Ultrasonic Tool Spigot for Consistent Hold-Down Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasound devices for surface treatment and welded joints suffer from inconsistent quality due to orientation-dependent gravitational effects on hold-down force, inadequate cooling, and ergonomic limitations, leading to reduced operational efficiency and increased operator fatigue.
Innovation Solution
The ultrasound device features a sleeve with a forced air-cooling system, a moving spigot with adjustable pins for consistent hold-down force, and an ergonomically positioned handle, allowing for free rotation of the working head and enhanced anchoring capabilities to maintain consistent treatment quality across various spatial positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the device uses a spring-based hold-down mechanism with gravitational force, then the structure is simple, but the treatment quality becomes inconsistent due to orientation-dependent force variation
Solution Approach 1:
The patent introduces a counterweight mechanism that compensates for the gravitational force variations. A movable spigot with pins engages with shaped slots in the housing, creating a mechanical counterbalance system. This counterweight mechanism offsets the orientation-dependent gravitational effects on the spring-loaded strikers, maintaining consistent hold-down force regardless of device orientation, thereby resolving the contradiction between structural simplicity and treatment quality consistency.
2Stability of the object's composition
If the working head is fixed in position, then the structure is stable, but the device cannot treat hard-to-reach zones effectively
Solution Approach 1:
The patent implements a dynamic working head attachment system that allows rotation and quick removal. The working head can be rotated to different angular positions and quickly detached/reattached, enabling the device to access hard-to-reach zones while maintaining structural stability when in use. This dynamic attachment mechanism resolves the contradiction between structural stability and adaptability to difficult geometries.
3Volume of moving object
If the handle is placed directly on the housing, then the device is compact, but operator fatigue increases due to difficulty in maintaining tool position under vibro-impact conditions
Solution Approach 1:
The patent repositions the handle in another dimension by extending it away from the housing along the longitudinal axis. This dimensional separation provides the operator with better leverage and control over the vibrating tool, reducing fatigue while maintaining device compactness. The extended handle position allows the operator to maintain proper tool positioning more easily under vibro-impact conditions.
4Device complexity
If the transducer cools only by atmospheric air convection, then the cooling system is simple, but the operational time is reduced due to overheating
Solution Approach 1:
The patent implements a forced air cooling system using pneumatic principles. Compressed air is directed through channels to cool the ultrasonic transducer actively, significantly improving heat dissipation efficiency. This pneumatic cooling approach extends operational time by preventing overheating while adding minimal complexity to the device structure.

AI summary
An ultrasound device for the treatment of surfaces and welded joints is disclosed. The device has a housing with a plurality of shaped slots formed therein. A reciprocally moveable sleeve is attached to the housing, and contains an ultrasonic transducer. A reciprocally moveable attachment is attached to an operating end of the sleeve, and has a detachable working head mounted thereon. A pin is positioned in a pin slot on the housing, and anchors the sleeve to the housing to limit movement of the sleeve. The pin is biased towards the front of the pin slot by means of a spring, and a moveable spigot provides a predetermined contact force between the ultrasound device and a work surface. The spigot has spigot pins that are inserted into the plurality of shaped slots in the housing in order to restrict axial movement of the spigot, thereby providing added compression or tension to the spring in order to provide the predetermined contact force.
