Innovation Solution

Integrating display and operating elements within a gap-free housing of the blower filter device, allowing for a seamless and integrated design that simplifies reprocessing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If display elements and operating elements are mounted on the housing with openings, then the device is easy to operate and display, but the housing has gaps and cavities that make reprocessing difficult

Engineering Contradiction:
Improveoperation and display functionalityVSAvoidreprocessing ease
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent integrates display elements and operating elements directly into the housing structure, eliminating separate mounting openings. The housing itself becomes part of the display/operating element assembly, creating a seamless integrated structure that is both functional and easy to reprocess.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The display and operating elements are nested within the housing structure rather than being mounted on it. This nesting approach allows the elements to be embedded in the housing material itself, eliminating external openings while maintaining full functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If the housing has openings for display and operating elements, then the elements are accessible, but cleaning and maintenance become more difficult due to gaps and cavities

Engineering Contradiction:
Improveelement accessibilityVSAvoidcleaning and maintenance ease
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

By merging the display and operating elements with the housing structure, the patent eliminates gaps and cavities that would otherwise trap contaminants. The integrated design ensures that surfaces are continuous and accessible for thorough cleaning without hidden corners or mounting holes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The housing and integrated elements form a homogeneous structure with uniform material composition and continuous surfaces. This homogeneity eliminates the heterogeneity of separate components with mounting openings, making the entire surface equally accessible for cleaning and maintenance.

Inventive Principle:
Principle #33Homogeneity

3Ease of manufacture

If display and operating elements are integrated without openings, then reprocessability is improved, but the complexity of integration increases

Engineering Contradiction:
ImprovereprocessabilityVSAvoidintegration complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent segments the housing into functional zones where display and operating elements are integrated during the molding process. This segmentation allows complex integrated features to be created through standardized mold design techniques, managing complexity through modular tooling approaches.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent utilizes changes in material parameters during the molding process, such as varying material flow characteristics or curing properties, to enable integration of display and operating elements. By controlling material parameters, the complex integration is achieved through material behavior rather than complex mechanical assembly.

Inventive Principle:
Principle #35Parameter changes
