Door and package receiving assembly combination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door systems lack a secure and efficient mechanism for receiving packages without compromising security or aesthetics, particularly in residential and office settings.
Innovation Solution
A door with a package pass-through mechanism featuring a pivotally coupled lower panel that forms a chute for sliding packages and a slidably attached closing panel, linked by a mechanism that adjusts between closed and open positions to allow package delivery while maintaining security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a package pass-through mechanism is added to the door, then package delivery efficiency is improved, but device complexity increases
Solution Approach 1:
The closing panel is nested within the door structure, sliding into a recessed area when in the closed position. This integration allows the package receiving mechanism to be embedded within the door's existing form factor, adding functionality without substantially increasing external dimensions or visual complexity.
Solution Approach 2:
The lower panel is designed to be dynamically reconfigurable between a first position (flush with the door) and a second position (angled to form a chute). This dynamic transformation allows the same structural element to serve multiple functions: maintaining door integrity when not in use and enabling package delivery when activated, thereby improving efficiency without permanently increasing complexity.
2Ease of operation
If the lower panel is angled to form a chute, then package sliding capability is improved, but security is worsened
Solution Approach 1:
The closing panel is positioned in advance to cover the opening before the lower panel is angled to form the chute. This preliminary action ensures that the opening is already secured when the package receiving configuration is activated, preventing unauthorized access while maintaining package sliding capability.
Solution Approach 2:
The closing panel acts as an intermediary element between the opening and the external environment. When positioned in the closed position, it mediates by blocking direct access to the opening while still allowing the lower panel to be angled for package insertion, thus maintaining security during the package receiving operation.
3Reliability
If the closing panel covers the opening, then security is improved, but package access is worsened
Solution Approach 1:
The lower panel's ability to rotate between positions enables the system to dynamically switch between security mode (flush position) and package access mode (angled position). This dynamic reconfiguration allows the closing panel to maintain security coverage while still permitting package insertion through the angled chute configuration.
Solution Approach 2:
The door covering is segmented into multiple independent panels: the closing panel that provides security coverage and the lower panel that can be independently angled for package access. This segmentation allows each panel to perform its specific function without interfering with the other, maintaining security while enabling package access.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure and efficient package delivery by allowing packages to be slid through the door without compromising security or the door's appearance, ensuring that the package can be received without unauthorized access.
Implementation Method 1
The lower panel is angled to form a chute for sliding packages down the lower panel and through the opening

AI summary
A door and package receiving assembly combination includes a door having an opening extending therethrough. A covering is attached to the door and closes the opening. The covering includes a lower panel pivotally coupled to the door that is positionable in vertical position covering the opening or in an angled position exposing the opening. The lower panel forms a chute for sliding packages down the lower panel and through the opening. A closing panel is attached to the door and is downwardly moved to closed position covering the opening or upwardly moved to an open position exposing the opening. A linkage is attached to the closing panel and the lower panel. The linkage lowers the closing panel to the closed position as the lower panel is moved to the angled position and lifts the closing panel to the open position as the lower panel is moved to the vertical position.
