Custom Security Fasteners With Asymmetric Drive Cavities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screws and bolts can be easily removed and stolen due to their widespread compatibility with standard screwdrivers, posing a security risk for items such as electrical panels and other equipment.
Innovation Solution
The use of custom connectors with unconventional heads and matching custom converters that are not compatible with standard tools, ensuring that only those with the correct specialized tool can access and remove the secured items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional screws are used, then ease of operation is improved, but security is worsened
Solution Approach 1:
The connector head features an asymmetric drive cavity shape that does not match conventional screwdriver profiles. This asymmetric design ensures that only a specifically shaped converter tool can engage and rotate the connector, preventing removal with standard tools while maintaining operational capability for authorized personnel.
Solution Approach 2:
The invention changes the geometric parameters of the connector head by incorporating a non-standard drive cavity shape. This parameter modification creates incompatibility with conventional tools, transforming the connector from a universally removable fastener into a secured fastener that requires a matching specialized tool.
2Reliability
If custom connectors with unconventional heads are used, then security is improved, but ease of operation is worsened
Solution Approach 1:
The converter tool serves as an intermediary device that bridges the gap between the custom connector head and standard tool interfaces. The converter engages with the asymmetric drive cavity of the connector and provides a conventional interface for standard screwdrivers, enabling authorized removal while maintaining security against unauthorized access.
Solution Approach 2:
The fastening system is segmented into distinct components: the custom connector with asymmetric drive cavity and the separate converter tool. This segmentation allows the connector to provide security through its unique head design while the converter provides the interface for authorized operation, separating the security function from the operational function.

AI summary
A system and method for securing an item. Custom connectors which only couple to a custom converter can secure an item, deter its theft, and prevent unauthorized access. The custom connectors have a custom head which has a custom void. The custom void has a unique shape which matches and couples with a custom converter. A custom converter allows the custom connector to be manipulated. If desired, subsequently, when the item is in a more secure location, conventional screws can replace the item.
