Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heavy object supporting devices require external fluid supply to maintain hydraulic pressure, which can be cumbersome and not easily usable in certain environments.
Innovation Solution
A heavy object supporting device with a mounting table, a base forming a gap, an elastic annular sealing member between them, and a separation preventing structure to maintain a fluid-filled space, allowing pressure generation and maintenance without external fluid supply, using the elastic member to compress and regulate movement between the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external fluid supply means and control devices are provided to maintain hydraulic pressure, then the heavy object can be supported, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The heavy object supporting device utilizes its own weight to automatically generate and maintain hydraulic pressure in the hydraulic pocket. When the heavy object is placed on the mounting table, its weight compresses the elastic ring, which in turn pressurizes the hydraulic fluid within the sealed pocket. This self-service mechanism eliminates the need for external fluid supply means and control devices, thereby reducing device complexity while maintaining the ability to support heavy objects.
2Reliability
If external fluid supply means and control devices are provided to maintain hydraulic pressure, then the heavy object can be supported, but the ease of operation deteriorates
Solution Approach 1:
The device automatically generates hydraulic pressure through the weight of the heavy object itself, requiring no manual operation for fluid supply or pressure control. The elastic ring and hydraulic pocket system self-regulate based on the load, making the device extremely easy to operate - simply place the heavy object on the mounting table and the supporting mechanism activates automatically.
3Stress or pressure
If the hydraulic pressure is generated by supplying oil from outside, then the heavy object can be supported, but the structure becomes more complex
Solution Approach 1:
The invention extracts and eliminates the external fluid supply system and control devices from the heavy object supporting device. Instead of requiring external oil supply passages and control mechanisms, the design uses the heavy object's own weight to generate hydraulic pressure internally through the elastic ring and hydraulic pocket, achieving pressure generation without external components.
Solution Approach 2:
The hydraulic pressure generation system serves itself by using the heavy object's weight as the power source. The elastic ring, positioned between the mounting table and the base, is compressed by the heavy object's weight, which automatically pressurizes the hydraulic fluid in the sealed pocket without requiring external fluid supply or control mechanisms.

Function Achieved in This Case
Enables the generation and maintenance of pressure to support heavy objects within the device without external fluid supply, simplifying the structure and preventing fluid leakage or air entry, thus enhancing usability and reducing the need for external control systems.
Implementation Method 1
the at least one sealing member being formed to support the mounting table to form a gap between the mounting table and the base, and is formed to be able to be compressed to reduce the gap between the mounting table and the base
Implementation Method 2
a space, which is formed between the mounting table and the base and surrounded by the at least one sealing member, being formed as a fluid-filled space that is sealed in a state filled with fluid

AI summary
A heavy object supporting device includes: a mounting table which is arranged to face a base, and on which a supported object is mounted; an annular sealing member which is arranged between the mounting table and the base and can be elastically compressed in the direction in which the mounting table and the base face each other; and a separation preventing structure which prevents separation between the mounting table and the base. A space, which is defined by the mounting table, the base, and the sealing member, is formed as a fluid-filled space that is sealed in a state filled with fluid. The separation preventing structure is configured to allow the mounting table to be moved relative to the base in the facing direction and the direction orthogonal to the facing direction while maintaining the sealed state of the fluid-filled space.
