Solution Overview

Problem

Existing photoelectric monitoring systems in vehicles face challenges in being discreetly located while maintaining a good line of sight, and there is a need for systems that can be easily deployed in different vehicle types and provide 3D mapping of spaces inside and outside vehicles.

Innovation Solution

A monitoring system with photoelectric sensor elements integrated into a transparent laminate structure, comprising a carrier layer between two transparent layers, allowing sensors to be spread across a large surface for optimal positioning and 3D mapping, using triangulation, structured light, or time-of-flight methods, with flexible wiring for power and signal distribution, and embedded or mounted sensors for thinness and imperceptibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If photoelectric sensor systems are integrated into vehicle interiors, then monitoring functionality and driver assistance are improved, but the systems become visible and less discrete

Engineering Contradiction:
Improvemonitoring functionalityVSAvoidvisibility of system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the photoelectric sensor system with the vehicle's window glass by integrating sensor elements into the laminate structure of the glass. This combination allows the monitoring system to be embedded within the existing transparent component, making it invisible while maintaining full functionality for driver assistance and space monitoring.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transparent carrier layer and laminate structure serve as an intermediary medium that houses the sensor elements. This intermediary structure allows the sensors to be positioned within the glass layers, using the glass itself as the mounting substrate and providing both structural support and optical transparency.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If sensor systems are positioned for optimal line of sight, then monitoring precision is improved, but the systems become less adaptable to different vehicle types

Engineering Contradiction:
Improveline of sightVSAvoiddeployment in different vehicle types
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal sensor system that can be deployed across different vehicle types by integrating sensors into the window glass, which is a common component across various vehicle models. The system can monitor both interior and exterior spaces, providing multi-functional capability that adapts to different vehicle configurations without requiring custom positioning for each vehicle type.

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

Solution Approach 2:

The patent transitions from traditional two-dimensional sensor placement on surfaces to three-dimensional integration within the laminate structure of the glass. This dimensional change allows sensors to be positioned at multiple depths and angles within the glass layers, providing optimal line of sight while maintaining adaptability to different vehicle geometries.

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

3Measurement precision

If multiple sensor elements are distributed across large surfaces, then 3D mapping capability is improved, but the number of components and wiring complexity increases

Engineering Contradiction:
Improve3D mapping capabilityVSAvoidwiring and component distribution
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple sensor elements, conductor layers, and protective layers into a single integrated laminate structure. The conductor layers are embedded within the laminate, eliminating the need for separate wiring harnesses and reducing the complexity of connecting distributed sensor elements across large glass surfaces.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transparent carrier layer and laminate structure serve as an intermediary substrate that provides both mechanical support and electrical connectivity pathways. The conductor layers embedded in the laminate act as intermediaries for signal transmission between distributed sensors, reducing the need for complex external wiring.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Illumination intensity

If sensors are embedded in the laminate structure, then transparency and aesthetics are improved, but the manufacturing process becomes more complex

Engineering Contradiction:
ImprovetransparencyVSAvoidmanufacturing process
Core Design Contradiction:
Illumination intensityVSEase of manufacture

Solution Approach 1:

The patent incorporates sensor elements and conductor layers into the laminate structure during the glass manufacturing process, before the final product is assembled. This preliminary integration allows sensors to be embedded within the glass layers themselves, maintaining transparency while avoiding complex post-manufacturing assembly steps.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses composite laminate materials that combine transparent glass layers with embedded conductor layers and sensor elements. This composite structure maintains the optical properties of glass while integrating functional components, achieving both transparency and sensor functionality through material composition rather than surface mounting.

Inventive Principle:
Principle #40Composite materials
