Solution Overview

Problem

Existing protective devices for body impact and shock protection are bulky and inefficient in absorbing and distributing compressive forces, and they cause friction when worn, especially during activities like film or television recordings.

Innovation Solution

A device comprising an overcoat and a flat protective insert made of addition-curing silicone material with a Shore A hardness range of 2 to 75, anatomically shaped to fit specific body parts, which efficiently absorbs and distributes impact forces while minimizing bulkiness and friction, using a layer structure with varying hardness for optimized protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional protective devices are used for body impact protection, then protection function is provided, but the devices become bulky and cause friction when worn

Engineering Contradiction:
Improveprotection functionVSAvoidbulk
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent employs a thin film structure made of silicone material with varying local densities to achieve impact protection. The protective device consists of a thin base layer (1-10 micrometers) with localized denser regions that absorb impact forces, eliminating the need for bulky traditional protective gear while maintaining protection functionality.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The protective device features non-uniform material distribution with different local densities. The silicone material has base density in certain regions and higher density in impact-prone areas, allowing targeted protection where needed while keeping other areas thin and flexible, thus reducing overall bulk.

Inventive Principle:
Principle #3Local quality

2Reliability

If conventional protective devices are used for body impact protection, then protection function is provided, but friction occurs when worn during movement

Engineering Contradiction:
Improveprotection functionVSAvoidfriction
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The thin film structure conformally follows body contours and moves naturally with the body, minimizing relative motion and friction between the protective device and skin during movement, while still providing adequate impact protection through localized density variations.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The protective device is designed to be dynamic and adaptable to body movement. The flexible thin film structure naturally deforms and moves with the body, maintaining close contact without creating friction, unlike rigid conventional protective gear.

Inventive Principle:
Principle #15Dynamics

3Volume of moving object

If protective devices are made smaller to reduce bulk, then wearability is improved, but impact absorption capability may be reduced

Engineering Contradiction:
ImprovebulkVSAvoidimpact absorption
Core Design Contradiction:
Volume of moving objectVSStrength

Solution Approach 1:

The device compensates for reduced overall volume by concentrating material density in specific impact-absorbing zones. The non-uniform density distribution ensures that critical impact areas have sufficient material thickness and density for protection, while non-critical areas remain thin to minimize bulk.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The protective device uses a composite structure with silicone material exhibiting varying local densities. This composite approach allows the thin film to achieve high impact absorption capacity in localized regions without increasing overall device volume, combining the benefits of thinness and protection.

Inventive Principle:
Principle #40Composite materials
