Solution Overview

Problem

Rechargeable dehumidifiers with complex cavity configurations for anchoring and sealing lead to aesthetic and manufacturing challenges due to surface discontinuities and the need for intricate designs.

Innovation Solution

A rechargeable dehumidifier design featuring a casing with a top opening and a nested vessel with a second lid for desiccant placement, allowing internal components to be arranged without external projections, enabling a minimalist appearance and simplified manufacturing with straight, smooth surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex cavity configurations with lips and burrs are used for anchoring and sealing, then stability and sealing are improved, but aesthetic appearance and manufacturing simplicity deteriorate

Engineering Contradiction:
Improvestability and sealingVSAvoidcavity configuration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies nesting by placing the second cavity (vessel) inside the first cavity (basin), and the third cavity (lid) on top of the second cavity. This nested arrangement allows anchoring and sealing features to be located internally rather than on external surfaces, eliminating the need for complex external lips and burrs while maintaining stability and sealing functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent moves the anchoring and sealing functionality from the external horizontal dimension (lips and burrs on cavity surfaces) to the internal vertical dimension (features within the nested cavities). This dimensional shift allows the external surfaces to remain smooth and simple while the internal structure provides the necessary mechanical interlocking and sealing.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If complex surface configurations are used for anchoring, then stable assembly is improved, but manufacturing ease deteriorates

Engineering Contradiction:
Improveassembly stabilityVSAvoidmanufacturing simplicity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By nesting the vessel inside the basin and placing the lid on the vessel, the patent creates a hierarchical structure where anchoring features can be integrated into the nested interfaces rather than requiring complex surface machining. This simplifies manufacturing as each component can be formed more simply and assembled through the nested arrangement.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent divides the dehumidifier into separate nested components (basin, vessel, lid) that can be manufactured independently with simpler geometries. The anchoring and sealing functions are distributed across the interfaces between these segmented parts rather than requiring complex monolithic surface configurations.

Inventive Principle:
Principle #1Segmentation

3Reliability

If protruding anchoring features are used, then stable connection is improved, but aesthetic appearance deteriorates

Engineering Contradiction:
Improveconnection stabilityVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The nested cavity structure allows all anchoring features (lips, burrs, interlocking elements) to be positioned internally within the device. The external surfaces of the basin, vessel, and lid can therefore be designed as smooth, continuous surfaces without protruding features, achieving both aesthetic appeal and connection stability.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent extracts the anchoring and sealing features from the external surface domain and relocates them to the internal domain. This separation allows the external aesthetic surfaces to remain clean and uninterrupted while the internal structure provides the necessary mechanical connection stability.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Rechargeable dehumidifier including inside it the components it consists of, with the possibility that none of them project outward so that it can have an outward appearance without projections, as well as being simple to manufacture, comprising a casing with at least one first opening and open on the top, which configures a first internal cavity, a first lid arranged on top of the casing, provided in the first cavity with a container that in turn comprises a body open on the top that configures a second cavity, a second lid provided on top of the body and having at least one second opening; on top of the second lid may be provided a desiccant agent such that the water absorbed by it is collected in the body when it falls by gravity.
