Operator Interface System with Elastic Contact Units
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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
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.
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
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.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides comfort and effective force distribution, reducing strain on sensitive body regions and allowing for use by various operators with different postures and builds, while being durable and suitable for outdoor use.
Implementation Method 1
at least one elastic body 43, which is interposed between the first and the second support, and which is deformable so as to allow position and/or orientation variations between the first support 41 and the second support 42
