Profile Gauge Locking Assembly for Precise Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional profile gauges fail to precisely fix the profile curve line of an object after aligning slidable measuring members, leading to instability in measurements.
Innovation Solution
A profile gauge design featuring a body with parallel ruling portions, a holding plate with extensions and locking assembly, and slidable measuring members with elongated apertures and contacting tabs, allowing for precise alignment and locking of the measuring members using a magnetic attachment and a rotatable locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If slidable measuring members are moved to align with the profile curve line, then measurement adaptability is improved, but measurement precision deteriorates because they cannot be fixed precisely
Solution Approach 1:
The locking assembly is activated after the measuring members are aligned with the profile curve line, preliminarily securing them in the aligned position to prevent any subsequent movement or deviation, thereby maintaining measurement precision while preserving measurement adaptability
Solution Approach 2:
The locking assembly acts as an intermediary mechanism between the slidable measuring members and the holding plate, providing a secure connection that fixes the measuring members in their aligned positions without interfering with their ability to be repositioned for different measurement scenarios
2Measurement precision
If a locking mechanism is added to fix measuring members, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The locking assembly is integrated with the holding plate structure, merging the locking function into the existing device framework rather than adding a completely separate mechanism, thereby achieving precise fixation while minimizing the increase in device complexity
Solution Approach 2:
The locking assembly is designed to be operated manually by the user, utilizing human action rather than requiring complex automated locking mechanisms, thus achieving reliable fixation with minimal structural complexity

AI summary
A profile gauge contains: a body, a holding plate, a plurality of slidable measuring members, and a locking assembly. The body is formed in an elongated plate shape and includes an accommodating chamber defined thereon and two ruling portions parallelly arranged on two sides of the accommodating chamber, wherein each ruling portion has a graduation for measuring a distance between two points of a profile curve line of an object. The holding plate is rectangular and includes an insertion extending outwardly from a first end thereof and an extension extending outwardly from a second end thereof. Each slidable measuring member includes a fixed thickness and an elongated aperture defined thereon, wherein a width of the elongated aperture is more than a width between the two sides of the holding plate. The locking assembly is fixed on the extension to limit a slidable movement of each slidable measuring member.
