Solution Overview

Problem

Existing transport tools face challenges in accurately positioning heavy objects at predetermined attachment positions, requiring complex operations and heavy machinery movement, which can be cumbersome and space-constrained.

Innovation Solution

A transport tool with a movable holding section and positioning section that aligns the object at a preparation position relative to the attachment position, allowing for easy attachment without moving heavy machinery, using a base, holding section, and positioning section to facilitate precise positioning and attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If heavy machinery is used to position and attach heavy objects, then the attachment operation can be performed, but the operation becomes cumbersome and requires moving heavy machinery which is difficult in space-constrained environments

Engineering Contradiction:

Improveease of attachment operationVSAvoidcomplexity of heavy machinery movement

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The transport tool is divided into distinct functional sections: a base for stability, a movable holding section for grasping the object, and a positioning section with engagement protrusions for precise alignment. This segmentation allows each part to perform its specific function independently, enabling easy attachment operations without requiring complex heavy machinery.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transport tool acts as an intermediary device between the operator and the heavy object. The positioning section with engagement protrusions interfaces with corresponding recesses on the object, providing precise positioning without requiring direct manipulation by heavy machinery. This intermediary mechanism simplifies the attachment operation while maintaining accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If heavy machinery is moved to position the object at the attachment position, then precise positioning can be achieved, but the operation becomes time-consuming and space-consuming

Engineering Contradiction:

Improveprecision of object positioningVSAvoidtime for positioning operation

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The positioning section is designed with engagement protrusions that pre-align with corresponding recesses on the object at the predetermined attachment position. This preliminary positioning design allows the object to be accurately positioned simply by moving the holding section, eliminating the need for time-consuming heavy machinery repositioning and achieving precise alignment quickly.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The holding section is designed to be movable relative to the base, allowing dynamic adjustment of the object's position. This mobility enables the holding section to carry the object directly to the attachment position and engage it quickly, achieving precise positioning without the time loss associated with moving heavy machinery.

Inventive Principle:

Principle #15Dynamics

3Manufacturing precision

If the holding section is fixed relative to the base, then the structure is simple, but the object cannot be positioned at the preparation position with predetermined positional relationship

Engineering Contradiction:

Improveprecision of positional relationshipVSAvoidcomplexity of movable holding section

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The transport tool is segmented into a fixed base and a movable holding section, with the positioning section providing engagement features. This segmentation allows the holding section to move independently to achieve precise positional relationships while keeping the base structure simple and stable.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The positioning section is provided with specific engagement protrusions at particular locations on the base, creating localized positioning features. This allows precise positioning functionality to be added without complicating the entire structure, as only specific areas of the base require positioning features while the rest remains simple.

Inventive Principle:

Principle #3Local quality

AI summary

A transport tool capable of carrying out attaching an object to an attachment position while positioning the object in a predetermined positional relationship with the attachment position. The transport tool includes a base, a holding section movably supported by the base in a predetermined direction and configured to hold an object, and a positioning section that is provided to the base and configured to arrange the object held by the holding section in a preparation position having a predetermined positional relationship with the attachment position, the positioning section allowing the execution of an attachment operation of attaching the object, which has been arranged in the preparation position, to the attachment position by movement of the holding section relative to the base.
