Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat assemblies fail to effectively reduce pain and discomfort associated with dysmenorrhea and sciatica, as they lack the ability to sense and respond to these conditions.
Innovation Solution
A seat assembly equipped with a temperature control unit and an electronic control unit (ECU) that senses user discomfort through sensors and adjusts seat positions and temperature to alleviate pain, using actuators, a bladder assembly, and pulsed electromagnetic field (PEMF) coils to provide targeted relief.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seat assembly is configured with sensors and control units to detect and respond to dysmenorrhea and sciatica conditions, then the ability to reduce pain and discomfort is improved, but the device complexity increases
Solution Approach 1:
The seat assembly integrates multiple functions into a single system: sensors detect user conditions, the ECU processes information, temperature control units provide thermal therapy, PEMF coils deliver electromagnetic field therapy, and actuators adjust seat position. This multi-functional integration resolves the contradiction by achieving reliable pain relief through coordinated actions of various subsystems while managing complexity through unified control architecture.
Solution Approach 2:
The system employs sensors that continuously monitor user conditions and provide feedback to the ECU. Based on this feedback, the ECU automatically adjusts temperature control, PEMF therapy delivery, and seat positioning to optimize pain relief. This closed-loop feedback mechanism ensures reliable pain reduction while automating the complex coordination of multiple therapeutic functions.
2Extent of automation
If the seat assembly uses multiple control units and actuators to provide automated therapy, then the extent of automation is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple control functions (temperature control, PEMF therapy control, seat position control) into a single ECU that receives sensor input and coordinates all therapeutic actions. This merging of control functions achieves high automation while reducing the complexity that would result from multiple independent control systems operating separately.
Solution Approach 2:
The seat assembly automatically detects user conditions through sensors and initiates appropriate therapeutic actions without requiring user intervention. The system self-regulates temperature, PEMF coil activation, and seat positioning based on sensor feedback, achieving extensive automation while simplifying the user experience despite the underlying system complexity.

AI summary
A seat assembly may include a seat having a seat base and a seat back, a temperature control unit disposed at least partially in the seat back, and/or an ECU connected with the temperature control unit. The ECU may be configured to receive an input related to (i) a first state corresponding to symptoms and/or discomfort associated with dysmenorrhea and/or (ii) a second state corresponding to symptoms and/or discomfort associated with sciatica. The ECU may be configured to operate the seat assembly according, at least in part, to the input.
