Implantable Joint Heating Control for Cold and Arthritis Pain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implantable joints lack the capability to provide warmth and temperature regulation, leading to discomfort and pain due to cold, arthritis, or other environmental conditions.
Innovation Solution
Implantable joints with a heating system that includes a controller, temperature sensor, and heating elements, which apply heat when a lower temperature limit is sensed and discontinue heating when an upper limit is reached, using a wirelessly rechargeable power source or a hybrid approach combining on-board and external power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a heating system is added to the implantable joint, then patient comfort and pain relief are improved, but device complexity increases
Solution Approach 1:
The heating element, temperature sensor, controller, and power source are integrated into a single implantable joint device, combining multiple functional components into one unified system that provides thermal regulation without requiring separate implanted devices
Solution Approach 2:
The temperature sensor continuously monitors the joint temperature and provides feedback to the controller, which automatically activates the heating element when the temperature drops below a threshold, creating a self-regulating thermal control system that operates autonomously
2Temperature
If a heating element is included in the implantable joint, then warmth and comfort are improved, but power consumption increases
Solution Approach 1:
The heating element operates intermittently rather than continuously, activating only when the temperature sensor detects that the joint temperature has dropped below a predetermined threshold, and deactivating when the upper temperature limit is reached, thereby reducing overall power consumption
Solution Approach 2:
The temperature sensor provides continuous feedback to the controller about the joint temperature, enabling the system to activate heating only when necessary and maintain temperature within a target range, optimizing energy usage based on actual thermal conditions
3Measurement precision
If temperature monitoring and control systems are added, then temperature regulation precision is improved, but device complexity increases
Solution Approach 1:
The temperature sensor is positioned in direct thermal contact with the joint components, providing localized temperature measurement at the critical interface where thermal regulation is most needed, ensuring accurate detection of temperature changes

AI summary
Devices that are implantable within a patient's body, and more specifically, to implantable joints (e.g. hip joint, knee joint, shoulder joint, etc.) having a heating system. For example, a device implantable within a patient's body may include a first member configured to be coupled to a first bone and a second member configured to be coupled to a second bone, the first and second members being operatively coupled to form a moveable joint. A heating system may be configured to controllably heat at least a portion of the at least one of the first and second members. The heating system may include a controller operable to cause a heating element to apply heat based on one or more external conditions (e.g. temperature, humidity, etc.).
