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

VSEngineering 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

Engineering Contradiction:
Improvealignment precisionVSAvoidadjustment convenience
Core Design Contradiction:
Manufacturing precisionVSEase of operation

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If the type band is not adjusted well, then the structure remains simple, but the stamped pattern is not clear

Engineering Contradiction:
Improvepattern clearnessVSAvoidadjusting mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

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

Inventive Principle:
Principle #25Self-service

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

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).
