Solution Overview

Problem

Existing transport devices for vibratory plate compactors, which can swivel between storage and transport positions, are inconvenient to adjust.

Innovation Solution

A vibratory plate compactor design featuring a transport device pivotally mounted on a superstructure with a locking mechanism and swivel drive gear, allowing for a single actuating movement to switch between positions, and a locking element that secures the device in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If transport wheels are pivotably mounted on the vibratory plate between storage and transport positions, then the transport device can be adjusted between positions, but the adjustment process is inconvenient

Engineering Contradiction:
Improveadjustability between positionsVSAvoidconvenience of adjustment
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The transport device utilizes the weight of the vibratory plate compactor itself to automatically pivot the bearing arms into the transport position. When the locking element is actuated to release the locked position, gravity causes the bearing arms to swing downward and forward, jack up the compactor, and position the wheels on the ground automatically, eliminating the need for manual positioning operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The design pre-positions the bearing arms and locking mechanism such that actuation of the locking element automatically initiates the entire adjustment sequence. The bearing arms are preliminarily configured to pivot in a specific trajectory that first releases the lock, then uses gravitational force to swing the arms into the transport position, and finally locks automatically at the end position.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If a locking mechanism is added to secure the transport device in position, then stability is improved, but device complexity increases

Engineering Contradiction:
Improvestability in positionVSAvoidcomplexity of transport device
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking element serves multiple functions simultaneously: it locks the bearing arms in the stowed position, initiates the pivoting movement when actuated, and automatically re-locks at the transport position. This multi-functionality consolidates what could be separate locking and actuating mechanisms into a single integrated component, reducing overall device complexity while maintaining reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The locking element is designed as a multi-functional component that operates in both locked and unlocked states, serving as both a security device and an actuating mechanism. The same element that secures the device in one position also triggers the transition to another position, eliminating the need for separate locking and actuating systems.

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