Solution Overview

Problem

Existing fixing devices for transport rods in laundry care appliances are prone to being lost or forgotten after transport, as they are not permanently attached to the appliance.

Innovation Solution

A fixing device that is permanently connected to the laundry care appliance, featuring a fixing element and a closing surface device, allowing for secure attachment and closure of the transport rod, with options for rotary or pivoting movement to transition between fixing and locking positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a transport plug is used to secure a transport rod in an opening of the laundry care device, then the transport rod can be fixed during transport, but the fixing device can be lost or forgotten after transport since it is not permanently attached to the laundry care device

Engineering Contradiction:
Improvefixing device retentionVSAvoidfixing device structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the fixing device with the laundry care device by permanently attaching it to a component such as the rear wall. This merging ensures the fixing device cannot be lost while maintaining a relatively simple structure through integration rather than separate components

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fixing device is designed to perform multiple functions: fixing the transport rod during transport, closing the opening after transport, and preventing loss by permanent attachment. This multi-functionality resolves the contradiction by achieving reliable retention without proportionally increasing complexity

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

2Ease of operation

If the opening is left open after transport for access, then ease of operation is improved, but child safety and splash water tightness are compromised

Engineering Contradiction:
Improveopening accessVSAvoidchild safety and water ingress
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The fixing device is designed to be movable between different positions (open and closed states). This dynamic capability allows the opening to be accessible when needed while providing the ability to close and secure it for safety and protection, resolving the contradiction between ease of operation and harmful factor prevention

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If a transport rod is inserted into an opening for structural support during transport, then stability is improved, but the opening requires a fixing device that may be lost

Engineering Contradiction:
Improvetransport stabilityVSAvoidfixing device retention
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The fixing device is pre-installed and permanently attached to the laundry care device before transport. This preliminary action ensures the fixing device is already in position and cannot be lost during or after transport, while still allowing the transport rod to be securely inserted and fixed when needed

Inventive Principle:
Principle #10Preliminary action
