Solution Overview

Problem

Conventional object carriers fail to adjust the center of gravity according to the user's body shape or the weight/length of the object carried, leading to discomfort and inconvenience.

Innovation Solution

An object carrier design featuring a sheet body with adjustable straps and through holes, allowing the user to select different attachment points for the connecting member, such as a waistband or strap, to adjust the center of gravity, and incorporating a strap body that can bend to form an annular hole for additional attachment options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional object carrier uses a fixed structure, then the structure is simple and easy to manufacture, but it cannot adjust the center of gravity to fit different body shapes or object weights

Engineering Contradiction:
Improveadjustability of center of gravityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The object carrier is divided into multiple segments including a sheet body, multiple first straps, a strap body, and multiple second straps. Each component can be independently positioned or adjusted, enabling the center of gravity to be customized for different body shapes and object weights while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The object carrier incorporates adjustable straps with through holes that allow dynamic repositioning. The connecting member can be moved between different through holes on the first straps and second straps, enabling the center of gravity to be adjusted according to different carrying needs without complicating the basic structure.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the object carrier provides multiple attachment points for adjusting center of gravity, then the adaptability improves, but the number of components and structural complexity increases

Engineering Contradiction:
Improvenumber of attachment pointsVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The first straps and second straps serve multiple functions: they connect the sheet body, provide attachment points for the connecting member, and enable center of gravity adjustment. The through holes in these straps universally serve as attachment points, reducing the need for separate adjustment mechanisms and minimizing component count while maintaining high adaptability.

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

AI summary

An object carrier includes a sheet body, at least two first straps, a strap body, and at least two second straps. The sheet body has a receiving space therein and an upper opening and a lower opening. The sheet body has a first surface and a second surface opposite to the first surface. The second surface has a connecting portion for connecting to an object. Each of the first straps and the first surface are connected and jointly form at least one first through hole. The strap body has a free end and a connecting end connected to the first surface and located at the upper opening. The strap body has a third surface and a fourth surface opposite to the third surface. The first surface extends to form the third surface. Each of the second straps and the fourth surface are connected and jointly form a second through hole.
