Solution Overview

Problem

Existing door handle electronic modules lack integrated lighting solutions and are not adequately protected from external environmental influences, leading to separate structural components and reduced functionality.

Innovation Solution

An electronic module with a conductor element hosting electrical components and a directly integrated lighting means, protected by a light cap that allows light emission while shielding from external influences, forming a compact and cost-effective unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the electronic module is completely encapsulated with potting compound to protect from environmental influences, then protection against moisture and dust is improved, but lighting functionality is lost

Engineering Contradiction:
Improveprotection against moisture and dustVSAvoidlighting functionality
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The electronic module is divided into two zones: a first region that is completely encapsulated with potting compound for protection against environmental influences, and a second region that remains accessible for integrating lighting elements. This segmentation allows simultaneous achievement of both protection and lighting functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the electronic module are assigned different levels of protection and functionality. The first region receives full encapsulation for environmental protection, while the second region is left accessible to accommodate lighting elements, creating local quality variations that satisfy conflicting requirements.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If the lighting element is connected externally via electrical supply lines and plugs, then lighting functionality is achieved, but structural complexity increases

Engineering Contradiction:
Improvelighting functionalityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lighting element is integrated directly into the electronic module structure, merging previously separate components (electronic module, electrical connections, lighting element) into a single unified structure. This eliminates the need for external electrical supply lines and plugs, reducing structural complexity while maintaining lighting functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The electronic module is designed to serve multiple functions: it provides electronic control functions and simultaneously houses the lighting element with integrated electrical connections. This multi-functionality eliminates the need for separate external lighting components and their associated wiring.

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

3Device complexity

If the lighting element is integrated directly into the electronic module, then structural complexity is reduced, but protection from environmental influences is compromised

Engineering Contradiction:
Improvestructural complexityVSAvoidprotection against environmental influences
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The electronic module is segmented into a protected first region (encapsulated with potting compound) and an accessible second region (housing the lighting element). This segmentation allows the lighting element to be integrated into the module structure while still providing environmental protection through the encapsulation of critical electronic components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the integrated electronic module receive different levels of environmental protection. The first region with sensitive electronic components is fully encapsulated, while the second region containing the lighting element is left accessible, creating local quality variations that balance protection and integration.

Inventive Principle:
Principle #3Local quality
