Problem

Existing packaging methods for large household appliances, such as foamed components, biodegradable chips, and honeycomb panels, face inefficiencies in securing and cushioning, time consumption, and waste generation, particularly when dealing with complex shapes and heavy appliances.

Innovation Solution

A combination tool with a compression and cutting operator integrated in a single shaft, allowing simultaneous processing of layered pulp structures like corrugated cardboard or honeycomb panels, ensuring precise geometry and reduced processing time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If multiple honeycomb panels are layered and joined after processing to achieve complex shapes, then the packaging capability for heavy household appliances is improved, but the device complexity, handling requirements, labor, and costs increase significantly

Engineering Contradiction:
Improvepackaging capabilityVSAvoidprocessing complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent combines multiple processing functions (cutting, shaping, compression) into a single combination tool that can process multiple honeycomb panels simultaneously in one operation, eliminating the need for sequential processing and joining of separate panels. This merging of functions directly reduces device complexity and processing steps while maintaining the ability to create complex packaged shapes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The combination tool is designed with multiple operators that perform different functions (cutting, shaping, compression) within a single tool body, making it a universal tool capable of handling various processing requirements for thick layered pulp structures in one operation, thereby reducing the need for multiple specialized tools and processing steps.

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

2Manufacturing precision

If sequential processing with different tools is used for layered pulp structures, then each processing step can be optimized, but positioning errors occur and processing time increases

Engineering Contradiction:
Improveprocessing precisionVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

By merging cutting, shaping, and compression operations into a single combination tool that processes all layers simultaneously, the patent eliminates the need for multiple sequential tool operations. This prevents positioning errors between steps and dramatically reduces total processing time while maintaining precision through coordinated multi-operator action.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The combination tool performs cutting, shaping, and compression operations in continuous sequence within a single processing pass, ensuring that each operator acts on the material immediately after the previous operation without interruption or repositioning. This continuous action eliminates idle time and positioning errors between discrete processing steps.

Inventive Principle:
Principle #20Continuity of useful action

3Strength

If foamed components are used for packaging large household appliances, then cushioning and securing capability is improved, but the processing time for foaming and curing increases significantly

Engineering Contradiction:
Improvecushioning capabilityVSAvoidprocessing time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The patent uses pre-formed honeycomb panels made from recyclable pulp material as disposable packaging components that provide adequate cushioning and securing capability without requiring time-consuming foaming or curing processes. These panels can be quickly processed and assembled, offering a time-efficient alternative to foam while maintaining protective functionality.

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

4Manufacturing precision

If conventional cutting and compression operations are performed separately on thick layered pulp structures, then each operation can be optimized, but the overall processing efficiency decreases

Engineering Contradiction:
Improveoperation optimizationVSAvoidprocessing efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent merges conventional cutting and compression operations into a single combination tool where multiple operators work simultaneously on thick layered pulp structures. This allows the structural integrity to be maintained through coordinated action while dramatically improving processing efficiency by eliminating the need for separate processing steps.

Inventive Principle:
Principle #5Merging (Combining)
