Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load carrying platforms for garages require complex systems, sensors, and ceiling openings, leading to installation challenges, structural integrity issues, and risk of cable unwinding during descent.
Innovation Solution
A load carrying platform that travels vertically from underneath a ceiling to a floor using gravity for descent and a motor for ascent, with cables remaining under tension and not unwinding even when the motor is energized, and featuring adjustable legs for easy unloading and installation simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a motorized system is used to drive the platform both ascending and descending, then the platform can be precisely controlled, but the device complexity increases and requires sensors and complex ceiling mechanisms
Solution Approach 1:
Instead of using the motor to control both ascending and descending movements, the invention inverts the approach by using gravity for descending movement and the motor only for ascending movement. This eliminates the need for sensors and complex control systems while maintaining operational capability.
Solution Approach 2:
The platform uses its own weight (gravity) to perform the descending movement automatically without requiring motor control, sensors, or external intervention. The motor only needs to operate in one direction (ascending), significantly simplifying the control system.
2Ease of operation
If the platform is installed above the ceiling requiring an opening, then the platform can be positioned optimally, but the installation becomes complex and may affect structural integrity
Solution Approach 1:
The invention extracts the motor and control system from the ceiling area and relocates them to the platform itself. This eliminates the need for ceiling openings and complex installation while maintaining optimal positioning capability.
3Measurement precision
If sensors are used to stop the motor when descending is reached, then the platform can be precisely positioned, but the risk of cable unwinding increases in case of sensor failure
Solution Approach 1:
The invention converts the potential harm of uncontrolled descending into a benefit by using gravity as the driving force for descent. The platform descends automatically under gravity without requiring sensors to stop the motor, eliminating the risk of cable unwinding while maintaining positioning precision through mechanical means.
4Stability of the object's composition
If the platform rests parallel to the floor, then it is stable, but unloading bulky packages becomes difficult
Solution Approach 1:
The invention makes the platform dynamically adjustable by introducing legs that can change the platform's inclination angle. The platform can transition from a parallel (stable) position to a tilted (accessible) position, allowing easy unloading of bulky packages while maintaining stability when needed.

AI summary
A gravity descending and motorized ascending load carrying platform provides easy loading and installation underneath a ceiling. All mechanical and electrical components needed for operation of the platform travel with the platform. The mechanical components enable the platform to descend/ascend parallel to the floor, to hover parallel and over the floor when the platform supporting legs remain stored within its structure, to tilt when the cables on one side of the platform are under zero gravity force while the cables on the other side are still subjected to gravity force, to hover in a tilted position over the floor if the short supporting legs are not in contact with the floor while its long supporting legs are, to rest on its supporting legs whether in a position parallel to the floor or in a position forming a slope with the floor.
