Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If rigid collection containers are used, then the structure is stable and durable, but frequent assembly and disassembly are required leading to operational inefficiency

Engineering Contradiction:
Improveoperational efficiencyVSAvoidassembly and disassembly frequency
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent employs disposable flexible collection containers (such as plastic bags) that can be easily filled, sealed, and replaced without disassembly. Once full, the entire container is discarded and replaced with a new one, eliminating the need for frequent cleaning and reassembly operations.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent uses flexible thin-film containers (plastic bags or similar materials) instead of rigid containers. These flexible containers can be easily inserted into and removed from the dust collection chamber, requiring minimal manipulation and no complex assembly procedures.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of manufacture

If specialized rigid collection containers are manufactured, then the containers are durable and reusable, but operating costs increase due to the need for specialized containers

Engineering Contradiction:
Improvecontainer manufacturing complexityVSAvoidoperating costs
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The mounting device is designed with universal compatibility to accept various types of flexible containers including plastic bags, shopping bags, and other commonly available flexible materials. This universality eliminates the need to manufacture specialized rigid containers, reducing both manufacturing complexity and operating costs.

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

Solution Approach 2:

Instead of manufacturing expensive specialized rigid containers, the patent utilizes inexpensive disposable flexible containers that can be obtained from common sources, significantly reducing operating costs while eliminating the need for complex container manufacturing processes.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Adaptability or versatility

If rigid collection containers are used, then the containers provide structural stability, but user flexibility is reduced due to the need for frequent maintenance

Engineering Contradiction:
Improveuser flexibilityVSAvoidmaintenance frequency
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent employs disposable flexible containers that eliminate maintenance activities such as cleaning, drying, and reassembly. Users simply replace full containers with empty ones, providing maximum flexibility and eliminating the operational constraints imposed by rigid container maintenance requirements.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
