Passive Body Mobilization Device with PLC-Controlled Movable Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for body mobilization fail to effectively stimulate the abdominal and lumbar regions without physical effort, joint compression, or impact, while also addressing digestive and circulatory issues.
Innovation Solution
A passive body mobilization device with a bipartite structure and Programmable Logic Controller (PLC) that induces lateral flexion and extension movements, allowing for horizontal exercises without physical effort, using a movable platform to displace the body's axis and adjust user positioning for optimal comfort and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If passive body mobilization is achieved without physical effort, then ease of operation is improved, but effectiveness of muscle stimulation deteriorates
Solution Approach 1:
The device introduces an intermediary mechanical system (movable platform with lateral displacement capability) that mediates between the user's passive state and the desired therapeutic effect. The platform moves laterally to induce abdominal compression and relaxation, providing muscle stimulation without requiring the user to exert physical effort. This intermediary mechanism resolves the contradiction by decoupling the user's active participation from the effectiveness of the treatment.
Solution Approach 2:
The device transitions the exercise from the vertical dimension (traditional sit-ups and crunches requiring muscular effort) to the horizontal dimension (lateral platform movement). By moving the platform laterally rather than requiring vertical muscle contraction, the system achieves abdominal stimulation through a different dimensional approach, maintaining effectiveness while eliminating the need for physical effort from the user.
2Object-affected harmful factors
If horizontal movements are used to preserve articular bodies, then harmful factors are reduced, but range of motion deteriorates
Solution Approach 1:
The device segments the movement into two independent components: lateral platform displacement (horizontal motion for safety) and induced abdominal compression/relaxation (vertical effect for range). This segmentation allows the system to maintain the benefits of horizontal movement (reduced joint compression) while still achieving the necessary range of motion effects through the coupled abdominal mechanism.
Solution Approach 2:
The system compensates for the limited horizontal range of motion by introducing vertical dimension effects through abdominal compression and relaxation. The lateral platform movement creates a lever effect that amplifies the range of motion in the abdominal region without requiring large horizontal displacements, thus preserving joint safety while maintaining therapeutic effectiveness.
