Chiropractic Drop Section Lift Control for Comfortable Fluid Cocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current chiropractic tables with drop mechanisms require either time-consuming and labor-intensive manual operation or rapid, uncomfortable fluid actuators to raise the drop section for subsequent treatments, lacking a balanced and cost-effective solution for patient comfort.
Innovation Solution
A therapeutic treatment table equipped with a fluid actuator and a variable flow valve system to control the rate at which the drop section is raised, using a conventional fluid actuator for a controlled and comfortable cocking action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a manually-operated cocking device is used to raise the drop section, then the device is simple and inexpensive, but it is time-consuming and requires considerable effort from the practitioner
Solution Approach 1:
The patent applies a fluid actuator (pneumatic or hydraulic) to automatically raise the drop section, replacing the manual mechanical cocking device. The fluid actuator receives pressurized fluid through a control valve, which generates sufficient force to lift the drop section quickly and automatically, thereby reducing both the time required and the manual effort needed while maintaining system simplicity
2Ease of operation
If a fluid actuator is used to raise the drop section, then the operation is automated and quick, but the drop section rises too quickly causing patient discomfort
Solution Approach 1:
The patent employs a control valve that regulates the flow rate of pressurized fluid to the actuator, thereby controlling the speed at which the drop section rises. By adjusting the fluid flow parameters, the system achieves automated operation while preventing excessively rapid movement that would cause patient discomfort or alarm
3Object-affected harmful factors
If a motorized cocking device with gear train and eccentric linkage is used, then patient comfort is improved with gentle action, but the device becomes complicated and expensive
Solution Approach 1:
The patent replaces the complex motorized system with a simpler fluid actuator design. The fluid actuator, controlled by a regulated valve, provides sufficient force control to ensure patient comfort during the cocking operation, while eliminating the need for complex components such as gear trains, eccentric linkages, and motors, thereby reducing device complexity and cost
Applied Scientific Principles

Function Achieved in This Case
Provides a comfortable and efficient method to raise the drop section, balancing patient comfort with operational ease and using reliable, inexpensive components.
Implementation Method 1
a fluid actuator that is mounted between the frame and the body support and adapted to raise the body support from the lower position to the upper position
Implementation Method 2
means for controlling the flow of fluid to the fluid actuator in order to control the rate by which the fluid actuator raises the body support

AI summary
A therapeutic treatment table includes a frame and a table section for supporting at least a portion of the body of a patient. The table section includes a body support and a drop mechanism that is mounted between the frame and the body support and adapted to drop the body support from an upper position to a lower position. A fluid actuator is mounted between the frame and the body support and adapted to raise the body support from the lower position to the upper position, and a mechanism is provided for controlling the flow of fluid to the fluid actuator in order to control the rate by which the fluid actuator raises the body support from the lower position to the upper position.
