Wall-Integrated Delivery Reception Device Using Nested Plate Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional delivery object reception devices protrude inward or outward from building walls, affecting the outer appearance and space utilization.
Innovation Solution
A delivery object reception device with plate-shaped members and turning units that allow for a seamless integration into the wall, featuring a rectangular opening with plate-shaped members that can turn to close or extend, forming a hexahedral storage space and using a transfer unit to move objects between members without protrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional reception container is mounted to a wall of a building, then the delivery object can be received, but the container protrudes inward or outward of the wall, which is unfavorable in terms of outer appearance or space
Solution Approach 1:
The reception container is nested within the wall structure itself, with the container body formed inside the wall thickness. The front surface of the container is flush with the outer wall surface, eliminating protrusion while maintaining the delivery reception function through the opening in the wall.
Solution Approach 2:
The invention utilizes the wall thickness dimension to house the reception container, transforming the problem from a two-dimensional wall surface to a three-dimensional wall volume solution. The container is positioned within the wall's depth rather than extending outward from its surface.
2Reliability
If the reception container is mounted to the wall, then delivery reception is enabled, but space utilization is reduced due to protrusion
Solution Approach 1:
The reception container is nested within the wall structure, utilizing the wall's internal volume rather than occupying external space. This nesting approach preserves the building's external dimensions and maximizes usable space while maintaining the delivery reception capability through the wall opening.
3Object-affected harmful factors
If plate-shaped members are turned to close the opening, then security and weather protection are improved, but the mechanism complexity increases
Solution Approach 1:
The plate-shaped members are designed as movable elements that can rotate between open and closed positions. This dynamic configuration allows the system to adapt to different operational states (receiving deliveries vs. protecting from elements) while using a relatively simple rotational mechanism rather than complex multi-stage systems.
