Solution Overview

Problem

Existing solutions for connecting electrical components to a power supply, such as busbars and contact boards, are limited in their ability to form complex three-dimensional line paths, as they can only be deformed or angled to a certain extent, restricting their adaptability in complex arrangements.

Innovation Solution

A device comprising at least one three-dimensionally shaped wire with contact areas at its ends and other points, allowing for complex three-dimensional line paths, with a round cross-section for optimal deformability, and featuring flat embossments or holes for secure connections, enabling the formation of very complex shapes for connecting electrical components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If busbars are made from punched and bent sheets, then manufacturing is relatively simple, but the ability to form complex three-dimensional line paths is limited

Engineering Contradiction:
Improveability to form complex three-dimensional line pathsVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent changes the fundamental geometric parameter of the conductor from flat sheet form to round wire form. This parameter change enables the conductor to be bent into complex three-dimensional paths while maintaining manufacturing feasibility through standard wire forming processes

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs curved and three-dimensional wire paths instead of flat bent sheets. The round cross-section of the wire allows it to be formed into complex curved paths in three-dimensional space, achieving the desired adaptability while remaining manufacturable

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Reliability

If contact areas are formed as flat embossments on the wire, then secure contact connections are achieved, but the contact area size is limited

Engineering Contradiction:
Improvecontact connection stabilityVSAvoidcontact area size
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent places additional contact surfaces within the三维 space created by the wire's curved path. Multiple contact areas can be positioned at different locations along the wire, effectively nesting multiple connection points within the overall wire structure, thereby increasing total contact area while maintaining compact form

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent transitions from two-dimensional flat contact areas to three-dimensional contact surfaces distributed along the curved wire path. This dimensional change allows contact areas to be positioned in multiple spatial locations, increasing the effective contact area available for connections

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The invention relates to a device (30) for connecting electrical components (20, 22) with a power supply (42). The invention is characterised in that the device (30) is formed by a three-dimensionally bent wire (32), in which contact regions (36) are formed at least at the ends thereof, and preferably also between same. In comparison to known devices that generate a connection with power rails or via contact plates, the device according to the invention is substantially easier and more cost-effective to produce and can be three-dimensionally deformed virtually as desired.
