Solution Overview

Problem

Existing terminal assemblies for connecting loudspeakers in parallel or series configurations require manual handling of wires and substitution of terminal blocks, leading to clutter and uncertainty in proper connections, making it difficult to switch between configurations efficiently.

Innovation Solution

A terminal assembly with first and second sets of load terminals and jumper contacts that allow for electrical connections to switch between series and parallel configurations without altering the wires, using a jumper to connect load terminals and source terminals, enabling easy switching between series and parallel connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual handling of wires and substitution of terminal blocks is used to switch between series and parallel configurations, then connection flexibility is achieved, but device complexity and ease of operation deteriorate due to clutter and difficulty in making proper connections

Engineering Contradiction:
Improveconnection flexibilityVSAvoidease of switching configurations
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The terminal assembly is divided into distinct terminal blocks for series connection and parallel connection, with each block having clearly defined connection points. This segmentation allows users to simply connect wires to the appropriate terminal block without having to manually reconfigure wire connections, thereby maintaining connection flexibility while dramatically improving ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces terminal blocks as intermediary components that simplify the connection process. Instead of directly connecting wires in series or parallel configurations, users connect wires to the terminal blocks which then establish the desired electrical connections. This intermediary approach eliminates clutter and makes proper connections straightforward.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If terminal blocks are substituted to switch between series and parallel wiring, then wiring configuration changes are achieved, but loss of time increases due to the complexity of altering wire configurations

Engineering Contradiction:
Improvewiring configuration switchingVSAvoidtime to switch configurations
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The terminal blocks are pre-configured with connection points that correspond to series and parallel wiring arrangements. This preliminary preparation eliminates the need for time-consuming wire reconfiguration, as users simply need to connect or disconnect wires from the appropriate terminal block without altering the wire configurations themselves.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The terminal assembly provides dynamic reconfigurability through easily accessible terminal blocks that can be quickly connected or disconnected. This dynamic design allows for rapid switching between series and parallel configurations without the time loss associated with manual wire reconfiguration, while maintaining full adaptability of wiring arrangements.

Inventive Principle:
Principle #15Dynamics

AI summary

A terminal assembly for selectively coupling multiple electrical loads in parallel or in series includes a plurality of jumper contacts in a spaced relationship. The jumper contacts may be in electrical communication with load terminals as well as source terminals. Connections made in a first group of electrically connectable pairings of adjacent jumper contacts couples the load terminals, and thus any loads attached thereto, in parallel. Connections made in a second group of electrically connectable pairings of adjacent jumper contacts couples the load terminals in series.
