Removable Shackle Padlock with Pivoting Rear Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional padlocks have a single standard-sized shackle that cannot be removed or replaced, limiting their applicability to objects of varying sizes and shapes, resulting in consumers needing to purchase multiple padlocks with different shackle sizes, which is wasteful and reduces market acceptance.
Innovation Solution
A padlock design featuring a removable shackle that can be changed to accommodate different sizes and shapes, comprising a housing with a pivoting rear cover, a sliding groove system, a locking member, and a spring mechanism that allows the shackle to be easily detached and replaced, enabling wider applicability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shackle is designed as a fixed single size and standard structure, then the padlock structure is simple and reliable, but the applicability to objects of different sizes and shapes is limited
Solution Approach 1:
The shackle is divided into multiple segments or sections that can move relative to each other, allowing the shackle to change its overall shape and size while maintaining structural integrity. This segmentation enables the shackle to adapt to different locking scenarios without requiring multiple different shackles.
Solution Approach 2:
The shackle incorporates dynamic elements such as telescopic sections, articulating joints, or expandable structures that allow it to change its configuration from a compact state to an extended state, providing versatility for different object sizes while maintaining a simple stored form.
2Adaptability or versatility
If the shackle is designed as a fixed single size, then the padlock manufacturing cost is low, but consumers need to buy multiple padlocks for different objects resulting in money waste
Solution Approach 1:
The shackle is designed to perform multiple functions by changing its configuration - it can be extended for large objects, compressed for small objects, and adjusted to different shapes, making a single padlock universally applicable to various locking needs that previously required multiple specialized padlocks.
3Adaptability or versatility
If the shackle is designed as a fixed standard structure, then the padlock is simple to manufacture, but the shackle cannot be replaced to correspond to objects with different sizes and shapes
Solution Approach 1:
The shackle is divided into modular segments that can be independently manufactured and then assembled together in different configurations, allowing for easy replacement and reconfiguration to match different locking requirements while maintaining manufacturing simplicity through standardized components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The padlock with a removable shackle can be adapted to various object sizes, reducing the need for multiple padlocks and increasing consumer acceptance by eliminating the need for multiple shackle standards, thereby enhancing its market viability and user convenience.
Implementation Method 1
a spring, the spring is located in the sliding groove and arranged between the locking member and the limiting member

AI summary
A padlock comprises a housing, a shackle, a locking member, and a limiting set. The housing has a front cover and a rear cover which is pivoted at the front cover. The rear cover has a sliding groove. The rear cover which corresponds to the sliding groove has a through hole and a locking hole. A penetrating groove is formed at the sliding groove. The shackle has a pivoting portion which passes through the through hole and moved toward the cavity. The locking member is slidably arranged in the sliding groove and limited by or separated from the locking portion of the shackle. The limiting set has a limiting member and a releasing member. The limiting member includes an entry slot, an embedded end, and an inclined surface. The limiting member is slidably arranged in the sliding groove. The releasing member is slidably arranged in the penetrating groove.
