Solution Overview

Problem

Existing toy building block washing methods are cumbersome, time-consuming, and lack durable, dishwasher-safe solutions that allow for easy washing and drying without requiring users to touch the contents.

Innovation Solution

A washable and stackable sifter bin system comprising a circular bottom sheet with holes, a cylindrical wall, and a central knob, allowing for hands-free washing and drying by stacking and spinning the bins to separate and drain water, with features like drainage and drying holes, and a locking mechanism for secure handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional wooden sifters are used for toy building blocks, then the device is easily breakable and has low durability, but switching to more durable materials would prevent washing the contents

Engineering Contradiction:

ImprovedurabilityVSAvoidability to wash contents

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The sifter is divided into separate components: a removable sifter top with holes and a container body. This segmentation allows the sifter top to be detached for washing contents while maintaining the structural integrity and durability of the overall device.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A removable sifter top acts as an intermediary component between the user and the contents. It provides the washing function by being detachable, while the main container body maintains durability and can withstand dishwasher cleaning.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If toy building blocks are soaked in soapy water manually, then washing is possible, but the process is cumbersome and time consuming

Engineering Contradiction:

Improvewashing convenienceVSAvoidwashing time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The sifter bin is designed to be self-service capable by being fully dishwasher safe. The components can be easily placed in the dishwasher without manual scrubbing or prolonged soaking, allowing the washing machine to do the work automatically and reducing both effort and time.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The material parameters of the sifter bin are changed to be dishwasher safe (heat resistant and durable). This allows the washing process to use higher temperatures and stronger water jets in the dishwasher, significantly reducing washing time compared to gentle manual soaking.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If toy building blocks are washed manually with soapy water, then washing is achieved, but drying takes additional time and effort

Engineering Contradiction:

Improvedrying convenienceVSAvoiddrying time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The sifter bin enables self-service drying by allowing blocks to drain and air-dry automatically after dishwasher washing. The design facilitates easy removal of blocks for drying or leaving them to drain in the sifter, eliminating the need for manual towel drying.

Inventive Principle:

Principle #25Self-service

4Weight of moving object

If smaller metal containers are used for toy building blocks, then portability is improved, but durability and ability to wash large quantities are reduced

Engineering Contradiction:

ImproveportabilityVSAvoiddurability and washing capacity

Core Design Contradiction:

Weight of moving objectVSReliability

Solution Approach 1:

The sifter top nests within the container body, and multiple sifters can be stacked together. This nesting design maintains a compact, portable form factor while the larger container body provides sufficient capacity for washing large quantities of blocks. The nested structure does not compromise durability as both components are made from robust, dishwasher-safe materials.

Inventive Principle:

Principle #7Nested doll (Nesting)
