Buckle Part Embedding Magnets for Durability and Aesthetics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buckle designs with magnetic components often have visible magnets, which can compromise aesthetics and durability, as well as pose challenges in manufacturing due to the risk of magnets falling off during the production process.
Innovation Solution
The buckle part incorporates an injection-molded portion that securely embeds a magnetic body, ensuring it is partially exposed only in specific surface regions, while being fully embedded in the injection-molded portion to prevent it from falling off. This design also simplifies the positioning structure of the mold device for injection-molding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the magnetic body is fully embedded in the injection-molded portion, then the magnetic body is prevented from falling off and durability is improved, but the magnetic body becomes completely invisible from the outside compromising aesthetics
Solution Approach 1:
The patent applies local quality by selectively exposing specific surface regions of the magnetic body while embedding other regions. The injection-molded portion covers portions of the magnetic body to prevent falling off, while leaving specific areas exposed to maintain aesthetic appearance. This creates a differentiated structure where different parts of the magnetic body have different visibility states, resolving the contradiction between complete embedding for durability and partial exposure for aesthetics.
2Reliability
If the magnetic body is securely embedded to prevent falling off, then reliability is improved, but the positioning structure of the mold device becomes more complex
Solution Approach 1:
The patent applies preliminary action by pre-forming recesses in the injection-molded portion that correspond to the surface regions of the magnetic body before the molding process. These recesses are designed in advance to receive and secure the magnetic body during injection-molding, eliminating the need for complex positioning structures. The recesses are formed as integral parts of the mold cavity, allowing the magnetic body to be automatically positioned and secured without additional positioning mechanisms.
3Shape
If the magnetic body is partially exposed at specific surface regions, then aesthetics are improved, but the risk of magnetic body falling off increases
Solution Approach 1:
The patent applies the nesting principle by placing the magnetic body within a recessed cavity formed in the injection-molded portion. The recesses are nested within the overall structure of the buckle part, creating a hierarchical arrangement where the magnetic body is contained within the recesses, which are themselves contained within the injection-molded portion. This nested structure provides secure embedding while allowing selective exposure of specific surface regions, resolving the contradiction between aesthetics and reliability.

Function Achieved in This Case
This solution effectively conceals the magnetic components, enhancing the buckle's appearance and durability. The secure embedding of magnets within the injection-molded portion prevents them from falling off during production, thereby simplifying the manufacturing process and extending the life span of the mold device's positioning structure.

AI summary
A buckle part includes: an injection-molded portion; and at least one magnetic body, optionally including a magnet secured in the injection-molded portion. The injection-molded portion is shaped such that the magnetic body is partially exposed in at least a first surface region of the magnetic body.
