Low Humidity Joint Therapy Appliance with Desiccant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for arthritis pain do not effectively provide a self-contained, passive therapy solution that can be used independently of external power sources and are not easily integrated into daily activities.
Innovation Solution
A self-contained appliance comprising a moisture impermeable barrier material forming a therapy region around a bone joint, with a desiccative agent like silica gel between the impermeable barrier and a moisture permeable inner liner, allowing for a low-humidity environment that reduces joint moisture and discomfort, and can be secured using closure elements like zippers or hook-and-loop fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a moisture impermeable barrier material is used to create a therapy region, then the low-humidity environment is maintained effectively, but the comfort and breathability for the user deteriorates
Solution Approach 1:
The patent applies different material properties to different regions: the outer shell uses moisture impermeable barrier material for reliable humidity control, while the inner liner uses moisture permeable material for comfort and breathability. This local differentiation resolves the contradiction between reliability and user comfort.
Solution Approach 2:
The patent combines moisture impermeable barrier material and moisture permeable material in a composite structure. The impermeable outer layer maintains the low-humidity environment while the permeable inner layer provides breathability and comfort, resolving the contradiction between these opposing requirements.
2Reliability
If a desiccative agent is placed within the therapy region, then the arthritis pain relief effectiveness improves, but the device complexity increases
Solution Approach 1:
The patent merges the desiccative agent storage function with the structural design of the appliance by incorporating storage compartments into the body encompassing element. This integration reduces overall device complexity while maintaining effective arthritis pain relief.
Solution Approach 2:
The patent nests the desiccative agent within compartments formed by the body encompassing element structure. The desiccative agent is contained within the therapy region through integrated compartments, simplifying the overall device architecture while ensuring effective moisture control for pain relief.
3Reliability
If closure elements are added to secure the appliance about the body limb, then the therapy region isolation from external environment improves, but the ease of application and removal deteriorates
Solution Approach 1:
The patent employs dynamic closure elements such as zippers or hook-and-loop fasteners that can be easily engaged and disengaged. These closure mechanisms provide reliable isolation when closed but allow quick application and removal when opened, resolving the contradiction between isolation reliability and operational ease.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The appliance effectively reduces arthritis pain by creating a low-humidity environment around the joint, allowing for continued use during normal activities without the need for external power, and is simple, safe, and cost-effective.
Implementation Method 1
a desiccative agent disposed within the therapy region
Implementation Method 2
a bone joint encompassing element formed of a moisture impermeable barrier material
Implementation Method 3
The inner liner is attached to the moisture impermeable barrier material to form one or more compartments to accommodate the desiccant agent
