Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional lock devices, such as hockey puck padlocks, lack tolerance for variations in hasp assemblies, making them incompatible with most existing setups, and expose lock handles and hinges, leaving them vulnerable to tampering. Additionally, existing security solutions are bulky, time-consuming to install, and require modifications that can damage the enclosure.

Innovation Solution

A portable lock device with a cylindrical casing that accommodates variations in hasp assemblies, providing a protective cover for lock handles and hinges without the need for modifications or fixed mounting, featuring a negative topography design with offset surfaces and raised edges to secure the lock assembly and prevent tampering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional hockey puck padlocks are used, then the lock device is simple in structure, but it has zero tolerance for accommodating variations in hasp assembly, making it incompatible with most existing hasp assemblies

Engineering Contradiction:

Improvecompatibility with hasp assembly variationsVSAvoidcasing structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The casing incorporates a bottom side with variable topography featuring multiple offset surfaces at different elevations that define reliefs. These geometric parameter variations allow the casing to accommodate different hasp assembly configurations and tolerances, enabling compatibility across various hasp types while maintaining a unified casing structure

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The bottom side of the casing is segmented into multiple offset surfaces that can independently engage with different portions of the hasp assembly. This segmentation allows each surface to adapt to specific geometric variations in the hasp, providing flexibility without requiring complete redesign of the entire locking mechanism

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If conventional hockey puck padlocks are used, then the lock device is easy to operate, but the lock assembly components remain exposed and vulnerable to tampering

Engineering Contradiction:

Improvevulnerability to tamperingVSAvoidcasing structure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The casing merges the functions of protecting the lock cartridge with covering and protecting the lock assembly components (handle, hinge, hinge pin). By integrating these protection functions into a single casing structure with appropriate topography, the design eliminates the need for separate protective covers while comprehensively securing all vulnerable components

Inventive Principle:

Principle #5Merging (Combining)

3Object-affected harmful factors

If conventional covers are used to cover the lock assembly, then the lock assembly is protected from tampering, but the covers are bulky, time consuming to install and remove, and add weight and cost

Engineering Contradiction:

Improveprotection from tamperingVSAvoidinstallation and removal time

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The casing is designed as a universal multi-functional component that simultaneously serves as the lock device housing, the protective cover for the lock assembly, and the interface with the hasp. This eliminates the need for separate protective covers and integrates all protection functions into the primary locking mechanism, reducing installation time and removing the need for additional components

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The casing is designed to be dynamically attachable and removable from the hasp assembly, allowing quick installation and removal without permanent modifications. The bottom side topography enables the casing to adapt to different hasp configurations while maintaining secure attachment during use, providing both protection and operational flexibility

Inventive Principle:

Principle #15Dynamics

4Object-affected harmful factors

If conventional covers are used to cover the lock assembly, then the lock assembly is protected from tampering, but additional weight and cost are added

Engineering Contradiction:

Improveprotection from tamperingVSAvoidlock device weight

Core Design Contradiction:

Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

The protective cover function is merged into the casing itself rather than being a separate component. The casing's bottom side topography provides the protective coverage for lock assembly components while maintaining the structural efficiency of a single integrated piece, eliminating the additional weight that would result from layered protective covers

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A casing that has a generally cylindrical configuration having a bottom side that includes a bottom side cavity. The bottom side has a topography that is generally a negative topography of a surface of an article with which the bottom side associates. The topography of the bottom side is defined by a plurality of offset surfaces that define raised edges, with the offset surfaces and resulting raised edges forming reliefs.
