Solution Overview

Problem

Existing interface systems for operators are uncomfortable, cause discomfort or pain upon prolonged use, and are unsuitable for multiple users due to design limitations.

Innovation Solution

An interface system comprising a frame positioned on the operator's torso with contact units on the thoracic region and hips, featuring elastic bodies between supports to distribute forces, allowing for adaptability and comfort, and flexible elements for connection, designed to relieve sensitive areas like the neck, shoulders, and abdominal region.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a rigid frame structure is used to provide structural support, then strength and stability are improved, but comfort and adaptability to different operators deteriorate

Engineering Contradiction:
Improvestructural supportVSAvoidadaptability to different operators
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The frame is divided into multiple segments including upper support elements, lower support elements, and intermediate elements that can move relative to each other. This segmentation allows the rigid frame to adapt to different operator bodies while maintaining structural integrity and force distribution capabilities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The frame incorporates dynamic elements such as movable intermediate elements and adjustable connections that allow the structure to adapt its configuration based on the operator's posture and body shape, enabling a single rigid frame design to serve multiple operators comfortably.

Inventive Principle:
Principle #15Dynamics

2Force

If contact units are positioned on the thoracic region and hips, then force distribution is improved, but discomfort and pain upon prolonged use worsen

Engineering Contradiction:
Improveforce distributionVSAvoiddiscomfort and pain
Core Design Contradiction:
ForceVSObject-affected harmful factors

Solution Approach 1:

Different contact units are designed with specific local qualities - softer materials and larger contact areas for the thoracic region to reduce pressure, and optimized contact points for the hips. This localized optimization of contact unit properties prevents discomfort and pain while maintaining effective force distribution.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If the interface system is designed for a specific operator build, then comfort for that operator is improved, but suitability for multiple users deteriorates

Engineering Contradiction:
ImprovecomfortVSAvoidsuitability for multiple users
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The interface system is designed with universal adaptability through adjustable connections, movable elements, and configurable contact unit positions that allow the same system to be comfortably worn by operators of different builds, postures, and body types, eliminating the need for operator-specific customization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If flexible elements are used to connect contact units to the frame, then adaptability and comfort are improved, but structural stability deteriorates

Engineering Contradiction:
ImproveadaptabilityVSAvoidstructural stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The flexible elements are designed with controlled flexibility that allows adaptation to operator movement and body shape changes while maintaining sufficient structural stability through appropriate material selection and geometric configuration, achieving a balance between adaptability and stability.

Inventive Principle:
Principle #15Dynamics
