Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If intelligent modules are integrated into the water outlet device, then the device gains intelligent functions (digital display, lighting, audio, massage), but the device structure becomes complex and the modules cannot be flexibly matched or combined

Engineering Contradiction:
Improveflexibility of intelligent modesVSAvoidstructure of water outlet device
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The intelligent modules (digital display module, lighting module, audio module, massage module) are segmented as separate detachable components that can be independently installed or removed from the water outlet main body through the installation hole, allowing flexible combination without increasing overall device complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The installation hole with connection terminals provides a universal interface that can accommodate multiple types of intelligent modules, enabling the same structural design to support various functions (display, lighting, audio, massage) through module interchangeability

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

2Reliability

If multiple connection terminals are provided for power and signal transmission, then functional modules can be properly powered and controlled, but the risk of water ingress and electrical failure increases

Engineering Contradiction:
Improvepower and signal transmissionVSAvoidwater ingress risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A waterproof seal ring made of flexible material is disposed around the connection terminals within the installation hole, forming a protective barrier that prevents water from reaching the electrical contacts while allowing the terminals to maintain their electrical connection function

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The waterproof seal ring acts as an intermediary element between the electrical connection terminals and the external water environment, isolating the electrical components from water exposure while maintaining the functionality of power and signal transmission

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the installation hole is designed for detachable modules, then module flexibility and maintenance become easier, but the connection reliability between terminals and contact points may be compromised

Engineering Contradiction:
Improvemodule installation and removalVSAvoidconnection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connection terminals are designed to be elastically deformable, allowing them to dynamically adjust their position and shape during module insertion and removal, ensuring reliable electrical contact while maintaining ease of operation for detachable modules

Inventive Principle:
Principle #15Dynamics
