Solution Overview
Problem
Existing solutions for integrating unmanned aircraft delivery systems into building structures face issues with visual impairment, thermal insulation, and mechanical suitability for landings and take-offs, as well as limitations in installation on vertical walls and in reaching difficult locations.
Innovation Solution
A window or door element with a device for receiving and sending letters and parcels using unmanned aircraft, featuring a controlled outer and inner wing mechanism for improved thermal insulation, a telescopic pushing device for easier landing and take-off, and a design that integrates seamlessly with the building facade, maintaining aesthetic and thermal integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate receiving station with motorized closure and lifting device is installed on the roof, then delivery capability for unmanned aerial vehicles is achieved, but visual impact on the building envelope deteriorates and thermal insulation is compromised
Solution Approach 1:
The patent merges the drone delivery receiving function with the existing window structure. The window sash itself becomes the receiving platform, eliminating the need for separate receiving stations. This integration maintains building envelope aesthetics and thermal insulation while providing drone delivery capability.
Solution Approach 2:
The window sash is designed to serve multiple functions: it acts as both a conventional window component for light and ventilation, and as a receiving platform for unmanned aerial vehicles. This multi-functionality eliminates the need for dedicated delivery infrastructure that would compromise building aesthetics and thermal performance.
2Adaptability or versatility
If a window sash is designed to pivot horizontally to form a landing platform, then drone landing capability is achieved, but the mechanism is not ideally suited for landings and takeoffs
Solution Approach 1:
The patent employs a telescopic mechanism that dynamically adjusts the sash position. The sash can extend outward to create sufficient clearance for drone landings and takeoffs, then retract to maintain proper window sealing and insulation. This dynamic adjustment optimizes both operational reliability and thermal performance.
Solution Approach 2:
The window assembly is segmented into movable and fixed components. The sash can be independently positioned at different extensions, allowing optimization for different operational modes (drone delivery vs. conventional window function). This segmentation enables the mechanism to reliably support drone operations while maintaining building envelope integrity.
3Ease of operation
If both outer and inner sashes are opened simultaneously for ventilation, then ventilation effect is improved, but thermal insulation performance deteriorates
Solution Approach 1:
The patent implements a controlled sequence for sash operation. The outer sash opens first to allow ventilation, followed by the inner sash at a controlled interval. This periodic action maintains the thermal airlock longer, reducing heat loss while still providing effective ventilation when both sashes are open.
