Tape Measure Belt Holder Locking Jaw for Secure Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tape measures easily separate from typical belt holders when a worker moves vigorously, necessitating a secure locking mechanism that allows detachment only when necessary.
Innovation Solution
A belt holder with a locking bracket featuring a locking jaw, rotation shaft, rotational force input portion, and a push button mechanism that switches between locked and unlocked states through a one-way rotation inducing groove and position maintenance pin, ensuring the tape measure remains secured unless intentionally released.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a typical belt holder with a clip through hole is used to attach the tape measure, then the tape measure can be easily attached and detached, but the tape measure easily separates from the belt holder when a worker moves vigorously
Solution Approach 1:
The locking bracket is designed to rotate between locked and unlocked positions, transitioning from a static holding structure to a dynamic locking mechanism. The bracket can rotate to engage the locking jaw with the belt clip, providing secure attachment during vigorous movement while maintaining ease of attachment and detachment when needed.
Solution Approach 2:
The system changes the state parameter of the belt clip from unsecured to locked by rotating the locking bracket. This parameter change is controlled by the push button mechanism, which rotates the locking bracket to engage the locking jaw, thereby changing the security state without requiring complex manual manipulation.
2Reliability
If a locking mechanism is added to prevent separation during vigorous movement, then the security of attachment is improved, but the device complexity increases
Solution Approach 1:
Multiple functions are merged into a single push button mechanism: it acts as both the actuator for rotating the locking bracket and the indicator for the locked/unlocked state. The position maintenance pin combines positioning and state indication functions, reducing the need for separate components and simplifying the overall structure despite the added locking capability.
Solution Approach 2:
The locking mechanism is designed to be self-latching through the rotational engagement of the locking bracket and locking jaw. Once rotated into the locked position, the mechanism maintains itself without requiring continuous external force or complex control systems, reducing the need for additional actuators or control components.
3Ease of operation
If a push button mechanism with one-way rotation inducing groove is used to switch the locking jaw, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The position maintenance pin acts as an intermediary element that translates the simple up/down motion of the push button into the rotational motion required to engage or disengage the locking jaw. This intermediary mechanism provides a clear mechanical linkage that is easy to operate while maintaining a relatively simple structure through the use of a guided groove rather than complex gear systems.
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 securely attaches the tape measure to the belt holder, preventing accidental detachment during vigorous movements while allowing easy release when needed, enhancing usability and convenience.
Implementation Method 1
a bracket spring provided in the holder body to elastically support the locking bracket in one direction so that the locking jaw of the locking bracket is located at a position that does not prevent the belt clip from coming off
Implementation Method 2
a push button spring provided in the holder body to elastically support the push button in an upward direction

AI summary
Proposed is a belt holder for a tape measure including a holder body, a clip holding part, a locking bracket, a bracket spring, a push button with a one-way rotation inducing groove, a push button spring, and a position maintenance pin, wherein due to an operation of the push button and the elastic force of the push button spring, a locking jaw of the locking bracket can be easily switched between locked and unlocked states as the push button is pushed in and out.
