Belt Buckle With Deflectable Central Element for Anti-Tamper Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waist belt buckles with hook-and-pile-fasteners are difficult to open in deployment situations due to limited retention force and require time-consuming adjustments for size changes, and existing solutions either compromise security or are complex in design.
Innovation Solution
A one-piece belt buckle with a central flat element that deflects towards the waist belt, featuring inlet retainers that prevent unauthorized opening and allow adjustable length without modifying the belt, using an elastically deflectable spring element for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hook-and-pile-fasteners are used for belt closure, then the belt can be easily fastened, but the retention force is very limited and can be opened by attackers
Solution Approach 1:
The belt closure is divided into multiple independent pressure points (at least two) that must all be simultaneously pressed to open the belt. This segmentation of the opening action into multiple discrete points prevents unauthorized opening while maintaining ease of operation through the simple pressing motion.
Solution Approach 2:
The belt buckle mechanism is pre-configured with positively geared plastic parts that are already engaged in closed condition. The security feature is built into the structure beforehand, requiring simultaneous pressure at multiple predetermined points rather than allowing gradual or partial opening.
2Reliability
If conventional waist belt buckle mechanism with multiple pressure points is used, then security against unauthorized opening is improved, but adjustment of belt size becomes problematic and time-consuming
Solution Approach 1:
The belt inlet slot is designed to dynamically accommodate different belt lengths and configurations. The slot geometry allows the belt end to be inserted and secured without requiring removal of containers or complex disassembly, enabling quick adjustment while maintaining the multi-pressure-point security mechanism.
Solution Approach 2:
The belt buckle mechanism serves multiple functions simultaneously: it provides secure closure with anti-tamper security, allows quick adjustment for different belt sizes, and accommodates various belt configurations (including deployment belts with containers). This multi-functionality eliminates the need for separate adjustment procedures.
3Reliability
If metal hooks and additional retention elements are used to prevent opening, then security is improved, but the design becomes complex and requires multiple components
Solution Approach 1:
The retention elements are integrated directly into the belt buckle housing as a unified structure rather than being separate components. The positively geared plastic parts form an integrated mechanism that provides both the closure function and the security feature, eliminating the need for separate metal hooks and retention elements.
Solution Approach 2:
The belt buckle utilizes composite construction with plastic parts providing both structural support and security functionality. The positively geared plastic mechanism combines the retention function with the anti-tamper feature, replacing traditional metal components and reducing overall device complexity while maintaining security.

AI summary
A belt buckle is provided with a waist belt outlet slot (1) for connecting with a waist belt beginning (6) and at least one inlet retainer (5) engaging in openings of the belt at the opposite waist belt inlet slot (2).As a result of the design of the central section of the belt buckle as an essentially flat element (3), which permits deflection toward the waist belt, which reaches in the section of the, or of each inlet retainer (5) at least their height, can, in spite of a simple design, prevent an opening that is against the will of the carrier.
