Solution Overview

Problem

Existing tool belts lack optimal surface contact with the user's body, leading to slippage and discomfort due to their straight design, which results in hot spots and poor weight distribution.

Innovation Solution

A tool belt with three segments: a rear transfer pad that allows adjustment in length, curvature, and stiffness, and two wings that can be connected to the transfer pad and each other, enabling customizable fit and maximum surface contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a tool belt is designed with a straight design, then it is simple in structure and easy to manufacture, but it does not allow optimal surface contact with the user's body, leading to slippage and discomfort

Engineering Contradiction:

Improvesimplicity of structureVSAvoidsurface contact stability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The tool belt is divided into three separate segments: a rear transfer pad and two wings. These segments can be independently adjusted and connected at various angles, allowing the belt to conform to the user's body contours while maintaining structural simplicity and ease of manufacture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection between the rear transfer pad and the wings is made adjustable and flexible, allowing the user to modify the curvature and configuration of the belt. This dynamic adjustment capability enables the rigid segments to achieve a flexible fit that maintains optimal surface contact without complicating the manufacturing process.

Inventive Principle:

Principle #15Dynamics

2Reliability

If a tool belt is curved to maintain better surface contact, then it improves comfort and weight distribution, but it cannot accommodate every individual's unique body form

Engineering Contradiction:

Improvesurface contact qualityVSAvoidcompatibility with different body forms

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

By segmenting the belt into adjustable components, each user can configure the curvature to match their specific body form. The segmentation allows customization of the arc and angle adjustments to accommodate diverse anatomical variations while maintaining consistent surface contact quality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The adjustable connections enable the belt to dynamically adapt its curvature to different body forms. Users can modify the configuration to suit their unique anatomy, making the curved design universally adaptable rather than fixed for a single body type.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If the connection between wings and transfer pad is fixed, then the structure is stable and simple, but it cannot be adjusted for different users or changing conditions

Engineering Contradiction:

Improvestructural stabilityVSAvoidadjustability for different users

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The connection mechanism between the wings and rear transfer pad is designed to be dynamically adjustable. Users can modify the connection points and angles according to their body form and clothing thickness, while the connected structure maintains stability during use. This dynamic adjustability resolves the contradiction between fixed stability and flexible adaptability.

Inventive Principle:

Principle #15Dynamics

4Device complexity

If the tool belt does not have maximum surface contact, then it reduces manufacturing complexity, but it causes hot spots and discomfort on the hips

Engineering Contradiction:

Improvebelt configuration simplicityVSAvoidhot spots and discomfort

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The segmented design with adjustable connections allows the belt to be configured to achieve maximum surface contact without requiring a complex pre-formed curved structure. The simple segments can be arranged to conform to the body, distributing weight evenly and eliminating hot spots while maintaining manufacturing simplicity.

Inventive Principle:

Principle #1Segmentation

AI summary

Embodiments of the present disclosure provide a multi-segmented belt apparatus. In different embodiments, one segment is a rear transfer pad and two other segments are wings, each having one end for connecting to the other wing and another end for connecting to the transfer pad. The variability in connection between each wing and the transfer pad includes the ability to adjust the curvature and length of the belt to ensure that the belt has maximum surface contact and avoids hot spots on the hips.
