Self-Inking Stamp With Elastic Force Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional self-inking stamps face issues with non-uniform ink application due to uneven adjustment of fasteners, leading to inclined type bands and indistinct stamping patterns.
Innovation Solution
The stamp design incorporates a die bracket, first and second elastic elements, and a bearing bracket with guiding elements, ensuring the type band remains level by using adjustable elastic elements to distribute force uniformly, preventing obliqueness and ensuring alignment with the rubber die.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two fasteners are used to adjust the bearing bracket relative to the die bracket, then the type band can be positioned, but non-uniform adjustment causes the type band to incline and ink to attach non-uniformly
Solution Approach 1:
The patent introduces elastic elements as intermediary components between the fasteners and the bearing bracket. These elastic elements act as mediators that distribute the adjustment force uniformly across the bearing bracket, ensuring that when fasteners are tightened, the bearing bracket and type band are positioned evenly relative to the die bracket, eliminating inclination and achieving uniform alignment.
2Measurement precision
If fasteners are adjusted to position the type band, then the stamping pattern can be aligned, but non-uniform fastener adjustment leads to indistinct stamping patterns
Solution Approach 1:
The elastic elements serve as intermediary components that transmit and distribute the clamping force from the fasteners uniformly to the bearing bracket. This ensures that the type band is positioned evenly relative to the die bracket, resulting in clear, distinct stamping patterns by preventing non-uniform contact and ink transfer.
Solution Approach 2:
The patent utilizes the elastic properties of the elastic elements to change the mechanical parameters of the system. The elasticity allows for uniform distribution of force and automatic compensation for minor misalignments, ensuring consistent contact between the type band and die bracket, which produces reliable and distinct stamping patterns.
