Solution Overview

Problem

Existing attachment devices for securing loads in transport vehicles often fail to detach easily, leading to difficulties in removing the secured load due to deformation during transport.

Innovation Solution

The attachment device incorporates a spring-loaded latching element and a handle on the hinge pin, allowing for quick insertion and removal from aligned bores, enabling easy detachment of the securing means from the hook, which remains engaged in the transport wall opening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the attachment device uses a fixed connecting element rigidly attached to the hook, then the structural strength and stability are improved, but the ease of detachment deteriorates when the securing means is deformed during transport

Engineering Contradiction:
Improvestructural strengthVSAvoidease of detachment
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The connecting element is divided into a hook portion and a connecting portion that can be detached from each other. The hinge pin allows these segments to be separated, enabling the connecting element to be detached from the hook even when the securing means is deformed, while maintaining structural strength when connected.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting element transitions from a rigid fixed connection to a dynamic detachable connection. The hinge pin with spring-loaded latching element provides a mechanism that allows the connecting element to be easily attached and detached, adapting to deformed states of the securing means while maintaining strength during use.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the attachment device uses a detachable connecting element for easy removal, then the ease of operation is improved, but the structural strength and stability deteriorate

Engineering Contradiction:
Improveease of detachmentVSAvoidstructural strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The hinge pin connection provides a dynamic balance between ease of detachment and structural strength. When connected, the hinge pin creates a rigid joint that maintains structural integrity. When detachment is needed, the spring-loaded latching element allows easy release by overcoming the spring force, providing both strength and operational ease.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The hinge pin acts as an intermediary between the hook portion and connecting portion. It provides a standardized interface that ensures strong connection when engaged, while allowing easy detachment through the spring-loaded mechanism. This intermediary element mediates between the conflicting requirements of strength and ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the attachment device uses a complex locking mechanism to ensure secure retention, then the reliability is improved, but the device complexity increases

Engineering Contradiction:
Improvesecure retentionVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The spring-loaded latching element on the hinge pin provides automatic engagement and locking. When the hinge pin is inserted, the spring-loaded element automatically latches into position, providing secure retention without requiring additional complex locking mechanisms. The system serves itself by using the insertion motion to trigger the locking action.

Inventive Principle:
Principle #25Self-service
