Solution Overview

Problem

Existing silverware containers for dishwashers face a dilemma between being too small, which is inconvenient for loading/unloading, and too large, which wastes space, as they need to accommodate varying quantities of silverware during washing.

Innovation Solution

A silverware container with telescopable horizontal segments that can be adapted to fit different sizes, allowing flexible use and easy loading/unloading, and incorporating guiding means for secure attachment to the dishwasher basket, with features like slots and mesh holes for improved rinsing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the silverware tray is made large to accommodate more silverware, then the quantity of silverware that can be washed increases, but the tray covers a large part of the basket top and makes loading/unloading difficult

Engineering Contradiction:
Improvequantity of silverwareVSAvoidloading/unloading convenience
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The silverware container is divided into multiple segments (first segment, second segment, third segment) that can be independently positioned along the longitudinal axis. This segmentation allows the container to be adjusted to different lengths, enabling users to optimize between capacity and accessibility based on their specific needs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The container transitions from a static structure to a dynamic one with adjustable segments. The segments can be moved relative to each other along the longitudinal axis, allowing the container length to be adapted. This dynamic adjustment resolves the contradiction by enabling the container to be long when maximum capacity is needed and short when ease of loading/unloading is prioritized.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the silverware tray is made small to facilitate frequent moving for loading/unloading, then ease of operation improves, but the quantity of silverware that can be washed decreases

Engineering Contradiction:
Improveloading/unloading convenienceVSAvoidquantity of silverware
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The container is segmented into movable sections that can be independently positioned. Users can configure the segments to create a shorter container for easier handling or extend them for increased capacity, depending on the situation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adjustable segment mechanism enables the container to dynamically adapt its length. When ease of operation is the priority, the container can be configured in a compact form. When maximum capacity is needed, the segments are extended, thus resolving the trade-off between size and operability.

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If the silverware container area is reduced to maximize space for other items, then space utilization improves, but the capacity for silverware decreases

Engineering Contradiction:
Improveavailable space in basketVSAvoidsilverware capacity
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The segmented design allows the container to be configured in different lengths, enabling users to minimize its footprint when silverware capacity is not the priority, thereby maximizing space for other items in the basket.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dynamic adjustability of the container length allows it to be compact when needed to preserve basket space, and extended when maximum silverware capacity is required. This resolves the contradiction between space utilization and capacity by allowing context-dependent configuration.

Inventive Principle:
Principle #15Dynamics
