Solution Overview

Problem

Existing systems that incorporate Peltier cells into paned doors and windows primarily assist in heating or cooling climate-controlled air, requiring external devices and not functioning independently for main climate control.

Innovation Solution

Integration of a plurality of Peltier cells into paned windows and doors, powered by an electrical circuit or photovoltaic panels, with reversible operation to manage heat transfer based on current direction, allowing for independent climate control by shaping the doors and windows to incorporate these cells within the frame and double glazing units, using heat sinks for efficient heat management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If Peltier cells are used as accessory elements for heating/cooling climate-controlled air, then the cells can provide thermal assistance, but the cells cannot perform main climate control independently

Engineering Contradiction:

Improveclimate control capabilityVSAvoidsystem independence

Core Design Contradiction:

Solution Approach 1:

The patent merges multiple Peltier cells into a single integrated window or door assembly, combining them with the glazing units and frame to create a unified climate control system that can independently regulate temperature without external assistance

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The window or door assembly is designed to perform multiple functions: the Peltier cells provide both heating and cooling capabilities, the double glazing units provide insulation, and the frame provides structural support, creating a multi-functional system that replaces separate climate control devices

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple Peltier cells are integrated into the frame and double glazing units, then independent climate control is achieved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The Peltier cells are nested within the frame structure and double glazing units, with the cells positioned between the glass panes or within the frame cavity, creating a compact integrated assembly where components are nested within each other to minimize space and simplify installation

Inventive Principle:

Principle #7Nested doll (Nesting)

3Temperature

Solution Approach 1:

The patent combines photovoltaic panels with the window or door assembly, merging the power generation function directly into the climate control system, allowing the cells to convert sunlight into electrical energy to power the Peltier cells and reduce dependence on external electrical supplies

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system converts sunlight, which can cause overheating, into useful electrical energy through photovoltaic panels, transforming a potential harmful effect (excessive heat and light) into a beneficial resource for powering the climate control function

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
