Push-Type Helmet Buckle With Toothed Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmet buckle designs, particularly those requiring a pull mechanism, can be difficult to operate while engaging in sports like motorcycle riding or skiing due to the need for manual leverage.
Innovation Solution
A push-type helmet buckle design featuring a locking unit pivotally rotated by an operating unit, utilizing a second toothed portion and an elastic member to facilitate easy engagement and disengagement of the band unit, allowing for effortless operation with minimal manual effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pull-type lever mechanism is used for fastening and unfastening the helmet band, then the locking mechanism can be securely engaged, but the operation becomes difficult to perform while riding a motorcycle or engaging in sports activities
Solution Approach 1:
The patent inverts the conventional pull-type lever mechanism into a push-type button mechanism. Instead of requiring the user to pull a lever to disengage the locking mechanism, a button is pushed to trigger the release. This inversion fundamentally changes the operation from a complex pulling motion to a simple pushing action, making it much easier to operate during sports activities while maintaining reliable locking through the toothed engagement mechanism
2Adaptability or versatility
If a complex lever rotation mechanism with multiple components is used to achieve length adjustment, then the band can be securely fastened at multiple positions, but the device complexity increases making it harder to operate
Solution Approach 1:
The patent merges the fastening and length adjustment functions into a single integrated mechanism. The button simultaneously controls both the locking engagement and the band length adjustment by triggering the lever rotation that disengages the teeth from the gear. This consolidation reduces the number of separate controls and components the user must manipulate, simplifying operation while preserving both secure fastening and adjustable length capabilities
Solution Approach 2:
The lever mechanism serves multiple functions: it controls both the locking engagement and the band length adjustment. By making the lever universal for both operations, the patent reduces the need for separate mechanisms, thereby decreasing overall device complexity while maintaining adaptability for different band lengths and secure fastening
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
Enables easy and efficient fastening and unfastening of the helmet band, enhancing user convenience and safety during sports activities by simplifying the operation of the buckle.
Implementation Method 1
an elastic member provided between the base unit and the locking unit for providing elastic force so as to allow the second toothed portion to be pushed toward the band unit
Implementation Method 2
The locking unit is provided on one end thereof, which faces the operating unit, with a first slope, and on one end thereof, which faces the locking unit, with a second slope, and wherein, when the user pushes the operating unit as to linearly move toward the locking unit, the second slope may slide on the first slope to thereby push one surface of the locking unit, causing the locking unit to be pivotally rotated

AI summary
Disclosed is a buckle (100) for a helmet, including a band unit (300) provided with a first toothed portion (340), a base unit (400) for guiding sliding of the band unit when the band unit is introduced or retracted, a locking unit (500) pivotally rotatably fastened to one side of the base unit, the locking unit being provided on one surface thereof, which faces the band unit, with a second toothed portion (540) so as to correspond to the first toothed portion, the second toothed portion being pushed toward the band unit, and an operating unit (600) fastened to an opposite side of the base unit so as to be movable toward the locking unit, the operating unit serving to pivotally rotate the locking unit so that the second toothed portion is moved away from the band unit when it is moved toward the locking unit so as to apply a pressure to the locking unit.
