Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-size faucet handle is designed for a specific faucet base size, then the handle can be precisely matched to that base size, but it cannot be used with faucet bases of other sizes, reducing versatility

Engineering Contradiction:

Improvecompatibility with different faucet base sizesVSAvoidstructure of faucet handle

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The faucet handle is divided into two separable parts: a universal handle body and a size-specific conversion block. The conversion block is detached and can be replaced depending on the faucet base size, allowing the same handle body to adapt to different base dimensions without increasing overall structural complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The handle body is designed with universal features that can work with multiple faucet base sizes through the use of different conversion blocks. The receiving space in the handle body is configured to accommodate various conversion blocks, enabling one handle design to serve multiple functions across different faucet configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If customers purchase faucet handles without considering exact size matching, then the selection process becomes simpler, but assembly and replacement become difficult due to size incompatibility

Engineering Contradiction:

Improveease of assembly and replacementVSAvoidtime for assembling and replacing faucet handles

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The appropriate conversion block is selected and pre-installed on the handle body before assembly with the faucet base. This preliminary configuration ensures size compatibility is established in advance, making the subsequent assembly process straightforward and reducing the time required for installation and future replacements.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the control handle allows full rotation, then complete control range is achieved, but water flow cannot be reduced to minimum and excessive water flow and temperature may occur

Engineering Contradiction:

Improvecontrol range of faucetVSAvoidexcessive water flow and temperature

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The restricting device is pre-configured with a stopping block positioned to limit the rotation angle of the control handle. This preliminary restriction prevents the handle from rotating beyond the safe position, thereby preventing excessive water flow and temperature before they can occur, while still allowing sufficient control range for normal operation.

Inventive Principle:

Principle #9Preliminary anti-action

4Object-affected harmful factors

If a restricting device is added to limit control handle rotation, then water flow and temperature can be controlled, but the device complexity increases

Engineering Contradiction:

Improveexcessive water flow and temperatureVSAvoidstructure of control handle

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The restricting device is integrated into the existing control handle structure by incorporating the sleeve and stopping block as unified components with the handle assembly. The stopping block is positioned within the receiving space, and the sleeve is mounted on the control pole, merging the restriction function with the handle's existing mechanical structure rather than adding completely separate components.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A wall-mounted faucet control component includes a control handle, a conversion block and a restricting device, wherein two spaced protruding ribs are located at the periphery of the opening of a receiving space of the control handle, and a connecting pole is protrudingly formed at the center of the opening surface of the receiving space. The conversion block is located at the receiving space of the control handle, wherein two recessed slots are spacedly and recessedly formed at the periphery of the conversion block, and the recessed slots are engaged with the protruding ribs of the control handle. According to the abovementioned structure, since the detachable conversion block is formed at the receiving space of the control handle, it can be used for water control bases of different sizes to increase the practicability of the faucet handle and increase the convenience in assembly process.
