Solution Overview

Problem

Refrigerator dispensers face challenges in accommodating vessels of various sizes and efficiently removing remaining water or ice, with complex assembly processes that can damage components.

Innovation Solution

A dispenser assembly with a tray assembly that is drawably connected to the dispenser, featuring a tray body with a remaining water storage and a tray cover for easy drainage, and a guide member for simplified assembly and protection against damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the tray assembly is rigidly attached to the dispenser assembly, then the structure is stable, but it cannot be removed for cleaning and maintenance

Engineering Contradiction:
Improveease of cleaningVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The tray assembly is segmented from the dispenser assembly through a detachable connection mechanism. The tray assembly includes a tray body and tray cover that can be separated from the dispenser assembly, allowing easy removal for cleaning while maintaining structural stability when connected. The guide member and engagement structure enable the tray to be divided into removable and fixed portions.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the dispenser assembly uses a complex engagement structure for attachment, then the connection is secure, but the assembly process becomes complicated and components may be damaged

Engineering Contradiction:
Improveconnection reliabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A guide member serves as an intermediary element between the tray assembly and dispenser assembly. The guide member includes a guide rib that fits into a guide slit, facilitating easy alignment and connection while preventing misalignment damage. This intermediary structure simplifies the engagement process and ensures reliable connection without requiring complex assembly procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the tray assembly is designed to accommodate vessels of various sizes, then the versatility is improved, but the structural complexity increases

Engineering Contradiction:
Improvevessel size adaptabilityVSAvoidtray structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The tray assembly incorporates a rotatable tray that can be rotated to different positions and angles. This dynamic feature allows the tray to adapt to vessels of various sizes and shapes by adjusting its orientation, providing versatility without requiring multiple fixed-configuration trays. The rotatable mechanism simplifies the overall structure compared to having multiple specialized trays.

Inventive Principle:
Principle #15Dynamics
