Body Protector Pad Overlap for Penetration Prevention

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional body protectors lack effective solutions for preventing penetration through flexible breaks between pad members, which can compromise protection and comfort.

Innovation Solution

The body protector design features overlapping foam pad members with flexible breaks, where inner pad members are offset relative to outer pad members to eliminate penetration, and includes a torsion-flex spinal pad and adjustable securing members for enhanced fit and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If flexible breaks are formed between adjacent pad members to allow body movement, then comfort and flexibility are improved, but penetration through the flexible breaks can occur compromising protection

Engineering Contradiction:

ImproveflexibilityVSAvoidprotection

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements nested layers of pad members where inner pad members are positioned within or behind outer pad members. The inner pad members specifically overlap the flexible breaks between outer pad members, creating a nested structure where each layer provides protection for the vulnerabilities of the outer layer while maintaining flexibility.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent transitions from a single-layer pad structure to a multi-layer structure with inner and outer pad members arranged in different spatial dimensions. The inner pad members are offset in the depth dimension relative to outer pad members, allowing them to cover flexible breaks that exist in the outer layer, thereby eliminating penetration paths while preserving flexibility.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If multiple overlapping pad members are used to prevent penetration, then protection is improved, but device complexity increases

Engineering Contradiction:

ImproveprotectionVSAvoidstructure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the protective padding system into segmented pad members rather than using a single continuous layer. Each pad member is a discrete unit that can be independently positioned and secured, allowing the system to achieve enhanced protection through multiple layers while maintaining manageable complexity through modular design.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent designs pad members that serve multiple functions: outer pad members provide primary protection and flexibility, while inner pad members provide secondary protection by covering flexible breaks. The same basic pad member structure is used in both outer and inner layers, reducing design complexity while achieving multi-functional protection.

Inventive Principle:

Principle #6Universality (Multi-functionality)
