Modular Foot Support System for Rehabilitation Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rehabilitation mechanisms for bedridden patients lack effective and secure methods for connecting and stabilizing the feet during automated gait therapy, particularly for unconscious patients who require additional stabilization due to their impairments.
Innovation Solution
A foot support system comprising an inner shell for receiving the foot, an outer shell for connection to the rehabilitation mechanism, and at least one strap for fixing the foot, with reversible connecting means that allow quick and secure attachment without the need for additional tools, providing stabilization and comfort during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional direct strapping of feet onto foot plate is used, then device complexity is reduced, but stabilization and securing of feet during movement is insufficient
Solution Approach 1:
The foot support system is divided into an inner shell that directly contacts the foot and an outer shell that connects to the foot module, allowing each component to be optimized for its specific function while maintaining overall stability without excessive complexity
Solution Approach 2:
The inner shell is nested within the outer shell, with the inner shell receiving the foot and the outer shell providing additional structural support and connection to the rehabilitation mechanism, creating a layered stabilization system
2Reliability
If simple direct strapping is used, then ease of operation is improved, but reliability of foot securing during movement deteriorates
Solution Approach 1:
The inner and outer shells are pre-configured with complementary connecting means (protrusions and recesses) that automatically align and engage when the foot is placed in the support system, eliminating the need for complex manual assembly while ensuring reliable foot securing
Solution Approach 2:
The connecting means are designed to self-align and self-lock when the foot is inserted, with the protrusion automatically fitting into the corresponding recess without requiring additional tools or complex manipulation by the operator
3Ease of operation
If reversible connecting means are implemented, then ease of operation is improved through quick attachment, but device complexity increases
Solution Approach 1:
The reversible connecting means are pre-configured with disengageable features that allow quick release through simple manual action, enabling rapid attachment and detachment of the foot support system without complex tools or procedures
Solution Approach 2:
The connecting means incorporate dynamic elements that transition between locked and unlocked states through simple manual manipulation, allowing the system to switch between secure attachment and easy detachment modes

AI summary
Disclosed is a foot support system for a foot module of a rehabilitation mechanism, the foot support system having an inner shell for receiving a person's foot, an outer shell for connection to a foot module of a rehabilitation mechanism, and at least one strap for fixing the foot to the foot support system. The inner shell, preferably on its side opposite a receiving region for the foot, has at least one connection for reversibly connecting the inner and outer shells, and wherein the outer shell, preferably at least on its side facing the inner shell when the inner shell and outer shell are connected, has at least one receiver corresponding to the at least one connection of the inner shell. By virtue of its modular set up, it permits simple, quick and comfortable connection to a foot module and advantageously protects and stabilizes the foot in particular during movement.
