Solution Overview

Problem

The existing laundry dryers face challenges in efficiently positioning nozzles and attachment means on the frame due to space constraints, leading to issues like fluid blockage, increased labor, and production complexities when dealing with delicate items and deformable articles.

Innovation Solution

A support structure on the frame surrounding the loading opening that integrates both the nozzle and attachment means, allowing for efficient fluid distribution and basket stabilization without requiring additional space, with features like separate nozzle and attachment placement on opposite surfaces, a conduit system through a tube, and a chamber for fluid collection, ensuring proper positioning and easy mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate nozzles and attachment means are provided on the frame, then fluid spraying function is improved, but device complexity and space requirements increase

Engineering Contradiction:

Improvefluid spraying functionVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the nozzle and attachment means into a single integrated support structure. The support includes both the attachment means for holding the basket and the nozzle for fluid spraying, eliminating the need for separate components and reducing overall device complexity while maintaining both functions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The support structure serves multiple functions simultaneously: it acts as both the attachment means for securing the basket to the frame and as the mounting structure for the nozzle. This multi-functional design reduces the number of separate components needed in the system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If additional nozzles and attachment means are added on the frame, then fluid distribution coverage is improved, but mounting labor and production time increase

Engineering Contradiction:

Improvefluid distribution coverageVSAvoidmounting labor and production time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

By integrating the nozzle and attachment means into one support structure, the patent reduces the number of separate mounting operations required. Instead of separately mounting nozzles and attachment means, the integrated support is mounted as a single unit, significantly reducing mounting labor and production time.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If more nozzles and attachment means are mounted on the frame, then fluid spraying capability is improved, but molding and production difficulty increase

Engineering Contradiction:

Improvefluid spraying capabilityVSAvoidmolding and production

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The integration of nozzle and attachment means into a single support structure simplifies the molding process. Instead of requiring separate molds and assembly steps for multiple components, the integrated design can be produced as a single molded part, significantly easing manufacturing and production.

Inventive Principle:

Principle #5Merging (Combining)

4Area of stationary object

If nozzle and attachment means are positioned close to each other on the frame, then space utilization is improved, but fluid flow blockage may occur

Engineering Contradiction:

Improvespace utilizationVSAvoidfluid flow blockage

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent positions the nozzle and attachment means on different surfaces of the support structure rather than on the same plane. This spatial arrangement in three dimensions allows close proximity for space efficiency while preventing fluid flow blockage by directing the spray away from the attachment means.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
