Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window sunshade systems either fail to maintain consistent indoor brightness and temperature or require manual operation, leading to increased energy costs and potential darkness when blocking sunlight.
Innovation Solution
A sunshade system with a frame unit, a sliding sunshade unit, a power transmission unit including a motor and drive gears, a washing brush for cleaning, and a control unit with sensors to automatically adjust sunlight interception and brightness, incorporating a solar panel and LED panel for energy efficiency and light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If curtains or blinds are installed to block sunlight, then indoor temperature control is improved, but indoor brightness deteriorates
Solution Approach 1:
The sunshade unit is divided into multiple segments that can be independently adjusted. Each segment can be positioned at different angles to control sunlight penetration, allowing selective blocking of thermal radiation while maintaining visual transparency and brightness in the indoor space.
Solution Approach 2:
The sunshade system employs dynamic adjustment capability where the sunshade unit can be automatically positioned based on real-time temperature and brightness sensor data. The system transitions from static coverage to dynamic control, adjusting the sunshade position and angle to optimize both temperature control and brightness maintenance throughout the day.
2Device complexity
If manual operation of curtains or blinds is used, then device complexity is reduced, but energy efficiency deteriorates
Solution Approach 1:
The system incorporates temperature sensors and brightness sensors that continuously monitor indoor conditions and provide feedback to the control unit. Based on this feedback, the control unit automatically adjusts the sunshade position and angle, eliminating the need for manual operation while optimizing energy efficiency by blocking sunlight when temperatures are high.
Solution Approach 2:
The sunshade system performs self-adjustment based on sensor feedback without requiring user intervention. The control unit autonomously determines the optimal sunshade position to maintain desired indoor temperature and brightness levels, making the system self-regulating and energy-efficient.
3Loss of energy
If solar panels are used for power generation, then energy efficiency is improved, but productivity deteriorates due to foreign material accumulation
Solution Approach 1:
The washing brush is designed to continuously clean the solar panel surface during the sunshade unit's movement. As the sunshade unit slides along the window, the attached washing brush continuously removes foreign materials from the solar panel, ensuring uninterrupted power generation efficiency without requiring separate cleaning operations.
Solution Approach 2:
The washing function is merged with the sunshade unit's movement mechanism. The washing brush is integrated onto the sunshade unit itself, combining the shading function and cleaning function into a single operational system. This eliminates the need for separate cleaning equipment and operations.
