Swing Seat Plate Lowering Mechanism for Horizontal Load Descent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to ensure that objects are lowered from a pedestal in a horizontal or near-horizontal state, potentially causing damage and increased burden due to inclination.
Innovation Solution
An object lowering device featuring a swing mechanism with a seat plate that tilts on a pedestal, utilizing airbags for impact absorption, beam raising mechanisms, and locking mechanisms to maintain a horizontal or near-horizontal position during descent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pedestal is lowered directly without tilting, then the lowering process is simple, but the object cannot be lowered in a horizontal state causing damage and increased burden
Solution Approach 1:
The pedestal is designed to dynamically tilt along a predetermined trajectory during lowering, transforming from a static vertical lowering process to a dynamic controlled tilting process. This allows the seat plate to maintain horizontal orientation while the pedestal angle changes, resolving the contradiction between simple lowering and horizontal object placement.
Solution Approach 2:
The tilting action is performed preliminarily during the lowering process before the object contacts the ground. By pre-tilting the pedestal along a calculated trajectory, the system ensures the object arrives in horizontal state, preventing damage and burden before they occur.
2Object-affected harmful factors
If a swing mechanism is added to maintain horizontal state, then object damage is reduced, but the device complexity increases
Solution Approach 1:
The swing mechanism serves multiple functions: it acts as both a lowering mechanism and a leveling mechanism simultaneously. The swing's natural arc motion provides both the descent function and the horizontal stabilization function, eliminating the need for separate complex leveling systems.
Solution Approach 2:
The system changes the swing angle parameter during lowering to maintain the seat plate in horizontal orientation. By dynamically adjusting the swing angle along a predetermined trajectory, the mechanism achieves horizontal object placement without requiring complex active control systems.
3Productivity
If the seat plate is lowered quickly, then productivity is improved, but impact forces increase causing damage
Solution Approach 1:
Airbags are deployed in advance before the seat plate contacts the ground to provide cushioning. This preliminary cushioning measure allows faster lowering speeds while preventing impact damage, as the airbags absorb the shock upon contact.
Solution Approach 2:
The airbag system uses pneumatic principles to provide impact absorption. The inflatable airbags create a compliant cushioning layer that dissipates impact energy, enabling high-speed lowering without damage to the object or structure.

AI summary
The object lowering device comprises a pedestal and a swing. The swing includes a seat plate on which an object is placed, and is disposed on the pedestal. The pedestal is tilted with the lower corner of one side in the swinging direction of the pedestal as an axis, and the seat plate of the swing moves down to the ground, whereby the object is lowered to the ground.
