Solution Overview

Problem

Existing packaging technologies face challenges in efficiently packaging objects with irregular shapes, leading to increased production costs, operational difficulties, and potential moisture-related safety hazards, especially for marine and precision instrument products.

Innovation Solution

A packaging apparatus comprising multiple base plates and elastic sheets, where the elastic sheets are physically connected to the base plates to cover openings and immobilize objects, allowing for flexible adaptation to irregular shapes and providing moisture resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional packaging structures are used for irregularly shaped objects, then packaging simplicity is maintained, but packaging effectiveness and protection capability deteriorate

Engineering Contradiction:

Improveadaptability to irregular shapesVSAvoidpackaging structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses elastic sheets as flexible wrapping elements that can conform to irregular object shapes. These thin film structures provide adaptation to various geometries without requiring complex rigid packaging frameworks, thereby resolving the contradiction between adaptability and structural complexity.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The packaging apparatus incorporates movable and adjustable components including elastic sheets that can be stretched and positioned dynamically. This dynamic flexibility allows the same packaging structure to adapt to different irregular shapes while maintaining relatively simple overall construction.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If custom packaging structures are designed for different product shapes, then packaging effectiveness improves, but production cost increases

Engineering Contradiction:

Improveproduct shape adaptabilityVSAvoidproduction cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The packaging apparatus is designed as a universal device that can accommodate multiple product shapes using the same basic structure of base plates and elastic sheets. The elastic sheets serve multiple functions including wrapping, securing, and protecting different shaped objects, thereby reducing the need for multiple custom-designed packaging solutions and lowering production costs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent utilizes elastic sheets whose physical parameters (elasticity, stretchability) can be adjusted to accommodate different product shapes. By changing the physical state and mechanical properties of the elastic material rather than redesigning the entire packaging structure, the system achieves shape adaptability while maintaining manufacturing simplicity.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If rigid packaging structures are used for protection, then protection capability improves, but adaptability to irregular shapes deteriorates

Engineering Contradiction:

Improveprotection capabilityVSAvoidshape flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The packaging system combines rigid base plates providing structural support and protection with flexible elastic sheets that conform to irregular shapes. This composite structure integrates the advantages of both rigid and flexible materials, achieving reliable protection capability while maintaining adaptability to various product geometries.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent merges the protective function of rigid structures with the adaptive wrapping function of flexible elastic sheets in a unified packaging system. The base plates and elastic sheets work together synergistically, where the rigid components provide protection and the flexible components provide shape adaptation, resolving the contradiction between protection capability and shape flexibility.

Inventive Principle:

Principle #5Merging (Combining)
