Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing loudspeakers face challenges in positioning flexibility without damaging cables or connectors, reducing technical volume, or generating vibrations and noise, especially when installed against vertical surfaces.

Innovation Solution

A connector configuration allowing for translation along a bisector plane, enabling connection in two symmetrical positions, with faces perpendicular to each other, and a complementary connector design that maintains cable alignment regardless of the speaker's orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a guide channel is added to position the cable, then the speaker can be installed in multiple positions, but the technical volume inside the enclosure is reduced

Engineering Contradiction:

Improveinstallation positionsVSAvoidtechnical volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The connector is positioned at a corner of the external housing and oriented along the bisector plane of two adjacent faces, allowing the cable to exit in different directions depending on the installation orientation. This angular positioning enables the same connector configuration to serve both horizontal and vertical installation positions without requiring additional guide channels that would consume internal volume.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If adapters are added to change cable orientation, then multiple installation positions are possible, but vibrations and unwanted noise are generated

Engineering Contradiction:

Improveinstallation positionsVSAvoidvibrations and noise

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The invention removes the need for separate adapter components by integrating the angular connector configuration directly into the equipment housing. The connector is built-in and permanently oriented along the bisector plane, eliminating the need for additional adapter parts that would cause vibrations and noise during operation.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If the connector is positioned at the rear panel, then the connection is secure, but the speaker cannot be installed against a vertical surface

Engineering Contradiction:

Improveconnector connectionVSAvoidinstallation positions

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The connector is positioned asymmetrically at a corner of the external housing rather than at the center of the rear panel. This corner positioning along the bisector plane of two adjacent faces creates an asymmetric configuration that naturally accommodates both horizontal and vertical installation orientations, maintaining secure connection in either position.

Inventive Principle:

Principle #4Asymmetry

AI summary

Equipment (1) comprising an external housing (4) comprising two first adjacent faces (9, 10), and a connector (15) positioned at least partially inside the external housing, the connector being arranged to be connected to a complementary connector (22) by translation of the complementary connector relative to the connector (15) along a connection axis (X1) included in a first bisector plane (Ps1) of first planes (P1, P2) in which the two first faces extend.
