Micrometer Heat Shield Anti-Slip Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional micrometers with heat shields lack anti-slip features, making them slippery when used with lubricants, which compromises usability during measurements.
Innovation Solution
Incorporating anti-slip protrusions on the heat shield and display cover of the micrometer, arranged regularly or irregularly, to provide traction and facilitate secure handling even with lubricants like oil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat shield cover is added to the micrometer, then thermal expansion of the frame is suppressed, but the heat shield cover becomes slippery when a user picks it up
Solution Approach 1:
The heat shield cover is designed with a porous structure that absorbs lubricants such as oil from the user's fingers. This absorption capability prevents the lubricants from creating a slippery surface, thereby maintaining good grip stability while preserving the thermal expansion suppression function of the heat shield cover
Solution Approach 2:
The heat shield cover incorporates an anti-slip part with a specific surface structure (porous or textured) in the region that contacts the user's fingers. This local modification provides lubricant absorption and improved grip only where needed, while the rest of the cover maintains its heat shielding properties
2Temperature
If the heat shield cover is made smooth, then it provides good thermal shielding, but it becomes difficult to grip when lubricants are present
Solution Approach 1:
The heat shield cover has different surface properties in different regions: a smooth surface for optimal heat shielding and an anti-slip part with porous or textured structure for improved grip. This local differentiation allows the cover to simultaneously provide effective heat shielding and secure handling even when lubricants are present
Solution Approach 2:
The anti-slip part of the heat shield cover uses porous material that absorbs lubricants. This porous structure is strategically placed to provide grip enhancement without compromising the overall heat shielding effectiveness of the cover
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 anti-slip features enhance the usability of the micrometer by preventing slippage, allowing users to maintain a secure grip and accurately measure object sizes, thereby improving measurement precision and comfort.
Implementation Method 1
the heat shield cover has a first anti-slip part... the first anti-slip part has a plurality of protrusions... the protrusions are formed like dots
Implementation Method 2
it is necessary to suppress the effect of thermal expansion of the frame due to the heat of the hand of a user holding the frame... the frame is covered with a heat shield cover

AI summary
A micrometer with good usability is provided. A micrometer has a frame with an anvil at one end and a spindle at another end, the spindle moving closer to or further away from the anvil. The frame is covered with a heat shield cover. The heat shield cover has a first anti-slip part. The first anti-slip part preferably has a plurality of protrusions.
