Adjustable Padlock with Combination Lock for Bags
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 adjustment and locking on various elements, including bags and backpacks, without the need for keys, and includes securing means to attach the locked item to a fixed or mobile structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
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 reliability and ease of operation.
2Ease of manufacture
If a fixed-size padlock is used, then the manufacturing simplicity is maintained, but the adaptability deteriorates because it cannot fit different sized openings or elements
Solution Approach 1:
The patent incorporates an adjustable enclosure mechanism that allows the padlock to dynamically change its size and shape to accommodate different openings and elements. This dynamic adjustment capability is achieved through movable components that can be reconfigured, resolving the contradiction between manufacturing simplicity and adaptability.
Solution Approach 2:
The padlock is divided into separate adjustable components including movable walls and enclosure segments that can be independently positioned. This segmentation allows the padlock to adapt to various sizes while maintaining a relatively simple manufacturing process for each individual component.
3Strength
If the padlock enclosure is made rigid and fixed, then the structural strength is improved, but the ease of operation deteriorates due to difficulty in adjustment
Solution Approach 1:
The patent employs a dynamic adjustment mechanism where the enclosure components can move smoothly between locked and adjusted positions. The mechanism uses controlled movement of walls and segments that maintain structural integrity during adjustment, resolving the contradiction between strength and ease of operation.
Solution Approach 2:
The adjustment mechanism replaces complex mechanical linkages with a more streamlined system that uses the combination lock mechanism itself to control the movement of enclosure components. This substitution simplifies the adjustment process while maintaining the rigidity needed for strength.

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.
