Solution Overview

Problem

Existing translucent panel systems for portholes rely on external energy sources, such as electrical networks or batteries, which are exhaustible and may fail in case of breakdown, limiting their autonomy and requiring constant power supply adjustments for opacity control.

Innovation Solution

A translucent panel system incorporating a light energy sensor device with photovoltaic solar collectors and a battery system to harness and store energy, allowing partial or full autonomy by using luminous energy for power supply and opacity adjustment, with a polarizable film that adapts opacity based on power supply voltage, and an additional polarizable film for finer opacity control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external power supply (electrical network or battery) is used to power the polarizable film, then the opacity adjustment function is achieved, but the system loses autonomy and requires constant external energy input

Engineering Contradiction:
Improveautonomy of panel systemVSAvoidexternal energy dependency
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The panel system harvests light energy from the environment through photovoltaic sensors integrated into the transparent screen, enabling it to power its own polarizable film and control systems without continuous external energy input. The system serves itself by converting ambient light into electrical energy for autonomous operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system recovers light energy that would otherwise be wasted or unused by the structure, converting it into electrical power through photovoltaic conversion. This recovered energy is stored in batteries and used to power the polarizable film, transforming a discarded resource (ambient light) into a useful energy source.

Inventive Principle:
Principle #34Discarding and recovering

2Use of energy by moving object

If photovoltaic sensors are attached to the transparent screen, then energy is harvested for autonomous operation, but the transparency of the screen is reduced

Engineering Contradiction:
Improveenergy harvesting capabilityVSAvoidscreen transparency
Core Design Contradiction:
Use of energy by moving objectVSIllumination intensity

Solution Approach 1:

The photovoltaic sensors are selectively positioned and distributed across the transparent screen in specific patterns and densities, allowing different regions to have different properties. This enables energy harvesting in certain areas while maintaining transparency in critical viewing areas, optimizing both functions locally.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The transparent screen is constructed as a composite structure integrating photovoltaic sensor materials with transparent substrates. This composite approach allows the screen to simultaneously provide structural support, maintain optical transparency, and harvest solar energy through the embedded photovoltaic elements.

Inventive Principle:
Principle #40Composite materials

3Duration of action of moving object

If battery storage is used to store harvested energy, then autonomous operation during low light periods is enabled, but the device complexity increases

Engineering Contradiction:
Improveoperational duration without external powerVSAvoidpower management system complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The battery storage system is integrated and merged with the panel structure itself, combining the energy storage function with the existing architectural elements. This reduces the need for separate, additional components and simplifies the overall system architecture while maintaining autonomous operation capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The battery system serves multiple functions: storing harvested energy for later use, providing backup power during high-demand periods, and potentially serving as part of the structural or aesthetic design of the panel assembly. This multi-functionality reduces the need for dedicated single-purpose components.

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