Solution Overview

Problem

Conventional faucets require complete disassembly from their mounting structure to remove or replace handles, which is time-consuming and can result in damage to the faucet.

Innovation Solution

A faucet handle assembly featuring a handle with a hook that can be inserted into an opening of a base, secured by a fastener, allowing for easy removal and replacement of the handle with minimal faucet disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the faucet is completely disassembled from the mounting structure to remove the handle, then the handle can be removed, but the process becomes time-consuming and may result in damage to the faucet

Engineering Contradiction:

Improvehandle removalVSAvoiddisassembly time

Core Design Contradiction:

Ease of repairVSLoss of time

Solution Approach 1:

The handle assembly is segmented into separable components: a handle body, a spool assembly, and a mounting structure with opening. This segmentation allows the handle to be removed and replaced without disassembling the entire faucet from the mounting structure, thus reducing disassembly time while maintaining repairability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The spool assembly is extracted as a separate removable component from the handle body. The spool can be taken out through the opening in the mounting structure without removing the entire handle assembly from the faucet, enabling maintenance of internal components while keeping the external handle attached.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of repair

If the faucet is completely disassembled from the mounting structure to remove the handle, then the handle can be removed, but the process becomes complex and may result in damage to the faucet

Engineering Contradiction:

Improvehandle removalVSAvoiddisassembly complexity

Core Design Contradiction:

Ease of repairVSDevice complexity

Solution Approach 1:

The handle assembly is divided into modular segments (handle body, spool assembly, mounting structure) that can be independently accessed and maintained. This segmentation simplifies the repair process by allowing targeted access to specific components without requiring complete disassembly of the faucet system.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If conventional faucet handles are permanently fixed, then the faucet structure remains simple, but handle replacement requires complete disassembly

Engineering Contradiction:

Improvehandle interchangeabilityVSAvoidhandle assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The handle assembly transitions from a static permanent fixture to a dynamic removable structure. The opening in the mounting structure and the spool design enable the handle to be dynamically removed and replaced, providing adaptability while maintaining a relatively simple overall structure through modular design.

Inventive Principle:

Principle #15Dynamics
