Adjustable Padlock With Combination Lock And Resistant Mesh Receptacle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security solutions for personal belongings, such as bags and backpacks, are either not secure, cumbersome, or require the use of keys, making them inadequate for preventing theft when left unattended in public places.
Innovation Solution
An adjustable padlock with a combination mechanism that allows secure attachment to objects like bags, bicycles, or other structures, without the need for keys, and a security receptacle made of a resistant mesh material that resembles everyday bags, providing additional protection against theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional key-based lock is used, then the locking function is provided, but the ease of operation deteriorates due to the need to carry and manage keys
Solution Approach 1:
The patent replaces the traditional key-based mechanical locking system with a combination mechanism that uses a sequence of numbers or symbols to unlock the padlock. This substitution eliminates the need for physical keys while maintaining the locking function, directly resolving the contradiction between ease of operation and reliability.
2Adaptability or versatility
If a fixed-length cable is used, then the structure is simple, but the adaptability deteriorates because it cannot fit different sized objects
Solution Approach 1:
The patent implements a cable with variable length that can be extended or retracted as needed. This dynamic adjustment capability allows the padlock to adapt to different sized objects and configurations, achieving versatility without requiring multiple different padlocks, while the internal mechanism remains relatively compact.
Solution Approach 2:
The cable is designed to be stored within the padlock body when not in use, creating a nested configuration. This allows the cable to be extended when needed for different applications while maintaining a compact form factor when retracted, balancing adaptability with structural simplicity.
3Strength
If ordinary material is used for the receptacle, then it looks like everyday bags, but the strength deteriorates making it vulnerable to cutting tools
Solution Approach 1:
The patent employs composite construction for the receptacle, combining steel mesh for structural strength and cut resistance with fabric or flexible material coverings for aesthetic appearance. This composite approach achieves both high strength against cutting tools and ease of manufacture through modular assembly, resolving the contradiction between strength and manufacturing simplicity.

AI summary
Adjustable padlock, security receptacle and system. The present invention relates to a locking device which can be securely adjusted on an object to prevent the padlock from being able to become separated from said object unless a specific combination of a combination mechanism incorporated in the padlock is used and releases the padlock without requiring the use of keys. Said object preferably relates to a security receptacle formed by a flexible mesh which preferably incorporates an internal covering and an external covering consisting of fabric or another flexible material making it look like a bag, backpack or sack. The mesh is preferably made of steel and is molded and treated to have the shape of the receptacle, i.e., of bag, sack or backpack. The combination of said adjustable padlock and receptacle gives rise to a receptacle system with a security lock.
