Solution Overview

Problem

Existing connection devices for setting up line arrays of loudspeaker boxes suspended beneath one another are inefficient in terms of assembly and disassembly time, safety, and adaptability to varying deployment conditions, and lack flexibility in setting up methods.

Innovation Solution

A connection device with preselectable free path length and position of assembly rails allows for multiple setting-up methods, enabling quick and safe assembly/disassembly by defining target angles through adjustable latching parts and retaining elements, compatible with both tension and compression methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed connection device is used for loudspeaker boxes, then the connection is reliable and safe, but the assembly and disassembly time is long and the adaptability to varying deployment conditions is poor

Engineering Contradiction:

Improveconnection reliabilityVSAvoidassembly and disassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The connection device incorporates adjustable connection elements that allow the distance between loudspeaker boxes to be varied dynamically. The connection device transitions from a fixed structure to one with movable components, enabling quick adjustment of the number of loudspeaker boxes in the arrangement without complete disassembly, thus reducing setup time while maintaining connection reliability through secure locking mechanisms.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The connection device enables changing the geometric parameters of the loudspeaker box arrangement by allowing adjustment of the distance between individual boxes. This parameter change capability permits the same connection device to accommodate different deployment conditions and audience sizes without requiring multiple specialized connection systems, thereby reducing assembly time for different configurations.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If a fixed connection device is used for loudspeaker boxes, then the structure is simple, but the adaptability to varying deployment conditions is poor

Engineering Contradiction:

Improveconnection device structureVSAvoidadaptability to deployment conditions

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The connection device is designed with universal applicability, where a single connection device can accommodate multiple loudspeaker boxes in series and adapt to different deployment conditions. The adjustable connection elements allow the same device to function with varying numbers of loudspeaker boxes and different spatial configurations, providing multi-functionality without requiring complex specialized devices for each scenario.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The connection device incorporates dynamic adjustment capabilities that allow it to adapt to different deployment conditions. The movable connection elements enable the device to accommodate varying distances and angles between loudspeaker boxes, making a single device type suitable for multiple application scenarios without increasing overall structural complexity.

Inventive Principle:

Principle #15Dynamics

3Reliability

If heavy lifting works are performed during setting up and taking down, then the connection is secure, but the risk of accidents increases and assembly time increases

Engineering Contradiction:

Improveconnection securityVSAvoidrisk of accidents

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The connection device incorporates self-aligning and self-locking features that reduce the need for heavy manual lifting and positioning. The loudspeaker boxes can be connected with minimal lifting effort as the connection device automatically guides and secures the connection, thereby reducing accident risk while maintaining secure connections through automated locking mechanisms.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The connection device acts as an intermediary that facilitates easy connection between loudspeaker boxes without requiring direct heavy lifting. The intermediate connection elements distribute the weight and force, allowing workers to connect boxes with minimal lifting effort while the connection device itself bears the load, reducing accident risk while ensuring secure connections.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A connection device for setting up an arrangement of a plurality of loudspeaker boxes that are suspended beneath one another comprises a first assembly rail which is provided for assembly on a first loudspeaker box and to which a latching part is attached, and a second assembly rail which is provided for assembly on a second loudspeaker box and to which a retaining element that interacts with the latching part is attached. Herein, a free path length of a longitudinal displaceability of the latching part in relation to the first assembly rail is preselectable. Furthermore, the position of the retaining element in relation to the second assembly rail is preselectable.
