Solution Overview

Problem

The production of laminated panes with customer-specific and application-specific connection regions for electrical contacting of ribbon cables is resource-intensive and expensive, requiring adaptation for each customer and application, especially for connecting to round cables which are more cost-effective.

Innovation Solution

A connection assembly comprising a laminated pane with a ribbon cable that has a first connection region between the panes and a second connection region outside the pane, with electrical conductor tracks arranged in multiple planes for flexible and cost-effective electrical contacting of the ribbon cable to a control system, allowing easy lamination and handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If customer-specific and application-specific connection regions are produced for each customer and application, then the electrical contacting of ribbon cables is adapted to specific requirements, but the production becomes resource-intensive and expensive

Engineering Contradiction:
Improveadaptability of connection regionVSAvoidproduction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies universality by creating a standardized connection region design that can serve multiple customers and applications. Instead of producing custom connection regions for each customer, the invention uses a universal connection region structure that accommodates different ribbon cable configurations through standardized opening shapes (rectangular, U-shaped, or annular) and positioning, thereby maintaining adaptability while significantly improving production efficiency

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The connection region is segmented into standardized geometric shapes (rectangular, U-shaped, annular) that can be universally applied. This segmentation allows the same basic structure to serve different purposes by simply changing the opening configuration, eliminating the need for completely custom designs for each application while maintaining the required adaptability

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If thin flat conductors are used to embed in thermoplastic adhesive layer, then the electrical connection is achieved, but the total thickness is limited to at most 0.3 mm

Engineering Contradiction:
Improveease of embeddingVSAvoidthickness of conductor
Core Design Contradiction:
Ease of manufactureVSLength of stationary object

Solution Approach 1:

The patent transitions from using thin flat conductors (2D plane) to using a layered structure with conductor layers on both sides of the electro-optical component (3D space). This dimensional change allows the effective conductor thickness to exceed 0.3 mm by stacking conductive layers separated by the electro-optical component, while still maintaining ease of embedding within the thermoplastic adhesive layer

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

3Adaptability or versatility

If ribbon cables are used for complex control tasks, then multiple electrical conductor tracks are provided, but the handling and connection to round cables becomes more difficult

Engineering Contradiction:
Improveelectrical contacting capabilityVSAvoidhandling ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces an intermediary connection structure at the connection region that facilitates the transition from ribbon cable to round cable. The standardized opening in the support structure serves as a mediator that simplifies the connection process, allowing multiple conductor tracks to be routed through a single standardized opening while maintaining ease of handling and connection to round cables

Inventive Principle:
Principle #24Intermediary (Mediator)
