Solution Overview
Problem
Existing heating and cooling stimulation devices do not effectively reduce fatigue in subjects by dynamically adjusting the intensity and duration of hot and cold stimulation based on the subject's fatigue level.
Innovation Solution
A heating and cooling stimulation device that includes a stimulation supply unit for alternating hot and cold stimulation, an estimation unit to assess the subject's fatigue level, and a control unit that increases the intensity and duration of cold stimulation as fatigue levels rise, enhancing blood flow by widening and narrowing blood vessels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed intensity hot and cold stimulation is supplied alternately, then the device structure is simple, but the fatigue reduction effect is insufficient
Solution Approach 1:
The patent implements dynamic adjustment of stimulation intensity and duration based on real-time fatigue level detection. The control unit modifies the intensity and duration of hot and cold stimulation alternately according to the detected fatigue level, transforming the fixed stimulation system into a dynamic adaptive system that optimizes fatigue reduction effectiveness.
Solution Approach 2:
The patent incorporates a fatigue level detection unit that continuously monitors the subject's fatigue state and feeds this information back to the control unit. This feedback mechanism enables the system to automatically adjust stimulation parameters based on actual physiological responses, creating a closed-loop control system that enhances fatigue reduction while maintaining reasonable system complexity.
2Reliability
If the intensity and duration of cold stimulation are increased to enhance fatigue reduction, then the fatigue reduction effect is improved, but the energy consumption increases
Solution Approach 1:
The patent dynamically adjusts the intensity and duration of cold stimulation based on real-time fatigue level detection rather than maintaining constant high intensity. The control unit optimizes the alternation between hot and cold stimulation phases, increasing cold stimulation only when fatigue levels warrant it, thereby reducing unnecessary energy consumption while maintaining effective fatigue reduction.
3Reliability
If the stimulation intensity is increased to improve fatigue reduction, then the fatigue reduction effect is enhanced, but the comfort of the subject may deteriorate
Solution Approach 1:
The patent employs periodic alternation between hot and cold stimulation phases rather than continuous high-intensity stimulation. This periodic action allows tissue to adapt and recover between phases, distributing the thermal stress over time and reducing peak discomfort while maintaining cumulative fatigue reduction effectiveness through repeated cycles of vasodilation and vasoconstriction.

AI summary
A heating and cooling stimulation device includes a stimulation supply unit configured to supply hot stimulation and cold stimulation to a subject; an estimation unit configured to estimate a fatigue level of the subject; and a control unit configured to control an operation of the stimulation supply unit so as to supply the hot stimulation and the cold stimulation alternately to the subject in accordance with the fatigue level estimated by the estimation unit. The control unit controls the operation of the stimulation supply unit such that an amount of the cold stimulation received by the subject increases as the fatigue level estimated by the estimation unit becomes higher.
