Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional buckles used in the pet industry fail to meet the high impact resistance and durability requirements due to their weight and structural limitations, often breaking under pet hyperactivity and becoming inconvenient to open over time.
Innovation Solution
A lightweight buckle design featuring a plastic shell with a lock core that includes a horizontal socket, cylindrical mounting slot, guiding block, and interdigitating lock blocks with springs, which disperses strength and allows for easy opening after impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an all-metal structure is used to improve impact resistance, then strength is improved, but weight increases and ease of operation deteriorates
Solution Approach 1:
The buckle combines plastic material for the shell with metal components (lock core, springs, lock blocks) to create a composite structure. The plastic shell provides lightweight construction while the metal lock core with interdigitating lock blocks provides the necessary impact resistance and locking strength, resolving the contradiction between weight and strength.
Solution Approach 2:
The lock core is divided into multiple lock blocks (first lock block, second lock block, third lock block) that can move independently. This segmentation allows each block to respond to impact forces separately, distributing the load and preventing single-point failure, while maintaining overall lightweight construction.
2Ease of manufacture
If a traditional buckle structure is used, then ease of manufacture is maintained, but reliability deteriorates under impact
Solution Approach 1:
The lock core is segmented into multiple independent lock blocks that can be manufactured separately and then assembled. This allows each component to be optimized for its specific function while maintaining overall manufacturability. The segmented structure also improves reliability by distributing impact forces across multiple independent elements.
Solution Approach 2:
The lock blocks are designed to be movable rather than fixed, allowing them to dynamic response to impact forces. The springs enable the lock blocks to move and absorb impact energy, while still maintaining the locking function. This dynamic design improves reliability without significantly complicating the manufacturing process.
3Device complexity
If a traditional buckle structure is used, then device complexity is maintained, but ease of operation deteriorates over time
Solution Approach 1:
The lock blocks are designed to be movable with spring mechanisms, allowing them to dynamically respond to opening forces. This dynamic design maintains ease of operation over time by preventing stiffness accumulation, while the overall structure remains relatively simple and manageable.

AI summary
An improved buckle includes a plastic shell, an inserting element, and a lock core. A horizontal socket fitting with the inserting element and a cylindrical mounting slot for mounting the lock core are formed on the plastic shell, the cylindrical mounting slot communicating with the horizontal socket. The horizontal socket includes a guiding block, and the inserting element includes an inserting piece for inserting into the horizontal socket to cooperate with the lock core, with two triangular notches symmetrically and a guiding groove cooperating with the guiding block formed thereon. The buckle has advantages of a simple structure and a reasonable design, and may realize the dispersion of the strength by utilizing the special structure of the lock core, so the structural strength gets ensured, and meanwhile the buckle may be kept light-weighted, and thus the buckle is suitable for the pet industry.
