Solution Overview

Problem

Existing ballistic protection devices are not adaptable enough to quickly transition between dynamic and static combat situations, posing a risk to personnel as they require replacement of materials, which is not feasible in high-pressure combat environments.

Innovation Solution

A handheld ballistic shield with a handle made of high-impact resistant material, featuring a rectangular shape with connecting means for quick assembly and disassembly, allowing formation of a larger shelter system with rotational freedom between shields, ensuring continuous impact protection without gaps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If ballistic protection devices are designed for static combat situations with larger protective structures, then protection coverage is improved, but mobility and portability deteriorate

Engineering Contradiction:

Improveprotection coverage areaVSAvoidshield weight

Core Design Contradiction:

Area of stationary objectVSWeight of moving object

Solution Approach 1:

The ballistic protection system is divided into multiple modular shield units that can be used individually for personal protection or assembled together to form larger protective structures. Each shield unit maintains portability while the segmented design enables scalable protection coverage through combination of multiple units.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple shield units can be nested or assembled together to form larger protective structures when needed for static combat situations, while allowing individual shields to be used separately for dynamic situations requiring mobility.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Weight of moving object

If ballistic protection devices are designed for dynamic combat situations with portable shields, then mobility is improved, but protection coverage area deteriorates

Engineering Contradiction:

Improveshield weightVSAvoidprotection coverage area

Core Design Contradiction:

Weight of moving objectVSArea of stationary object

Solution Approach 1:

The system uses segmented modular shield units that provide adequate personal protection when carried individually for dynamic operations, while maintaining the capability to assemble multiple units for expanded coverage when the situation requires.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The protection system is designed to be dynamic and adaptable, allowing personnel to transition from using individual portable shields in mobile operations to assembling multiple shields into larger protective structures when transitioning to static combat situations.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If ballistic protection devices are designed with fixed configuration, then structural stability is improved, but adaptability to different combat situations deteriorates

Engineering Contradiction:

Improvestructural stabilityVSAvoidadaptability to combat situations

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The fixed structural stability of individual shield units is maintained while their modular segmented design enables reconfiguration into different protective arrangements adapted to various combat situations, whether dynamic or static.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each shield unit is designed with universal connecting features that allow it to function both as a standalone portable shield for dynamic operations and as a component of larger assembled protective structures for static situations, providing multi-functionality across different combat scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If ballistic protection devices allow quick conversion between configurations, then adaptability is improved, but connection reliability deteriorates

Engineering Contradiction:

Improveconversion capabilityVSAvoidconnection reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The shield units are pre-equipped with integrated connecting means and hinge members during manufacturing, allowing quick assembly and conversion between configurations while ensuring that the connection components are pre-tested and reliable from the outset.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The connecting means are designed to enable self-contained assembly and disassembly of shield units without requiring additional tools or complex procedures, maintaining both quick convertibility and connection reliability through intuitive self-service design.

Inventive Principle:

Principle #25Self-service
