Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for unloading piece goods, particularly postal packages, are inefficient and time-consuming, often resulting in damage due to undesired movements and jamming during dumping.
Innovation Solution
A transport box equipped with a swing door tipping aid that can be locked and opened to control the unloading process, featuring a parallelogram motion retaining rod and a friction-reducing coating, allowing for controlled and accelerated unloading without blocking undesired movements, and a tarpaulin to prevent jamming and ensure smooth sliding of goods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closing device for the unloading opening is used, then the goods can be secured during transport, but the unloading process becomes time-consuming and complex
Solution Approach 1:
The closing system is divided into two independent components: a swing door for load securing during transport and a closing device (roller shutter or pivotable flap) for controlled unloading. The swing door can remain closed during unloading to maintain security, while the closing device provides the unloading function, allowing both functions to operate independently without interfering with each other.
Solution Approach 2:
The swing door acts as an intermediary element between the goods and the external environment. It provides continuous load securing while allowing the closing device to perform the unloading function separately. This intermediary structure enables simultaneous achievement of security and efficient unloading without requiring the entire closing system to be opened.
2Productivity
If the unloading opening is opened wide for fast unloading, then unloading speed increases, but goods may jam on the opening structure or locking device
Solution Approach 1:
The locking device is extracted from the path of the unloading opening by designing it with a parallelogram motion that retracts it into the wall thickness area when the opening is wide open. This allows the unloading opening to be fully opened for fast unloading while the locking device is positioned aside, eliminating the risk of goods jamming on it during the unloading process.
Solution Approach 2:
The locking device employs dynamic motion (parallelogram mechanism) that changes its position based on the opening state. When the unloading opening is closed, the locking device is in the locked position; when the opening is opened wide for unloading, the locking device automatically retracts into the wall thickness area, adapting its position to avoid interfering with the unloading flow.
3Reliability
If a locking device with protruding elements is used for securing the swing door, then the swing door can be reliably locked, but goods may hit the protruding elements during dumping
Solution Approach 1:
The locking device's protruding elements are extracted from the goods path by retracting them into the wall thickness area through the parallelogram motion mechanism. This allows the locking function to remain effective when needed while eliminating the harmful protruding elements that could damage goods during the unloading process.
Solution Approach 2:
The locking device transitions from a static protruding structure to a dynamic one that retracts and extends based on operational needs. During transport, the locking device protrudes to secure the swing door; during unloading, it retracts into the wall thickness area to avoid interfering with the goods flow, thus preventing damage while maintaining locking reliability.
4Extent of automation
If the swing door is made heavy for automatic opening, then opening automation improves, but control over opening speed becomes difficult
Solution Approach 1:
The opening speed parameter is made variable through the brake mechanism. The heavy swing door provides automatic opening force, while the brake allows operators to adjust and control the opening speed parameter as needed, transforming an uncontrollably fast automatic opening into a controllable process that can be adapted to different unloading requirements.
Solution Approach 2:
The brake mechanism provides feedback control on the swing door's opening motion. By applying braking force that can be modulated, the system responds to the heavy door's automatic opening tendency while allowing operators to regulate the speed, creating a feedback loop that balances automation with controllable speed.
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
The solution simplifies and accelerates the unloading process by allowing controlled tipping and separation of goods, reducing the risk of damage and jamming, while enabling efficient sorting and distribution by ensuring goods slide smoothly and are unloaded in a single layer.
Implementation Method 1
the locking device having a pivotable retaining rod, in particular for hooking the swinging door, with the retaining rod during a movement between the closed position and the open position essentially performing a parallelogram motion
Implementation Method 2
a friction-reducing coating
Implementation Method 3
the swing door can automatically swing open due to its own weight and/or due to the piece goods pressing against the swing door

AI summary
The box (10) has a housing (12) for accommodating packaged goods and comprising a base (32) for setting the packaged goods on the base. The housing comprises an unloading opening (34) for tipping of the packaged goods. A tipping unit e.g. foot element, covering plane and swinging door, is connected with the housing for enabling tipping motion of the packaged goods from the housing by the unloading opening. The covering plane is attached with the base of the housing, which comprises an excenter for clamping the plane between the excenter and the base of the housing.
