Solution Overview

Problem

Existing ballistic shields face challenges in efficiently transferring power and signals between accessories while maintaining structural integrity and reducing electromagnetic signature, with current methods compromising strength or causing cable tangling and signal interference.

Innovation Solution

A shield system with a shield body featuring an edging that incorporates connectors for direct power and signal transfer between accessories on opposite sides, eliminating the need for external cables and reducing electromagnetic interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If electrical power is transmitted through a hole in the shield, then power transfer between accessories is enabled, but the strength of the shield is compromised

Engineering Contradiction:

Improvepower transferVSAvoidshield strength

Core Design Contradiction:

Use of energy by moving objectVSStrength

Solution Approach 1:

The patent introduces an intermediary mechanism (conductive elements integrated into the shield structure) to transfer power without creating direct holes through the shield body. This mediator allows electrical connection while preserving the structural integrity of the ballistic shield.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The conductive elements are nested within the shield structure itself, utilizing the existing shield body as part of the electrical pathway. This integration allows power transmission through the shield without requiring separate penetrating cables that would compromise strength.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Use of energy by moving object

If accessories are connected by an electrical power cable led around the outer edge of the shield, then power transfer is enabled, but the cable may tangle with and/or snag behind other objects

Engineering Contradiction:

Improvepower transferVSAvoidcable management

Core Design Contradiction:

Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent extracts the external cable from the system by integrating the electrical connection directly into the shield structure. This eliminates the problematic external cable that would tangle or snag, while maintaining the power transfer function between accessories.

Inventive Principle:

Principle #2Taking out (Extraction)

3Use of energy by moving object

If inductive power transmission is used, then power transfer without direct connection is achieved, but power loss rises dramatically with imperfect alignment and distance

Engineering Contradiction:

Improvepower transferVSAvoidpower loss

Core Design Contradiction:

Use of energy by moving objectVSLoss of energy

Solution Approach 1:

The patent replaces the inductive (electromagnetic field-based) power transmission system with a direct conductive connection integrated into the shield. This mechanical/electrical connection provides reliable power transfer without the alignment sensitivity and energy losses inherent in inductive systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A shield system comprises a protective shield body, a first accessory and a second accessory. The shield body comprises a shield panel provided with an edging, the shield panel having a first and second face defining a threat side in a threat direction and a protected side in a protected direction opposite the threat side and threat direction, respectively and having opposite panel edges, the edging covering at least part of the panel edges. The edging of the shield body comprises connectors operably connected with each other. The first and second accessories are operably connectable or connected with each other via the connectors for power and/or a signal transfer from the first accessory to the second accessory and/or back via the connectors.
