Solution Overview

Problem

Existing membrane technologies face challenges in electrical contacting, which often require openings in the laminate structure, altering the membrane properties and complicating manufacturing processes.

Innovation Solution

Integration of a conductive insert within the membrane layers, using conductive particles or linear lines, allows for electrical connection without openings, maintaining membrane properties and simplifying production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If openings are made in the laminate structure for electrical contacting, then electrical connection is achieved, but the membrane properties are altered and manufacturing is complicated

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent merges the electrical circuit with the membrane structure by integrating conductive inserts directly into the laminate layers. The conductive insert consists of conductive particles embedded within the membrane material itself, combining the electrical conduction function with the structural membrane function, thereby eliminating the need for separate openings that would compromise membrane integrity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent employs composite materials by incorporating conductive particles (such as carbonaceous material) into the elastomeric layers of the membrane. This creates a composite structure where the base membrane material provides mechanical properties while the embedded conductive particles provide electrical conductivity, achieving both functions within a unified material system without requiring openings.

Inventive Principle:
Principle #40Composite materials
