Solution Overview

Problem

Existing packaging boxes for block-shaped products are inconvenient for consumers who want to access and consume multiple types of products with different flavors, as they often require multiple purchases and are difficult to handle and control with one hand, especially in scenarios like driving.

Innovation Solution

A packaging box design with internal spacers dividing the space into multiple cavities, featuring flip covers for easy access and guide rails for product guidance, allowing various types of blocks to be stored and easily accessed with one hand.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a packaging box is configured with a single cavity and a single outlet, then the structure is simple, but consumers cannot access multiple types of products with different flavors without purchasing multiple boxes

Engineering Contradiction:
Improveability to accommodate multiple product typesVSAvoidpackaging box structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The packaging box is divided into multiple independent cavities (first cavity, second cavity, etc.) separated by spacers, allowing different product types to be stored in separate compartments. Each cavity has its own outlet, enabling consumers to access different products without opening the entire box, thus resolving the contradiction between versatility and structure complexity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a packaging box has multiple cavities for different products, then consumers can access multiple product types, but the structure becomes more complex

Engineering Contradiction:
Improveproduct variety accommodationVSAvoidinternal packaging structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spacers serve multiple functions: they divide the internal space into separate cavities, provides structural support for the box, and help maintain the shape of each cavity. This multi-functionality reduces the need for additional complex structures while achieving the goal of accommodating multiple product types.

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

3Ease of operation

If consumers need to access products from a packaging box, then they can consume the products, but it is difficult to control the number of products accessed at a time and requires two hands

Engineering Contradiction:
Improveone-hand operation capabilityVSAvoidaccess mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The outlets are designed with movable flaps that can be opened and closed dynamically. When a product is accessed, the flap opens to allow the product to be removed, then automatically closes to control the number of products accessed. This dynamic mechanism enables one-hand operation while maintaining control over product access.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If the packaging box is designed for easy one-hand access, then consumers can operate it conveniently, but the structure may become more complex

Engineering Contradiction:
Improveone-hand access easeVSAvoidcover and outlet mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cover structure is merged with the outlet mechanisms, where the cover itself incorporates the flaps that control product access. This integration eliminates the need for separate complex mechanisms, allowing one-hand operation while keeping the overall structure relatively simple.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present utility model relates to a packaging box. The packaging box includes: an upper cover; and a lower cover. The upper cover and the lower cover can be combined together to form an internal packaging space therebetween. The packaging box further includes at least one spacer provided in the interior of at least one of the upper cover and the lower cover. When the upper cover and the lower cover are combined, the spacer divides the internal packaging space into at least a left cavity and a right cavity. The left cavity and the right cavity have a left outlet and a right outlet, respectively, and at least one of the upper cover and the lower cover is provided with at least one flip cover. The at least one flip cover can be flipped vertically to close or open the left outlet and/or the right outlet. In the present utility model, various types of blocks can be stored in one packaging box and easily accessed by a consumer with one hand, thereby greatly improving user experience of the consumer.
