Solution Overview

Problem

Existing fall protection harness belts lack versatility and comfort, particularly in elevated environments, as they often fail to provide adequate adjustability and cooling for users.

Innovation Solution

The proposed harness belt system incorporates multiple layers, including elastomer layers, ballistic material layers, memory foam, and thermoplastic layers, with adjustable configurations and ventilation features to enhance comfort and adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If traditional single-layer harness belts are used, then the structure is simple and easy to manufacture, but the comfort and ventilation are insufficient

Engineering Contradiction:

Improveventilation and coolingVSAvoidmulti-layer structure

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The harness belt is divided into multiple functional layers including a first mesh layer for ventilation, a frames layer for structural support, padding layers for comfort, ballistic material layer for protection, and thermoplastic layer for adjustability. Each layer performs a specific function, resolving the contradiction by segmenting the single structure into specialized components that collectively provide both comfort and protection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent combines different materials with distinct properties: mesh fabric for breathability, memory foam for comfort, ballistic nylon for durability and protection, thermoplastic for adjustability, and elastomer for flexibility. This composite material approach allows each material to contribute its optimal properties, achieving both ventilation and structural integrity simultaneously.

Inventive Principle:

Principle #40Composite materials

2Adaptability or versatility

If fixed configuration harness belts are used, then the manufacturing is simple, but the adaptability to different users and accessories is limited

Engineering Contradiction:

Improveadjustability and accessory configurationsVSAvoidadjustable mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The thermoplastic layer incorporates multiple belt configuration openings that allow the harness to be dynamically adjusted to different body sizes and accessory requirements. The adjustable belt system can be repositioned through various slots and openings, transforming a static structure into a dynamic, adaptable configuration that responds to different user needs while maintaining a relatively simple overall design.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The multiple belt configuration openings and adjustable belt system serve multiple functions: they accommodate different waist sizes, allow positioning of accessories at various heights, and provide flexibility for different working positions. This multi-functional design enables a single harness model to serve diverse users and applications without requiring multiple specialized designs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Strength

If heavy-duty protective materials are used, then the protection level is high, but the weight increases reducing user comfort

Engineering Contradiction:

Improveprotection levelVSAvoidharness weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The ballistic material layer is strategically positioned and configured to provide protection only where needed, rather than uniformly throughout the entire harness. The padding layers are concentrated in areas requiring cushioning, while mesh areas provide ventilation where less protection is needed. This localized approach to protection maintains high safety levels while minimizing unnecessary weight.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses thin, flexible protective layers including ballistic material and thermoplastic films that provide adequate protection without the bulk and weight of traditional heavy-duty harnesses. These thin protective films maintain strength while reducing mass, and the flexible nature allows for better conformability to the body, improving comfort without sacrificing protection.

Inventive Principle:

Principle #30Flexible shells and thin films
