Holding Mechanism With Biasing Tab For Measuring Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional holding tools for measuring devices with detection devices are complex, difficult to attach and detach, and require screw holes, limiting positioning freedom and increasing costs.
Innovation Solution
A holding mechanism with a pair of holding members featuring a first groove on the scale frame, a second groove on the detection device, and a projecting tab that biases the scale and detection device apart, allowing easy attachment and detachment without screws, using friction for displacement regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If holding members are screwed into place using conventional holding tools, then fixation reliability is improved, but device complexity and ease of operation deteriorate due to complicated attachment/detachment tasks and requirement for screw holes
Solution Approach 1:
The holding member is segmented into distinct functional elements: a holding portion with hook-shaped engagement features that latch onto grooves, and a projecting tab that inserts into a gap to provide biasing force. This segmentation allows each element to perform its specific function independently, simplifying the overall structure while maintaining reliable fixation without requiring screws or complex assembly procedures
Solution Approach 2:
Instead of using threaded screws that require rotation and precise engagement, the invention inverts the fixation mechanism by using a hook-shaped portion that simply latches onto grooves and a tab that pushes into a gap. This inverted approach replaces complex rotational threading with simple latching and biasing actions, dramatically simplifying both the holding tool structure and the attachment/detachment operations
2Reliability
If screw holes are formed in the scale frame for fixing holding members, then fixation reliability is improved, but manufacturing cost and ease of manufacture deteriorate due to additional tapping work
Solution Approach 1:
The invention extracts the fastening function from the scale frame structure itself. Instead of requiring screw holes to be formed in the scale frame, the holding member's hook-shaped portion engages with grooves that are part of the holding member's own structure, and the projecting tab engages with a gap between the detection device and scale frame. This extraction eliminates the need for additional tapping work on the scale frame, simplifying manufacturing while maintaining reliable fixation
Solution Approach 2:
The holding member acts as an intermediary element that provides its own engagement features (grooves and projecting tab) rather than requiring modifications to the scale frame. The grooves in the holding member and the gap between components serve as intermediaries that enable fixation without direct screw holes in the scale frame, reducing manufacturing complexity while ensuring reliable attachment
3Manufacturing precision
If holding position is limited by screw hole location, then manufacturing precision is improved, but adaptability and ease of operation deteriorate due to reduced positioning freedom
Solution Approach 1:
The holding member incorporates a movable regulating member that can slide along the holding portion to adjust the position where the projecting tab engages with the gap. This dynamic adjustment capability allows the detection device to be positioned at multiple locations along the scale frame without requiring multiple pre-drilled screw holes, providing both positioning precision and adaptability for different measurement configurations
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 mechanism simplifies attachment and detachment, prevents damage during transport, reduces costs by eliminating the need for screw holes, and enhances positioning flexibility.
Implementation Method 1
The pair of holding members are displaced from the first and second sides toward the detection device along the length direction of the scale frame and the projecting tab is inserted into a gap between the scale frame and the detection device, and thereby the projecting tab biases the scale frame and the detection device in mutually separating directions

AI summary
A holding mechanism used in a measuring device includes a first groove, a second groove, and a pair of holding members holding the detection device by being attached to first and second sides in a length direction of a scale frame. The pair of holding member include a plate-like main body, a first hook portion engaging with the first groove, a second hook portion engaging with the second groove, and a projecting tab projecting from the main body and positioned at a gap. The pair of holding members are displaced from first and second sides toward the detection device along the length direction of the scale frame and the projecting tab is inserted into the gap, and thereby the projecting tab biases the scale frame and the detection device in mutually separating directions.
