Creeping Motion Therapy Linkage for Coordinated Infant Crawling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing therapy devices fail to provide coordinated movement of both arms and legs simultaneously in a creeping or crawling motion, which is essential for promoting proper muscle development in infants.
Innovation Solution
A motor-driven therapy device with slidable paddles and leg supports, coupled through a linkage assembly to a flywheel system, mimics a creeping motion by alternately moving right and left paddles and leg supports in unison, replicating natural infant crawling motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing therapy devices are used, then limb movement is provided, but coordinated movement of both arms and legs in creeping motion is not achieved
Solution Approach 1:
The device is divided into separate modular components including right and left paddles, right and left leg supports, a flywheel assembly, and a linkage assembly. Each component can be independently designed, adjusted, and maintained, while working together to produce coordinated creeping motion through the linkage mechanisms that connect them.
Solution Approach 2:
The linkage assembly acts as an intermediary mechanism between the motor-driven flywheel and the paddles/leg supports. It translates rotational motion into coordinated alternating linear motion of the right and left limbs, enabling the creeping pattern without requiring direct complex control of each limb individually.
2Reliability
If coordinated creeping motion is implemented, then therapeutic effectiveness is improved, but device complexity increases
Solution Approach 1:
The device implements periodic alternating motion where the right paddle and left leg support move forward while the left paddle and right leg support move backward, then reverse. This periodic reciprocating motion through the linkage assembly reliably produces the therapeutic creeping pattern essential for infant muscle development.
Solution Approach 2:
The sliding connections between the linkage assembly and the paddles/leg supports allow for adjustable motion parameters such as stroke length, speed, and amplitude. These parameter changes enable customization of the creeping motion to match different infant developmental stages and therapeutic requirements while maintaining mechanical simplicity.

AI summary
A creeping motion therapy device promotes proper crawling and includes a motor coupled to a frame. Each of a right paddle and a left paddle are coupled to and slidable relative to the frame. Right and left leg supports are also coupled to and slidable relative to the frame. A linkage assembly is mechanically coupled to a main flywheel assembly mechanically coupled to the motor. Each of the right paddle, the left paddle, the right leg support, and the left leg support is mechanically coupled to the linkage assembly such that the right paddle and the left leg support move alternately backward and forward in unison and the left paddle and the right leg support move in unison in opposite to the right paddle and the left leg support wherein the right paddle, left paddle, right leg support, and left leg support mimic a creeping motion.
