Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional bath caddies are used to provide basic functionality, then the structure remains simple and cost-effective, but the bathing experience lacks relaxation and immersion

Engineering Contradiction:
Improvecustomizable featuresVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into a single bath caddy unit: the tray structure provides basic item placement, while integrated lighting assemblies with controllable LEDs, user interfaces, and controllers are merged into the same device. This allows customizable lighting features to be added without requiring separate devices, resolving the contradiction between enhanced adaptability and structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bath caddy is designed as a multi-functional device that serves both as a traditional item-holding tray and as an illuminated ambiance creator. The lighting assembly can operate in multiple modes (different colors, tones, brightness levels) to provide various bathing experiences, making the single device adaptable to different user needs and preferences.

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

2Adaptability or versatility

If lighting assembly with controller and user interface is added to the bath caddy, then customizable lighting modes are achieved, but the device complexity increases

Engineering Contradiction:
Improvelighting customizationVSAvoidcontrol system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lighting assembly incorporates a user interface that allows bathers to directly control lighting parameters (color, brightness, mode) without requiring external control devices or complex wiring. The system serves itself by providing intuitive controls integrated into the bath caddy structure, enabling users to customize lighting experiences while keeping the control system manageable.

Inventive Principle:
Principle #25Self-service

3Illumination intensity

If light fixtures are integrated into the bath caddy tray, then illumination for immersive bathing is provided, but the manufacturing complexity increases

Engineering Contradiction:
Improvelight outputVSAvoidassembly process
Core Design Contradiction:
Illumination intensityVSEase of manufacture

Solution Approach 1:

The lighting assembly is designed as a separate, modular component that can be manufactured independently and then integrated into the bath caddy tray. This segmentation allows the lighting subsystem to be produced using standardized LED components and assembly processes, reducing the overall manufacturing complexity while still providing integrated illumination functionality.

Inventive Principle:
Principle #1Segmentation
