Solution Overview

Problem

Conventional dryers with drying functions struggle to efficiently dry heavy objects due to the generation of loud noise and potential machine malfunction caused by the impact of heavy objects on the drum during the drying process.

Innovation Solution

A dryer rack with a platform and grip system designed for easy attachment and stable loading into the drum, featuring a lattice structure, rotatable supports, and asymmetrically arranged grips for secure handling and positioning, which prevents the rack from rotating and falling during operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If heavy objects are dried using conventional lifters in a drum, then drying function is achieved, but loud noise and potential machine malfunction occur due to impact shock

Engineering Contradiction:
Improvedrying capabilityVSAvoidnoise and shock
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The dryer rack acts as an intermediary structure between the heavy drying object and the drum. It provides a dedicated platform that supports the object's weight and controls its movement, preventing direct impact on the drum while still enabling effective drying through the rack's design that allows hot air circulation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a dryer rack is designed for stable loading in the drum, then drying stability is improved, but attachment complexity increases

Engineering Contradiction:
Improveloading stabilityVSAvoidattachment structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The attachment structure is segmented into multiple independent components: front support with first lower surface, rear support with second lower surface, and grip elements. Each segment performs a specific function (support, positioning, or handling), allowing the overall system to achieve high stability through simple, modular attachments rather than a complex integrated structure.

Inventive Principle:
Principle #1Segmentation

AI summary

A dryer rack for use with an apparatus for drying an object inside a drum is disclosed, wherein the dryer rack includes a platform for having an upper surface for supporting the object. The platform may include at least one grip for loading and unloading the dryer rack into an interior space of the drum. The at least one grip is flush with the upper surface of the platform. The at least one grip is formed in a forward portion of the platform, to be near an access point of the drum.
