basic receptacle, slots provide attachment points for different handle types, and splines provide gripping surfaces. This segmentation allows each element to contribute to handling different handle types while maintaining a unified socket design.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple sockets are carried for different handle types, then all handle types can be supported, but portability and practicality deteriorate

Engineering Contradiction:
Improvehandle type supportVSAvoidportability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

By designing a single socket that can universally accommodate multiple handle types through its slots and splines configuration, the need to carry multiple specialized sockets is eliminated. Users only need one socket to work with various handle types, significantly improving portability and ease of operation.

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

3Adaptability or versatility

If different sockets are changed for different handles, then proper attachment is achieved, but time efficiency decreases

Engineering Contradiction:
Improvehandle attachmentVSAvoidsocket changing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The socket is pre-configured with multiple slots and splines that are positioned to accommodate different handle types without requiring socket replacement. The slots are arranged to receive various handle geometries, and the splines are positioned to engage with different handle profiles, allowing users to simply insert the appropriate handle directly into the pre-prepared socket.

Inventive Principle:
Principle #10Preliminary action

4Device complexity

If a single socket design is used for all handle types, then simplicity is improved, but attachment reliability may worsen

Engineering Contradiction:
Improvesocket designVSAvoidattachment stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

Different regions of the socket have specialized features tailored to specific handle types: slots provide attachment points for lobe-shaped handles, while splines provide gripping surfaces for threaded and solid handles. This local differentiation within a unified socket design ensures reliable attachment for each handle type without requiring multiple specialized sockets.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The socket design allows for dynamic engagement where the slots and splines can adapt to different handle geometries. The slots can receive various handle profiles, and the splines can engage with different handle surfaces, providing reliable attachment through flexible geometric accommodation rather than rigid fixed geometry.

Inventive Principle:
Principle #15Dynamics
