Rotating Stamp Seat Adjusting Type Band Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotating seats for stamps face challenges in convenient adjustment of the type band, leading to potential slanting and uneven ink distribution, resulting in unclear stamped patterns.
Innovation Solution
The rotating seat incorporates a first supporting frame, a second supporting frame, a printing assembly, an adjusting member, and auxiliary members, including a threaded shank and springs, which allow for precise adjustment of the type band's height and alignment with the pad, ensuring even ink distribution and clear patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the type band is adjusted by two screws to make it flush with the pad, then the alignment can be improved, but it is hard to judge whether the adjusting degrees are same or not, leading to potential slanting
Solution Approach 1:
The patent merges the adjustment function of two separate screws into a single adjusting member with a threaded shaft. This single member simultaneously adjusts both sides of the second supporting frame, ensuring equal adjustment degrees and eliminating the difficulty of judging whether adjustments are symmetrical, thereby preventing slanting while maintaining alignment precision
Solution Approach 2:
The threaded shaft acts as an intermediary mechanism that translates rotational motion into linear displacement for both sides of the supporting frame. By using this intermediary, the adjustment is automatically coordinated and synchronized, making the operation convenient while achieving precise alignment without the need for separate screw adjustments
2Manufacturing precision
If the type band is not adjusted well, then the structure remains simple, but the stamped pattern is not clear
Solution Approach 1:
The adjusting member with the threaded shaft enables the operator to easily achieve proper alignment through simple rotational adjustment. The self-service nature of this mechanism allows users to obtain clear stamped patterns without requiring complex adjustment procedures or specialized skills, thereby improving pattern clearness without significantly increasing device complexity
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
This design enhances the convenience of adjusting the type band, ensures even ink distribution, and improves the clarity and quality of stamped patterns by maintaining alignment and stability during the stamping process.
Implementation Method 1
The adjusting member has a bottom plate, a threaded shank, and a working slot. The threaded shank is formed on the top surface of the bottom plate, is inserted into and engaging with the threaded hole of the second supporting frame
Implementation Method 2
The two auxiliary members are respectively inserted into the two recesses of the first supporting frame. Each auxiliary member has two ends respectively abutting a corresponding one of the first retaining surfaces and a corresponding one of the second retaining surfaces

AI summary
A rotating seat has a first supporting frame (10) having an assembling member (13), a second supporting frame (20) having a threaded hole (22), a printing assembly (30), an adjusting member (40), and two auxiliary members (50). The second supporting frame (20) is moveably mounted on the first supporting frame (10). The printing assembly (30) is mounted on the second supporting frame (20). The adjusting member (40) is disposed on the assembling member (13) and engages with the threaded hole (22). Each auxiliary member (50) has two ends respectively abutting the first supporting frame (10) and the second supporting frame (20). The height of the printing assembly (30) relative to the first supporting frame (10) is adjusted by the adjusting member (40) to make a type band (31) of the printing assembly (30) flush with a pad (60).
