Receiving and pick-up device for postal items and corresponding method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing postal delivery systems for detached houses and apartment buildings lack flexibility in receiving and picking up various-sized postal items without the recipient's presence, often requiring manual adjustment and occupying excessive space.
Innovation Solution
A receiving and pick-up device with a multi-part housing that adjusts volume via a telescopic mechanism, featuring a closable exterior and interior opening, and an automated adjustment system, allowing flexible adaptation to item size and enabling unmanned aerial vehicle access, with electronic components for autonomous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the receiving chamber volume is increased to accommodate various-sized postal items, then the adaptability is improved, but the space occupancy increases
Solution Approach 1:
The receiving chamber is designed with a telescopic mechanism that allows dynamic adjustment of its volume. The extension part can be moved along the adjustment axis between different positions (first position for smaller volume, second position for larger volume) to adapt to different postal item sizes. This dynamic adjustment enables the device to provide a large receiving chamber when needed while maintaining a compact form when not in use, thereby resolving the contradiction between adaptability and space occupancy.
2Device complexity
If manual adjustment of the receiving chamber is required, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The adjustment device is designed to automatically adjust the volume of the receiving chamber based on the size of the postal item to be received. The system performs the adjustment function autonomously without requiring manual intervention from the user, thereby improving ease of operation while maintaining relatively simple structural complexity.
3Ease of operation
If the receiving chamber is accessible from the exterior, then the ease of operation is improved, but the reliability deteriorates due to security risks
Solution Approach 1:
The receiving chamber is segmented into two distinct openings: a first opening accessible from the exterior and a second opening accessible from the interior. The housing is divided into a base part and an extension part that can be adjusted relative to each other. This segmentation allows the exterior opening to remain secure while still enabling easy access for depositing items, as the extension part can be adjusted to provide access through the appropriate opening based on the delivery scenario.
