Solution Overview

Problem

Existing solutions for protecting items from flood hazards lack versatility and effectiveness in preserving items of various sizes and shapes, especially for large objects like vehicles, which require both watertightness and floatability, while also ensuring space-saving designs and stability during floods.

Innovation Solution

A foldable, waterproof bag with a cuboid lower part and a separate upper part that can be connected with non-hermetical fixing details, equipped with stabilizers for floatability and anchoring points, allowing for adjustable dimensions and enhanced protection against water displacement, lateral movement, and potential collisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the bag is made completely hermetically watertight, then protection against water from all directions is improved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:
ImprovewatertightnessVSAvoidcomplexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bag is divided into a lower part and an upper part that are connected but not fully integrated. The lower part provides hermetic sealing while the upper part provides cover protection, allowing each part to be optimized independently for its specific function.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different parts of the bag have different sealing requirements. The lower part is made completely hermetically sealed for full waterproof protection, while the upper part uses non-hermetic connections sufficient for preventing precipitation from above, reducing overall complexity.

Inventive Principle:
Principle #3Local quality

2Volume of moving object

If the bag is made foldable from planar form, then space saving is improved, but manufacturing precision and assembly difficulty increase

Engineering Contradiction:
Improvestorage volumeVSAvoidprecision
Core Design Contradiction:
Volume of moving objectVSManufacturing precision

Solution Approach 1:

The bag is pre-folded into a compact planar form before use, with folding lines and connection points pre-positioned to ensure proper assembly. This preliminary preparation simplifies the folding process and ensures consistent results.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The bag can be folded into a compact nested form that fits within itself, maximizing space efficiency while maintaining the ability to expand to full size when needed.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If separate lower and upper parts are used with non-hermetical fixing, then ease of assembly and device simplicity are improved, but protection against water infiltration increases

Engineering Contradiction:
Improveease of assemblyVSAvoidwatertightness
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The bag is divided into a lower part and an upper part that are connected but not fully integrated. The lower part provides hermetic sealing while the upper part provides cover protection, allowing each part to be optimized independently for its specific function.

Inventive Principle:
Principle #1Segmentation

4Stability of the object's composition

If stabilizers are added for floatability and stability, then stability and floatability are improved, but device complexity and weight increase

Engineering Contradiction:
ImprovestabilityVSAvoidcomplexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The stabilizers are integrated into the bag structure itself rather than being separate components. The lower part of the bag is designed to provide both structural support and stabilization functions, combining multiple functions into a single element.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bag structure itself provides stabilization and floatability through its design, eliminating the need for separate stabilization components. The lower part's construction inherently provides the necessary stability and buoyancy.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution provides comprehensive protection and preservation of items by ensuring watertightness from below and sides, floatability, and stability against water-induced forces, preventing sinking and lateral damage, while allowing for space-efficient storage and easy deployment.

Implementation Method 1

the lower part ensures complete watertightness of the item from below and from the sides, and upon flood situation also floatability of the item

Methodology Applied
Scientific EffectWater displacement: Archimedes' Principle (Buoyancy)

Implementation Method 2

Stabilizers may be filled with gas, liquids or gel. At the same time the stabilizers ensure stability of the floating object and prevent its overturning and sinking

AI summary

This invention concerns watertight ready-made or foldable storage bag suitable for preservation of items with various size and shape and protection of items against flood hazards. Bag of the invention includes in preferred embodiment the lower part (1) in the main shape of cuboid made of watertight material, and the upper part (2), which upper edge is watertightly sealed with methods known from the prior art. The bag of preferred embodiment is foldable from planar form with suitable shape immediately before the need for preservation of the item, which is especially useful for space saving in case of large items. For smaller items the bag may be pre-folded, so that upon necessity the preserved item can be placed into it, closing the bag watertightly with its upper part. Dimensions of the bag may vary and depend on the dimensions of the item placed within. In this alternative option lower and upper parts (1,2) of watertight storage bag are separate parts, so that the lower part (1) ensures complete watertightness of the item from below and from the sides, and upon flood situation also floatability of the item, while the tent of upper part ensures watertightness of the item against precipitation from above.
