Solution Overview

Problem

Home appliance chillers face issues with protection against debris and condensed water, which can cause corrosion and jamming, and pose safety risks due to exposed guiding elements that can entrap users' limbs.

Innovation Solution

A telescopic guiding unit that converts between fully contracted and fully extracted states, combined with a cover unit that mostly covers the stationary guiding element in the fully extracted state, providing protection and improved safety by hiding the guiding element from view and preventing debris and water ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the telescopic guiding unit is left exposed for functionality, then ease of operation is improved, but protection against debris and condensed water deteriorates

Engineering Contradiction:

Improveease of operationVSAvoidprotection against debris and condensed water

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A cover element is introduced as an intermediary component that bridges the conflict between operational accessibility and protection. The cover element can be moved between covering and uncoved positions, allowing the guiding unit to be protected when not in use while remaining accessible when needed for operation

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the stationary guiding element is exposed, then ease of operation is improved, but safety deteriorates due to entrapment risk

Engineering Contradiction:

Improveease of operationVSAvoidoperational safety

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The cover element serves as a safety intermediary that physically barriers users from the guiding unit when not in use, eliminating entrapment risks while maintaining operational accessibility when the cover is moved to the uncoved position

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If the guiding unit is covered, then protection against debris and condensed water is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveprotection against debris and condensed waterVSAvoidease of operation

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The cover element is designed with dynamic movement capability, allowing it to transition between covering and uncoved positions. This dynamic design ensures the cover provides protection during storage while being easily movable to allow operation when needed

Inventive Principle:

Principle #15Dynamics
