Solution Overview

Problem

Existing coupling systems for loudspeaker housings require setting the angle between units while they are hoisted, leading to safety risks due to gravitational forces and complexity in alignment, which can result in accidents and inefficiencies.

Innovation Solution

A coupling system that sets the predetermined angle when the loudspeaker housings are in a non-hoisted, stretched position, allowing them to move into the desired angle under gravity, reducing human intervention and safety risks, and enabling efficient hoisting and lowering with minimal curvature.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the angle between loudspeaker housings is set while they are in a hoisted position, then the loudspeaker housings can be coupled at the correct angle for optimal sound quality, but gravitational forces are exerted on the loudspeaker housings creating safety risks and making the setting operation difficult

Engineering Contradiction:
Improveangle setting precisionVSAvoidgravitational forces
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The coupling system performs the angle setting action preliminarily when the loudspeaker housings are in a non-hoisted position on the ground, before the hoisting operation begins. The coupling means are configured to set the predetermined angle between housings while they are accessible and stationary, eliminating the need to perform angle setting during the hazardous hoisted state. This preliminary configuration ensures both safety and precision.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If the angle between loudspeaker housings is set while they are in a hoisted position, then the correct angle can be achieved, but the operation becomes complex and time-consuming due to alignment difficulties

Engineering Contradiction:

Core Design Contradiction:

3Ease of operation

If the loudspeaker housings are moved from non-hoisted to hoisted position after angle setting, then human intervention is minimized and safety is improved, but the movement requires coordination to maintain the set angle

Engineering Contradiction:
ImprovesafetyVSAvoidmovement coordination
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The coupling system segments the operational sequence into distinct phases: first, angle setting is performed on the ground when housings are stationary and accessible; second, the housings are hoisted as a pre-configured unit. The coupling means maintain the predetermined angle configuration throughout the transition, separating the complex angle-setting operation from the hoisting operation to improve safety.

Inventive Principle:
Principle #1Segmentation

4Manufacturing precision

If the loudspeaker housings extend at the predetermined angle during hoisting, then the correct configuration is maintained, but the row of housings exhibits curvature and occupies more space

Engineering Contradiction:
Improveangle configurationVSAvoidspace occupation
Core Design Contradiction:
Manufacturing precisionVSArea of stationary object

Solution Approach 1:

The coupling system allows the loudspeaker housings to dynamically transition from a stretched, linear configuration during ground-based angle setting to the predetermined angled configuration during hoisting. The coupling means are designed to accommodate this dynamic transformation, enabling the housings to extend linearly when not hoisted (minimizing space occupation) while maintaining the correct angle configuration when hoisted.

Inventive Principle:
Principle #15Dynamics
