Multi-layered Back Pad with Resistive Heating and Electrotherapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back therapy devices fail to provide effective and comfortable relief for back pain and injuries, as they either lack the combination of heat and electrotherapy or are not designed for supine use, leading to inadequate pain management and prolonged recovery times.
Innovation Solution
A multi-layered back pad with embedded resistive heating elements for heat therapy and electrotherapy electrodes for nerve and muscle stimulation, controlled by an external interface for customizable treatment, designed for use in a supine position to alleviate muscle tension and pain without the need for pain medication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pain relieving medication is used, then temporary pain relief is achieved, but dependence and further injury risk increase
Solution Approach 1:
The patent combines heat therapy and electrotherapy into a single integrated back pad device. The heating element provides thermal therapy to relax muscles, while electrodes deliver electrical stimulation to relieve pain and promote healing. This combination approach replaces medication with a non-invasive physical therapy solution that addresses both muscle tension and nerve pain simultaneously.
Solution Approach 2:
The back pad serves multiple therapeutic functions: it provides heat therapy through a heating element, electrotherapy through electrodes, and mechanical support through its contoured design. This multi-functional device replaces the need for separate treatment modalities and medication, offering comprehensive pain management in one apparatus.
2Reliability
If heat therapy is applied to relieve muscle tension, then pain relief is achieved, but the device must be comfortable for extended supine use
Solution Approach 1:
The back pad features a contoured design with a curved surface that matches the natural curvature of the human back. This ergonomic shaping allows the pad to conform to the spine and back muscles, distributing pressure evenly and providing comfort during extended supine use while maintaining effective contact with the therapeutic elements.
Solution Approach 2:
The pad is constructed from multiple layers including memory foam or orthopedic foam, which combines softness for comfort with structural support. This composite material structure provides both the comfort needed for extended use and the firmness required to maintain proper back alignment and effective heat/electrotherapy delivery.
3Reliability
If electrotherapy electrodes are embedded in the pad, then nerve stimulation and pain relief are achieved, but the device structure becomes more complex
Solution Approach 1:
The electrodes are integrated directly into the pad structure, merging the electrotherapy function with the support surface. This integration eliminates the need for separate electrode applications or additional complex wiring systems, as the electrodes become part of the pad itself that contacts the user's back during use.
Solution Approach 2:
The pad is designed to be self-contained with all therapeutic elements (heating element, electrodes, control circuitry) integrated into the single device. The pad serves itself by providing both mechanical support and therapeutic treatment simultaneously without requiring external equipment or complex assembly, simplifying the overall system.
4Reliability
If the pad provides firm support for proper posture, then back injury prevention is improved, but comfort for extended lying may be reduced
Solution Approach 1:
The pad uses multi-layer foam construction combining memory foam for contouring and pressure distribution with orthopedic foam for structural support. This composite structure provides both the firmness needed for proper posture maintenance and the softness required for comfort during extended supine use.
Solution Approach 2:
The contoured design with curved surfaces matches the natural anatomy of the back, allowing the pad to provide firm support to the spine and muscles while conforming to the body's shape. This curvature distribution ensures proper posture alignment without creating pressure points that would reduce comfort.
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 device provides effective pain relief and accelerates recovery by combining heat and electrotherapy in a comfortable and supportive structure, reducing the need for medication and promoting proper posture, making it suitable for home or travel use.
Implementation Method 1
a heat therapy means, whereby a resistive heating element provides a means of transferring heat into the user's back
Implementation Method 2
an electrotherapy means, whereby a plurality of electrodes are provided along an upper surface of the mat for applying a pulsating electrical current or pulses thereof to the user through direct skin contact

AI summary
A multi-layered therapy pad is provided having a comfortable and supportive structure that houses heat therapy and electrotherapy means for treating back injuries and sores while an individual lies thereon. The pad comprises a first and second outermost layer of low-resilience polyurethane foam sandwiching an internal layer of higher density foam, which also supports electrical connections between the therapy controller, the power source, and the two therapy means within the pad. The electrotherapy means comprises static or tethered electrodes that apply pulsing electric current directly onto the user's back for stimulation and easing of back pain, while the heat therapy is applied using a resistance heating element within the pad, which heats a majority of the pad for applying heat to the user's back. The operation of the therapy means is controlled by an external controller, while power in received through an external source or an internal battery pack.
