Solution Overview

Problem

Existing clothing care devices suffer from instability, noise, and reduced service life due to quick return phenomena and failure of elastic reset mechanisms in their crank and cam mechanisms, leading to poor user experience and ineffective wrinkle removal.

Innovation Solution

A clothing shaking device with a cross beam, driven by a motor, uses a cam and sliding member with a receiving groove to achieve stable reciprocating motion, guided by guide members, eliminating the need for elastic reset mechanisms and reducing weight through a hollow cam design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If clothes are left in a damp state after washing, then energy consumption is reduced, but hygiene performance deteriorates due to bacterial growth and odors

Engineering Contradiction:
Improveenergy consumptionVSAvoidhygiene performance
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The clothes dryer allows clothes to dry naturally without energy consumption, while the optional ultraviolet sterilization module provides hygiene treatment only when needed. The system serves itself by using the natural drying process as the primary function, eliminating the need for continuous energy input while maintaining hygiene through periodic or on-demand sterilization.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The ultraviolet sterilization module is extracted as an optional separate function from the basic drying process. This allows the system to maintain low energy consumption for the core drying function while providing hygiene performance through a detachable, on-demand sterilization component that can be activated based on user needs or environmental conditions.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a clothes dryer with ultraviolet sterilization module is used, then hygiene performance is improved, but device complexity increases

Engineering Contradiction:
Improvehygiene performanceVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The ultraviolet sterilization module is designed to be universally applicable to different types of clothes dryers without requiring fundamental changes to the base structure. The module can be integrated into various drying system configurations, providing enhanced hygiene functionality while maintaining compatibility with existing dryer designs, thereby limiting the increase in device complexity.

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

3Productivity

If clothes are shaken at high speed, then drying efficiency is improved, but clothes may become tangled or damaged

Engineering Contradiction:
Improvedrying efficiencyVSAvoidclothes integrity
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The shaking mechanism operates with dynamically adjusted parameters, allowing the system to optimize between drying efficiency and clothes protection. The shaking speed, amplitude, and duration can be varied based on fabric type and drying stage, enabling high-speed shaking for robust items while using gentler cycles for delicate garments, thus maintaining clothes integrity while achieving effective drying.

Inventive Principle:
Principle #15Dynamics

AI summary

The present invention relates to the technical field of clothes care, and specifically provides a clothes shaking apparatus and a clothes care device comprising same. The clothes shaking apparatus comprises a cross beam, a drive member, a cam, a sliding member, and a guide member. The cross beam, the drive member and the guide member are connected to a box body of a care device, an accommodating slot matching the cam is formed on the sliding member. When the drive member drives the cam to rotate, the sliding member is driven to reciprocate, and meanwhile, the cross beam is driven to reciprocate, so that clothes hung on the cross beam can shake to remove wrinkles. Moreover, in the reciprocating process of the sliding member, the guide member can guide the sliding member, so that the sliding member moves in a straight line. In this way, under the drive of the cam, the sliding member reciprocates in a straight line, and meanwhile drives the cross beam to reciprocate. By means of such setting, a clothes hanger provided on the cross beam can be prevented from striking a back plate of the box body or a front door body of the box body.
