Awakening inducing device and awakening inducing system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional awakening devices are not effective in fully awakening users, as they do not adequately stimulate the nerve activity in the supplementary motor area, which is crucial for eliminating drowsiness.
Innovation Solution
An awakening inducing device is designed with a vibration device placed in a seat to oppose the muscle belly portion or insertion portion of the hamstring, and a control device that provides vibration stimulation to these areas, along with a state detecting sensor and determining device to assess the user's drowsiness and adjust the stimulation accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vibration stimulation is given to conventional locations (tendon portions), then the device can provide awakening effect, but the awakening effect is not sufficient to fully awaken users
Solution Approach 1:
The patent applies local quality by identifying specific muscle belly portions (biceps femoris, semitendinosus, semimembranosus) as optimal stimulation locations. Instead of using generic tendon portions, the invention targets specific local areas of the hamstring muscles where vibration stimulation most effectively activates the supplementary motor area, thereby improving awakening effectiveness while maintaining manageable device complexity through precise but not overly complex positioning.
2Reliability
If vibration stimulation is given to muscle belly portion or insertion portion of hamstring, then nerve activity in supplementary motor area is increased and user is awakened more fully, but the device requires precise positioning opposite the muscle
Solution Approach 1:
The patent employs preliminary action by pre-positioning the vibration device within the seat at locations that correspond to the muscle belly portions or insertion portions of the hamstring muscles. The vibration device is arranged in advance to oppose these specific muscle areas, so that when activated, it immediately provides effective stimulation without requiring complex real-time positioning adjustments, thus reducing manufacturing precision requirements while maintaining high awakening effectiveness.
3Productivity
If vibration stimulation is applied to the hamstring muscles, then the supplementary motor area is activated and drowsiness is eliminated, but the device structure becomes more complex with additional positioning requirements
Solution Approach 1:
The patent applies merging by integrating the vibration device directly into the seat structure. The vibration device is combined with the seat cushion or base, eliminating the need for separate positioning mechanisms and reducing overall device complexity. This integration allows the vibration stimulation to be delivered effectively to the hamstring muscles while maintaining a simple, unified seat design that does not require additional complex components.

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 effectively awakens users more fully than conventional methods by stimulating the supplementary motor area, thereby increasing nerve activity and leading to enhanced alertness.
Implementation Method 1
a vibration device disposed in a seat at a position where the vibration device opposes at least one of a muscle belly portion or an insertion portion of a hamstring of a user sitting on the seat; and a control device that, by controlling the vibration device, causes the vibration device to give vibration stimulation to the at least one of the muscle belly portion or the insertion portion
