Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing blower filter devices are difficult to reprocess due to gaps and cavities that form around display and control elements, which hinder effective cleaning and maintenance.

Innovation Solution

Integrating display and control elements within a gap-free housing, along with an energy storage unit and interface, to enhance reprocessability by eliminating openings and cavities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If display and control elements are integrated into the housing without an opening, then reprocessability is improved, but device complexity increases

Engineering Contradiction:

ImprovereprocessabilityVSAvoiddevice complexity

Core Design Contradiction:

Ease of repairVSDevice complexity

Solution Approach 1:

The display element and control element are merged with the housing structure, eliminating the need for separate openings or cavities. The housing itself serves as the mounting structure, integrating multiple functions into a single component to improve reprocessability while managing complexity through functional consolidation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The housing is designed to serve multiple functions: it provides structural support, houses the display element, accommodates the control element, and eliminates the need for separate openings. This multi-functionality reduces the number of components and simplifies the overall structure for better reprocessability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of manufacture

If display and control elements are integrated into the housing without an opening, then cleaning is simplified, but manufacturing precision requirements increase

Engineering Contradiction:

Improvecleaning easeVSAvoidmanufacturing precision

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

By merging the display and control elements with the housing structure, the patent eliminates gaps and cavities that would otherwise require precise sealing. The integrated structure allows for simpler cleaning access while the manufacturing precision is managed through the unified design that eliminates the need for separate precision-fit openings.

Inventive Principle:

Principle #5Merging (Combining)

3Object-affected harmful factors

If display and control elements are integrated into the housing without an opening, then contamination is prevented, but ease of operation may be affected

Engineering Contradiction:

Improvecontamination preventionVSAvoidease of operation

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The display and control elements are merged with the housing to eliminate openings that could allow contamination. The control element can still be operated through the integrated housing structure, maintaining ease of operation while preventing contamination through the closed design.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces mechanical openings with an integrated housing structure that provides protection. The control element operates through this integrated structure without requiring physical openings, substituting a mechanical opening-based system with a housing-integrated system that prevents contamination while maintaining operability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
