Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two separate heating tubes are used for dual voltage compatibility, then voltage adaptability is improved, but device complexity and volume increase

Engineering Contradiction:
Improvevoltage compatibilityVSAvoidinternal connections
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges two separate heating tubes into a single integrated heating tube with dual-layer structure. The heating tube includes a first heating section for 100-120V and a second heating section for 220-240V, connected through connecting sections. This integration eliminates the need for separate tubes and reduces internal connection complexity while maintaining dual voltage compatibility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single integrated heating tube serves multiple functions by incorporating different heating sections that can operate with different voltage inputs. The first heating section activates at 100-120V while the second heating section activates at 220-240V, allowing one component to perform the work of what would traditionally require two separate components.

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

2Adaptability or versatility

If two separate heating tubes are used, then voltage compatibility is achieved, but equipment volume increases

Engineering Contradiction:
Improvevoltage compatibilityVSAvoidequipment volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent merges two separate heating tubes into a single integrated heating tube with dual-layer structure. The heating tube includes a first heating section for 100-120V and a second heating section for 220-240V, connected through connecting sections. This integration eliminates the need for separate tubes and reduces internal connection complexity while maintaining dual voltage compatibility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The heating tube employs a nested dual-layer structure where the first heating section and second heating section are arranged in concentric or stacked configurations. This nesting allows both heating sections to occupy overlapping or adjacent spatial zones, significantly reducing the overall volume compared to two separate tubes.

AI summary

The present invention belongs to the technical field of electrical appliances, especially relates to a heating unit, a heating inner chamber and a hanging ironing machine, wherein the heating unit comprises an integrated heating tube, the integrated heating tube is in a continuous and double-layers stacked shape, and a single-layer structure of the integrated heating tube is configured to include at least two sections of straight tubes that extend along a length direction. Through reasonable spatial structure, a total length of a single tube is increased as much as possible in the range of small space, thereby increasing the maximum power of the whole heating tube, thus to prevent damage and safety hazards caused by excessive currents and powers due to unstable control voltages.
