Solution Overview

Problem

Conventional faucet devices experience dew condensation inside the waterproof case housing the motor and controller, and the combined housing of these components leads to unnecessary size increase of the faucet main body.

Innovation Solution

The faucet device is designed with separate waterproof cases for the motor and controller, allowing them to be isolated from the bathroom's internal space, with one case communicating with the external space to prevent dew condensation and minimize the overall size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the motor and controller are housed in a single waterproof case, then the structure is simplified, but the size of the waterproof case increases needlessly causing a size increase of the faucet main body

Engineering Contradiction:

Improvestructural complexityVSAvoidsize of waterproof case

Core Design Contradiction:

Device complexityVSVolume of moving object

Solution Approach 1:

The patent divides the waterproof housing into separate compartments: a first waterproof case for the motor and a second waterproof case for the controller. This segmentation allows each component to be housed in its own optimized space, preventing unnecessary size increase while maintaining structural integrity and simplifying individual component protection.

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If the motor and controller are housed in a single waterproof case, then assembly is simplified, but the faucet main body size increases

Engineering Contradiction:

Improveassembly simplicityVSAvoidfaucet main body length

Core Design Contradiction:

Ease of manufactureVSLength of stationary object

Solution Approach 1:

The patent segments the housing into multiple waterproof cases of appropriate sizes for their respective components. This allows the faucet main body to be more compact in length while still providing adequate protection for each component individually, balancing manufacturing simplicity with space efficiency.

Inventive Principle:

Principle #1Segmentation

3Device complexity

If a single waterproof case is used, then sealing is simpler, but dew condensation occurs inside the case

Engineering Contradiction:

Improvesealing structure complexityVSAvoiddew condensation

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the internal space into separate waterproof cases for the motor and controller. This segmentation reduces the internal volume where dew condensation can occur and allows for better ventilation design in each smaller compartment, effectively reducing condensation while maintaining sealing integrity through multiple smaller sealed interfaces.

Inventive Principle:

Principle #1Segmentation

4Object-affected harmful factors

If separate waterproof cases are used for motor and controller, then dew condensation is reduced and size is minimized, but the number of holes for ventilation increases

Engineering Contradiction:

Improvedew condensationVSAvoidnumber of ventilation holes

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines the ventilation functions of multiple waterproof cases through shared communication passages. The first and second waterproof cases communicate with each other and with the external space through coordinated openings, allowing ventilation across multiple compartments while minimizing the total number of external holes required.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A faucet device includes a water discharge part that discharges a hot or cold water and a faucet main body that is arranged inside a bathroom and supplies a hot or cold water to the water discharge part. The faucet main body includes a flow-rate/temperature control part that executes flow rate control and temperature control for a hot or cold water that is discharged from the water discharge part, a motor that drives the flow-rate/temperature control part, a controller that controls driving of the motor, a first waterproof case that houses the motor and isolates the motor from an internal space of the bathroom, and a second waterproof case that houses the controller and isolates the controller from an internal space of the bathroom. The first waterproof case and the second waterproof case are communicated with an external space of the bathroom.
