Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ear mounts improve the wearing sensation of the insertion part inserted into the ear canal but fail to enhance the wearing sensation of the body part fitted into the conchal cavity.
Innovation Solution
An ear mount design featuring a body part with a protrusion, a cylindrical part, an inner housing, and a cover that forms an air chamber, along with a pressure regulator to control ventilation based on pressure differences, enhancing the contact feel of the body part fitted into the conchal cavity by managing air pressure and discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the body part is fitted tightly into the conchal cavity to improve wearing sensation, then the contact feel improves, but the load on the head increases
Solution Approach 1:
The patent applies pneumatic principles by introducing an air chamber between the cover and inner housing that can be pressurized or evacuated. This pneumatic system provides adaptive pressure distribution across the conchal cavity, improving contact and wearing sensation while the pressure regulator controls the force to prevent excessive head load. The air pressure acts as a mediator to distribute forces evenly.
Solution Approach 2:
The patent changes the physical state of the air in the air chamber by controlling pressure and volume through the pressure regulator. By adjusting the air pressure parameter, the system can dynamically adapt the contact force between the body part and conchal cavity, optimizing wearing sensation while controlling the load on the head. The elastic member's expansion state is also changed through pressure control.
2Force
If air is vented freely from the air chamber to reduce head load, then the load decreases, but the wearing sensation deteriorates
Solution Approach 1:
The pressure regulator functions as a feedback control device that monitors the pressure in the air chamber and automatically adjusts the ventilation of air. When pressure exceeds a set threshold, the regulator vents air to reduce pressure and head load. When pressure drops, it prevents further venting to maintain adequate contact force. This closed-loop feedback ensures both comfortable load levels and good wearing sensation.
Applied Scientific Principles
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 design reduces the load on the head during mounting and maintains a soft contact feel by regulating air pressure, improving the overall wearing sensation of the ear mount.
Implementation Method 1
a pressure regulator configured to control ventilation of air between the air chamber and an outer space through the opening in accordance with a pressure difference between the air chamber and the outer space
Implementation Method 2
The elastic member is expanded by causing air to flow into the inside of the elastic member and thus the elastic member is in close contact with the inner wall of the ear canal

AI summary
An ear mount includes a body part mounted on a conchal cavity and an insertion part mounted on a cylindrical part and inserted into an ear canal. A cover configured to cover an inner housing of the body part with a protrusion formed thereon includes: a first end sealed and fixed to the inner housing; an intermediate part separated from the inner housing to form an air chamber between the intermediate part and the inner housing, and configured to cover the protrusion; a second end located opposite to the first end with the intermediate part therebetween; and an opening located at the second end and through which the cylindrical part is inserted. The ear mount includes a pressure regulator for controlling ventilation of air between the air chamber and an outer space through the opening in accordance with a pressure difference between the air chamber and the outer space.
