Watch Strap Buckle Hidden Locking Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The pin buckle type watch strap buckle is easily fastened and unfastened, which can lead to unintended removal of wearable intelligent equipment, disrupting real-time monitoring functions, and existing solutions with additional locking devices are complex and may cause privacy leakage.
Innovation Solution
A watch strap buckle with a hidden locking device that includes a U-shaped snap ring, a rotating shaft, a buckle tongue, and a locking box with a connecting rod and spring bolt that can extend and retract, allowing for secure locking and manual release of the buckle tongue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional locking device is mounted outside the watch strap buckle, then the watch strap can be prevented from being loosened, but the structure becomes complex and user privacy may be compromised
Solution Approach 1:
The locking device is nested within the buckle tongue structure itself. The locking protrusion is formed as an integral part of the buckle tongue, and the locking groove is formed on the snap ring. This nested integration eliminates the need for separate external locking devices, maintaining security functionality while simplifying the overall structure and avoiding privacy concerns associated with external mounting.
Solution Approach 2:
The locking function is merged with the existing buckle tongue and snap ring components. The locking protrusion on the buckle tongue and the locking groove on the snap ring work together as an integrated locking mechanism, combining the fastening and locking functions into a unified structure rather than adding separate components.
2Reliability
If a separate locking device is added to the watch strap buckle, then the watch strap can be securely locked, but the operation becomes inconvenient requiring separate locking steps
Solution Approach 1:
The locking protrusion is pre-formed as an integral part of the buckle tongue structure. When the buckle tongue is inserted into the snap ring during the normal fastening operation, the locking protrusion automatically engages with the locking groove on the snap ring. This preliminary integration of the locking feature into the buckle tongue allows locking to occur automatically as part of the fastening action, eliminating the need for separate locking steps.
3Reliability
If the locking device is mounted outside the watch strap, then it can prevent unauthorized removal, but it causes unnecessary discrimination and privacy leakage
Solution Approach 1:
The locking mechanism is nested within the buckle tongue and snap ring structure, which are components already integrated into the watch strap system. The locking protrusion and locking groove are formed as part of the internal buckle mechanism, making the locking function invisible and integrated rather than externally visible, thereby avoiding discrimination and privacy concerns.
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 hidden locking device securely prevents unauthorized loosening of the watch strap, maintaining the integrity of real-time monitoring functions while being compact and user-friendly, without compromising user privacy.
Implementation Method 1
a spring bolt linked to the connecting rod are mounted in the box body
Implementation Method 2
a connecting rod capable of extending and retracting left and right, and a spring bolt linked to the connecting rod

AI summary
The present disclosure discloses a watch strap buckle with a hidden locking device. The watch strap buckle includes a U-shaped snap ring; a rotating shaft is arranged at an open end of the U-shaped snap ring; one end of a buckle tongue is mounted on the rotating shaft, and the other end of the buckle tongue can be inserted into a watch strap hole; first limiting holes for the spring bolt to extend and retract are formed in left and right side surfaces of the box body; second limiting holes for the spring bolts to extend and retract are correspondingly formed in corresponding positions of left and right supports of the snap ring; and the watch strap buckle further includes an independent retraction actuation rod. The watch strap buckle is stable, reliable, convenient and practical.
