Elastic Sheet Positioning Device for Ink Pad Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional positioning devices for ink pad containers fail to provide stable positioning, leading to movable allowances and uneven ink distribution, making it difficult to achieve both ease of assembly and stability.
Innovation Solution
A positioning device with elastic sheets and through grooves that allow positioning protrusions to abut against longitudinal ribs of the ink pad container, ensuring firm positioning and even ink distribution by utilizing the resilience of the elastic sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protruding height of positioning protrusions is increased for firm abutment, then positioning stability is improved, but assembly ease deteriorates as the ink pad container becomes hard to insert or press out
Solution Approach 1:
The positioning protrusions are designed with elastic properties, transforming them from static rigid structures to dynamic flexible elements. During assembly, the elastic positioning protrusions can deform to accommodate the ink pad container, and after assembly, they rebound to provide firm positioning, thus resolving the contradiction between easy assembly and stable positioning
Solution Approach 2:
The invention changes the physical parameter of the positioning protrusion from rigid to elastic, allowing it to change shape under external force during assembly, then maintain a stable elastic force for positioning after assembly, thereby achieving both easy assembly and reliable positioning
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 positioning device securely fixes the ink pad container, ensuring even ink distribution and clear stamped patterns, while allowing for easier assembly and accommodating size variations through increased tolerance allowances.
Implementation Method 1
each one of the two elastic sheets has an arm and a positioning protrusion... The positioning protrusion is pressed by a resilience of the corresponding one of the two elastic sheets to abut the two longitudinal ribs

AI summary
A positioning device for an ink pad container has a body and two elastic sheets. The two elastic sheets are respectively formed on two lateral side surfaces of the body. Each one of the two elastic sheets has an arm and a positioning protrusion. The arm is formed on a corresponding one of the two lateral side surfaces of the body, and is inserted into a corresponding one of two through grooves of the body. The positioning protrusion is formed on an inner side surface of the arm and is inserted into the body. An ink pad container may be firmly positioned into the body by the two elastic sheets. The tolerance allowances of the positioning device and the ink pad container are increased by the resiliences of the two elastic sheets. The positioning device can simultaneously satisfy the requirements for ease in assembly and for the positioning stability.
