Solution Overview

Problem

Conventional containers used for shipping supplies are often discarded after use, leading to waste and high transportation costs, and existing construction materials are expensive and impractical for immediate shelter needs in disaster or hostile areas, where there is a lack of water, food, and building structures.

Innovation Solution

A hollow HDPE plastic construction block designed for storing water or other items, which can be filled with sand or dirt to provide structural integrity, allowing for stacking, interlocking, and reuse as a building block for bunkers, walls, or shelters, capable of withstanding kinetic energy and supporting loads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If conventional containers are used for shipping supplies, then supplies can be transported, but the containers are discarded after use leading to waste and high transportation costs

Engineering Contradiction:
Improvewaste packagingVSAvoidcontainer reuse
Core Design Contradiction:
Loss of substanceVSAdaptability or versatility

Solution Approach 1:

The patent applies the discarding and recovering principle by designing containers that can be recovered and reused as construction blocks after their initial use for shipping supplies. The container structure is designed to maintain integrity and functionality for both shipping and construction purposes, eliminating the need to discard the container after single use.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The patent implements universality by creating a multi-functional container that serves dual purposes: first as a shipping container for transporting supplies, and second as a construction block for building structures. This eliminates the need for separate packaging and construction materials, reducing waste and transportation costs.

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

2Ease of manufacture

If conventional construction materials are shipped, then building structures can be constructed, but the materials are expensive to ship and require skilled labor

Engineering Contradiction:
Improveconstruction costVSAvoidshipping weight
Core Design Contradiction:
Ease of manufactureVSWeight of moving object

Solution Approach 1:

The shipping container is designed to serve as both a transport vessel and a construction block. By making the container itself the building material, the patent eliminates the need to ship separate construction materials, significantly reducing shipping weight and costs while simplifying construction.

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

Solution Approach 2:

The patent replaces expensive, heavy conventional construction materials with a lighter, more economical container design that can be reused. The container structure is optimized to provide sufficient construction strength while minimizing weight, making it a cost-effective alternative to traditional building materials.

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

3Productivity

If conventional structures are built, then shelter can be provided, but the construction process is slow and requires waiting for materials and skilled labor

Engineering Contradiction:
Improveconstruction speedVSAvoidwaiting time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The containers are pre-prepared and pre-positioned for immediate use as construction blocks. Since the containers are already manufactured and designed with construction functionality built-in, there is no need to wait for material delivery or skilled labor assembly, enabling rapid deployment of shelter structures.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The container design enables self-assembly as construction blocks without requiring skilled labor. The standardized structure and interlocking mechanisms allow for quick assembly by unskilled personnel, dramatically reducing construction time and eliminating delays associated with finding and coordinating skilled workers.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If containers are used as building blocks, then shelter can be constructed immediately, but the containers need interlocking support to prevent load shifting during transportation

Engineering Contradiction:
Improvecontainer dual useVSAvoidinterlocking mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container is designed with universal features that serve both shipping and construction functions. The same structural elements that provide stability during shipping also enable interlocking and load distribution during construction, eliminating the need for separate specialized features and reducing overall complexity.

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

AI summary

A plastic construction block for storage of water, food, medicine, staples, construction materials, or any other item that needs to be contained for storage and shipping. The construction block can also be used in the construction of a bunker, wall, or the like structure through conventional building construction by filling of the block with sand or dirt. The construction block is substantially rectangular in shape having an enlarged fill port on one end with a resealable cap. The interior of the block is hollow and sized to hold about 3.4 fluid gallons. Apertures extend through the block and are used for receipt of anchoring posts. Each aperture further having a raised protrusion formed integral along one surface and a receptacle placed around each aperture on the rear surface. The raised protrusion interlocking with a receptacle on a rear surface of an adjoining construction block for aligning similar shaped construction blocks. The construction block further including at least one anchoring pipe retaining socket, said pipe retaining socket having a depth of approximately one half the diameter of an anchoring pipe allowing retention for use in storage and shipping.
