Solution Overview
Problem
Current treatments for musculoskeletal conditions such as osteoarthritis and ACL injuries, including physical therapy and bracing, face challenges with compliance and sustainability, leading to inadequate muscle strength recovery and increased re-injury risk.
Innovation Solution
Cutaneous stimulation devices with active or passive modules that apply tactile stimuli, such as pressure, vibration, or thermal changes, to specific skin locations, designed to be easily applied, customizable, and cost-effective, to enhance muscle activation and rehabilitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If complex clinic-based rehabilitation programs are used to strengthen quadriceps, then muscle strength improvement is achieved, but compliance and adherence rates deteriorate
Solution Approach 1:
The patent replaces complex mechanical rehabilitation equipment and clinic-based programs with a cutaneous stimulation device that uses tactile stimuli (pressure, vibration, thermal changes) to activate muscle contraction. This substitution maintains muscle strengthening effectiveness while eliminating the need for complex machinery and extensive therapist involvement, thereby improving compliance.
Solution Approach 2:
The device enables patients to perform rehabilitation at home without requiring constant therapist supervision or complex equipment operation. The stimulation module automatically delivers therapeutic stimuli when applied to the skin, allowing patients to independently maintain quadriceps strength, thus improving adherence to the rehabilitation program.
2Strength
If aggressive rehabilitation programs are implemented following ACL injury, then quadriceps function improvement is attempted, but re-injury risk remains high due to sustained muscle weakness
Solution Approach 1:
The cutaneous stimulation device is applied early in the rehabilitation process following ACL injury to prevent quadriceps atrophy before it becomes severe. By providing continuous or periodic tactile stimulation that maintains muscle activation, the device proactively prevents muscle weakness that would otherwise lead to re-injury, rather than attempting to reverse established weakness.
Solution Approach 2:
The device provides ongoing muscle stimulation throughout the rehabilitation period, ensuring continuous maintenance of quadriceps function. This continuous action prevents the cycles of weakness and strengthening that characterize traditional rehabilitation, thereby more reliably reducing re-injury risk associated with sustained muscle weakness.
3Stability of the object's composition
If traditional treatments such as braces and elastic wraps are used, then joint stability is improved, but compliance deteriorates due to discomfort and obtrusiveness
Solution Approach 1:
The patent replaces mechanical braces and elastic wraps with a cutaneous stimulation system that uses sensory input (tactile stimuli) to influence muscle activation and joint stabilization. This substitution eliminates the physical discomfort and obtrusiveness of traditional devices while maintaining joint stability through neuromuscular control, thereby improving compliance.
4Ease of operation
If low profile, easily applied devices are designed, then ease of operation improves, but treatment effectiveness may deteriorate
Solution Approach 1:
The patent achieves both ease of application and treatment effectiveness by substituting complex mechanical delivery systems with a sensory-based approach. The cutaneous stimulation module can be simply applied to the skin surface yet delivers effective muscle activation through tactile stimuli, demonstrating that simplified application does not compromise therapeutic outcome.
