Hasp Seal Lock Assembly Tamper Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock assemblies for securing truck storage compartment latches and security seals are prone to tampering and loss of component parts, lacking a unitary design that ensures comprehensive protection.
Innovation Solution
A unitary lock assembly with a base member and cover member that overlay the latch, featuring cooperating cut-outs and apertures for clamping and locking, using a padlock for secure engagement, and optional tabs for easy operation, designed to prevent tampering and secure various types of security seals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional padlock is used to secure the latch hasp portions, then the latch can be locked, but the security seal can still be tampered with and component parts can be lost
Solution Approach 1:
The patent combines the latch hasp portions and security seal into a single integrated assembly that is locked together as one unit. The cover member encapsulates both the latch hasp portions and the security seal, preventing separate access or tampering with individual components. This merging ensures that if the assembly is locked, both the latch and seal are simultaneously secured against tampering and component loss.
Solution Approach 2:
The cover member serves multiple functions: it protects the latch hasp portions, secures the security seal, prevents tampering with either component, and maintains the integrity of the entire assembly. The single locking mechanism provides universal protection across all components within the assembly, eliminating the need for separate locking systems for each element.
2Reliability
If separate components are used for the latch and security seal, then each can be independently secured, but the risk of loss of component parts increases
Solution Approach 1:
The patent merges the latch hasp portions and security seal into a single integrated assembly enclosed by a cover member. This integration ensures that all components remain together as one unit, eliminating the risk of component parts being lost or separated. The single locking mechanism secures the entire assembly, preventing any individual component from being accidentally lost or misplaced.
3Reliability
If a unitary design is used for the lock assembly, then comprehensive protection is achieved, but the device complexity increases
Solution Approach 1:
The patent divides the lock assembly into distinct functional segments: a base member for attachment to the latch, a cover member for encapsulation and protection, and a locking mechanism for securing the assembly. This segmentation allows each component to perform its specific function while maintaining overall simplicity. The modular design makes the unitary structure easier to manufacture, assemble, and understand, reducing the practical complexity despite the comprehensive protection provided.

AI summary
A hasp seal lock assembly includes a base member that is attached via a hinge to a cover member. The cover member, when rotated such that the cover member engages the base member, is functionally adapted to overlay a latch and seal. The base member and the cover member each have a plurality of apertures defined in adjacent side walls that allow the horizontal latch arm to extend through the assembly. The base member and the cover member also include a second plurality of cooperating apertures whereby the base member and the cover member may be locked together by use of a padlock. In a first preferred embodiment, each cover side wall includes a tab and tab-receiving apertures are defined within the base member. The tabs require that the cover be lifted vertically prior to rotation of the cover member about the base member.
