Oscillation Device Lid Body Alignment Marks for Sealing Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing techniques for oscillation devices are prone to misalignment, leading to potential air leaks due to the positional variability between the lid body and the container, which can result in insufficient sealing.
Innovation Solution
A lid body design featuring a groove portion and strategically placed marks on the second surface, allowing for precise positioning and alignment to prevent misalignment during the sealing process, thereby enhancing detection accuracy and reducing the likelihood of sealing failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If seam welding is performed to join the lid body and container, then the sealing is improved, but the positional relationship between the lid body and container may vary causing misalignment
Solution Approach 1:
The mark is provided on the second surface of the lid body at a position that does not overlap with the outer peripheral edge, enabling preliminary position recognition before the sealing process. This allows the heating beam to be accurately positioned based on the mark, preventing misalignment that would otherwise occur during seam welding due to variations in the lid body's position relative to the container.
2Reliability
If the unsealed area is irradiated with a heating beam for sealing, then the sealing is improved, but misalignment between the unsealed area and heating beam may occur
Solution Approach 1:
The mark serves as an intermediary element between the unsealed area (groove portion) and the heating beam. By providing the mark on the second surface at a position that does not overlap with the outer peripheral edge, the mark enables accurate position detection of the groove portion, ensuring that the heating beam is correctly positioned to seal the unsealed area without misalignment.
3Stability of the object's composition
If the mark is provided on the second surface at a position not overlapping with the outer peripheral edge, then the mark is not deformed by joining, but the detection of the groove portion position must be calculated
Solution Approach 1:
The mark is provided on the second surface of the lid body, which is a different dimension (opposite surface) from where the groove portion is located. This spatial separation ensures that the mark is not deformed by joining operations at the outer peripheral edge. The position of the groove portion is then calculated based on the mark's known position and the lid body's dimensions, transforming a direct measurement problem into a calculation problem that maintains mark stability.
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 proposed design ensures accurate positioning of the groove portion, reducing the risk of air leaks and enhancing the sealing reliability by providing clear recognition areas and positions for the marks, even under deformation or melting conditions.
Implementation Method 1
the unwelded part (the above unsealed area) is irradiated with a heating beam, thus sealing the lid body and the opening peripheral edge together

AI summary
A lid body includes: a first surface; a second surface having a top-bottom relation with the first surface; an outer peripheral surface connecting the first surface and the second surface; a groove provided in the first surface from the outer peripheral surface toward an interior of the first surface; and first and second marks arranged at positions that do not overlap with an outer peripheral edge of the second surface in a plan view.
