Concave Pump for Wearable Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cylindrical pumps are difficult to integrate into devices with concave curved shapes, such as wearable terminals, due to size constraints, requiring either downsizing the pump or enlarging the device, which are both impractical solutions.
Innovation Solution
A pump with a concave shape in a planar view from the Y axis direction, featuring a sealed chamber, a movable wall, and an electromagnetically driven vibration actuator that allows fluid discharge, enabling the pump to be easily integrated into devices with curved surfaces without altering its size or the device's dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a cylindrical pump is provided in a device with a concave curved shape, then the pump can be integrated into the device, but the pump interferes with the device structure and cannot be properly provided
Solution Approach 1:
The pump housing is designed with a concave curved outer shape that matches the contour of the wearable device surface, allowing the pump to conform to the device's curved geometry without interference. This curvature adaptation enables seamless integration into the concave structure of wearable terminals.
Solution Approach 2:
The pump structure transitions from a traditional cylindrical three-dimensional form to a flattened concave shape that distributes volume across a two-dimensional surface, enabling it to fit within the contour constraints of wearable devices while maintaining functional volume.
2Volume of moving object
If the pump size is reduced to fit in the device, then the pump can be integrated, but it becomes difficult to reduce the size due to technical problems
Solution Approach 1:
The concave curved housing design allows the pump to utilize the available surface area of the wearable device, effectively distributing the pump's volume across a larger footprint while maintaining a low profile, thus avoiding the need for extreme miniaturization.
3Volume of moving object
If the device size is increased to accommodate the pump, then the pump can be provided, but the device becomes large
Solution Approach 1:
The pump is designed with a flattened profile that distributes its volume across the surface area of the device rather than protruding outward, allowing the pump to be accommodated within the device's contour without increasing the device's overall size.

AI summary
A pump contains a sealed chamber, a movable wall for changing a volume of the sealed chamber, and a vibration actuator which can be electromagnetically driven for displacing the movable wall to discharge fluid in the sealed chamber to an outside of the sealed chamber. Further, three axes perpendicular to each other are respectively defined as an X axis, a Y axis, and a Z axis. When a direction along the X axis is defined as an X axis direction, a direction along the Y axis is defined as a Y axis direction, and a direction along the Z axis direction is defined as a Z axis direction, an outer shape of the pump is a concave shape in a planar view from the Y axis direction.
