Lumbar Traction Massage Bed with Sliding Rail and Integrated Actuators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lumbar traction beds lack a massage function, failing to address muscle soreness in patients with lumbar disc prolapse and limiting their usability for household users.
Innovation Solution
A lumbar traction massage bed is designed with sliding and fixed end bed surfaces, equipped with massage portions for upper and lower limbs, and features an electric telescopic linear actuator for lumbar traction, along with a circuit board and controller for power and function control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lumbar traction beds are used solely for traction, then the traction function is achieved, but the massage function is lost and the device becomes unusable after traction
Solution Approach 1:
The patent combines the lumbar traction function and massage function into a single integrated bed system. The bed surface is designed to perform both traction (by creating separation between head and feet) and massage (through embedded massage portions that can be inflated/deflated), allowing one device to fulfill multiple therapeutic needs without requiring separate equipment
Solution Approach 2:
The bed is designed as a multi-functional device that can perform lumbar traction, full-body massage, and localized limb massage. The massage portions can be selectively activated for different body areas, and the bed structure allows both traction and massage operations to be performed independently or simultaneously, maximizing utility across different user needs
2Adaptability or versatility
If massage portions are added to the bed, then massage function is provided, but the device complexity increases
Solution Approach 1:
The bed is divided into distinct functional zones: a head portion, a foot portion, and multiple massage portions distributed along the bed surface. Each massage portion can be independently controlled and activated. The bed surface itself is segmented into a fixed end and a sliding end, allowing independent operation of traction and massage functions in different regions
Solution Approach 2:
The massage portions are embedded within or integrated into the bed surface structure, with massage bags or cushions nested within the bed framework. The circuit board and control systems are integrated into the bed structure, with wires routed through the bed frame to power and control the massage portions without adding external complexity

AI summary
The utility model applies to the field of medical apparatuses, and provides a lumbar traction massage bed. The lumbar traction massage bed includes a bed frame, and further includes a sliding end bed surface and a fixed end bed surface; the fixed end bed surface is fixed at one end of the bed frame, and the sliding end bed surface is connected to the other end of the bed frame in a sliding manner through a sliding rail; and massage portions are arranged at upper portions of both the sliding end bed surface and the fixed end bed surface. The user instructs a leg massage portion or an upper limb massage portion to massage his body through a controller, or the sliding end bed surface can be driven by a motor to move towards a direction away from the fixed end bed surface to achieve a lumbar traction function.
