Solution Overview

Problem

Existing heated clothes racks or stands are bulky, inconvenient for transportation and storage, and require separate delivery to the consumer, violating CE and GS marking requirements due to proximity of heating elements to users.

Innovation Solution

A compact foldable drying apparatus with rotatable and slidable elongate segments that enclose electrical heating elements, allowing for a compact storage state and easy assembly into an operational drying position, with protected electrical conductors to meet safety standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If heated clothes racks are made collapsible to reduce storage volume, then storage and transportation convenience is improved, but the structure becomes more complex and delivery logistics remain problematic

Engineering Contradiction:
Improvestorage volumeVSAvoidstructural complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The support frame is divided into multiple elongate segments that can be collapsed relative to each other, reducing the overall volume of the device for storage and transportation while maintaining structural integrity during use

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The arm assemblies are designed to nest within or alongside the support frame segments when collapsed, maximizing space utilization and minimizing the overall footprint during storage and shipping

Inventive Principle:
Principle #7Nested doll (Nesting)

2Use of energy by moving object

If heating elements are placed close to users for effective warming, then heating efficiency is improved, but safety compliance becomes difficult to achieve

Engineering Contradiction:
Improveheating efficiencyVSAvoidsafety compliance
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

Protective barriers or enclosures are introduced as intermediary elements between the heating elements and users, allowing the heating elements to remain positioned for effective warming while preventing direct contact or excessive heat exposure to users

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Heat-resistant protective coatings or thin film barriers are applied to components that may come into contact with users, providing thermal protection while maintaining the heating efficiency of the underlying elements

Inventive Principle:
Principle #30Flexible shells and thin films

3Device complexity

If electrical conductors are exposed during folding for simplicity, then manufacturing complexity is reduced, but safety and reliability deteriorate due to conductor abrasion

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidconductor integrity
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

Flexible protective sheaths or conduits are used to enclose the electrical conductors along the folding joints, preventing abrasion and damage during repeated folding and unfolding cycles while maintaining electrical connectivity

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

Protective coverings are pre-installed on conductors before assembly, providing advance protection against mechanical damage that would occur during normal folding operations

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
