Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing loudspeaker rigging systems are costly and complex due to the need for multiple pins and holes to adjust splay angles and secure connectors, leading to increased complexity and space requirements.

Innovation Solution

A simplified apparatus using a link member with adjusting through holes and anchor plates secured to speakers, allowing adjustment of splay angles using a single pin, reducing the number of holes and pins required, and enabling incremental angle adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If two pins are used to adjust the splay angle between adjacent line array speakers, then the splay angle can be adjusted and rigidly maintained, but the cost and complexity of the system increases

Engineering Contradiction:

Improvesplay angle maintenanceVSAvoidnumber of pins

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes one pin from the traditional two-pin system, extracting only the essential fastening function while eliminating redundant complexity. The single pin combined with the adjustable link mechanism achieves both angle adjustment and rigid maintenance without requiring two separate pins.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The single pin serves multiple functions: it acts as both the fastening element and the adjustment reference point. The adjustable link mechanism integrates the angle adjustment capability directly into the connection structure, making the pin a multi-functional component that maintains reliability while reducing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple holes are used to secure connectors and adjust positions, then various positions and angles can be achieved, but the number of holes and pins required increases

Engineering Contradiction:

Improveposition adjustment capabilityVSAvoidnumber of holes and pins

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent introduces a dynamic adjustment mechanism where the link can be rotated to different positions, allowing a single pin-hole combination to provide multiple positioning options. This dynamic capability replaces the need for multiple static holes and pins while maintaining full position adjustment versatility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The adjustable link is pre-configured with multiple position markings and can be quickly rotated to desired positions without requiring multiple pins or holes. This preliminary preparation of adjustment positions allows for versatile positioning while using minimal fastening components.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If side frames and splay adjustment links with multiple pin holes are used, then splay angle adjustments can be made, but the cost and complexity of the rigging system increases greatly

Engineering Contradiction:

Improvesplay angle adjustment rangeVSAvoidrigging system structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the splay adjustment function directly into the link member itself, eliminating the need for separate side frames and adjustment links. The combined structure uses a single adjustable link with integrated pin holes, reducing the overall number of components while maintaining the full splay angle adjustment range.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The adjustment mechanism is segmented into discrete, modular components where the link member can be independently adjusted and locked at specific positions. This segmentation allows for simple, incremental adjustments without requiring complex integrated structures, reducing overall system complexity while maintaining versatility.

Inventive Principle:

Principle #1Segmentation

4Adaptability or versatility

If holes are spaced out perpendicular to the primary direction of adjustment, then multiple adjustment positions can be achieved, but the space required increases greatly

Engineering Contradiction:

Improveadjustment positionsVSAvoidspace required

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent transitions from a two-dimensional arrangement of holes spaced perpendicular to the adjustment direction to a one-dimensional linear arrangement of pin holes along the adjustment axis. This dimensional change allows multiple adjustment positions to be achieved in a compact linear space rather than requiring dispersed two-dimensional spacing.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

An apparatus for positioning two speakers relative to each other includes a link member with a first securing through hole and a first plurality of adjusting through holes. A first anchor plate which can be secured to a first speaker has a second securing through hole. A first pin is able to be passed through the first and second securing through holes to secure the link member and the first anchor plate together at a back, central location of the speaker. A second anchor plate which can be secured to a second speaker has a second plurality of adjusting through holes. A second pin is able to be passed through one of the first plurality of adjusting through holes and one of the second plurality of adjusting through holes to secure the link member and the second anchor plate together.
