Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Duplex windows experience reduced heat insulating gas over time due to minute gaps and permeation, leading to deteriorated performance, and architectural glass is difficult for robots to recognize due to its reflective and refractive properties.
Innovation Solution
A window system with a gas duct and gas managing unit that allows communication between the gas space and the outside, using carbon dioxide as a detectable gas that can be injected and monitored by a robot's infrared sensor, enhancing recognition and maintaining heat insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a heat insulating layer filled with inert gas is formed between transparent plates, then heat insulating effect is improved, but heat insulating gas is lost over time through minute gaps and permeation
Solution Approach 1:
The gas managing unit enables the heat insulating gas to replenish itself automatically. When gas is lost through permeation or gaps, the managing unit detects the pressure change and injects new gas to maintain the required pressure, allowing the system to self-correct and maintain its heat insulating properties over time without manual intervention
Solution Approach 2:
The gas managing unit incorporates a feedback mechanism by monitoring the internal pressure of the sealed space and automatically responding when gas loss is detected. The unit compares the actual pressure against the target pressure and activates the gas injection system only when needed, optimizing gas retention while preventing unnecessary gas loss
2Illumination intensity
If transparent plates are used for the window, then visibility is improved, but robot recognition is worsened due to light reflection and refraction
Solution Approach 1:
The patent utilizes infrared-absorbing gas (carbon dioxide) that interacts with infrared radiation in a detectable manner. While the visible transparency of the glass plates is maintained for human visibility, the presence of CO2 creates a detectable infrared signature that robots equipped with infrared sensors can recognize, effectively adding a detection layer without compromising visual transparency
Solution Approach 2:
The heat insulating gas serves as an intermediary that provides dual functionality: it maintains thermal insulation between the transparent plates while simultaneously acting as an infrared-detectable marker. This intermediary substance enables robot detection without requiring changes to the transparent plates themselves, preserving visibility while adding recognition capability
3Reliability
If a gas duct and gas managing unit are added, then gas replenishment is improved, but device complexity is worsened
Solution Approach 1:
The gas managing unit is designed to perform multiple functions within a single integrated device: it monitors pressure, controls gas injection, and maintains the heat insulating properties. By combining these functions into one unit rather than separate systems, the patent reduces overall complexity while ensuring reliable gas space maintenance
Solution Approach 2:
The gas duct and managing unit are pre-installed within the window structure during manufacturing, with the gas injection system ready for immediate operation. This preliminary preparation ensures that when gas loss occurs, the replenishment process can begin immediately without requiring additional installation steps, maintaining reliability while managing complexity through advance planning
