Shoe Vamp with Embroidered Loop Eyelets for Ventilation and Firmness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shoe vamps with protection eyelets lack firm connection to the vamp, ventilation, and straightness, and are not aesthetically pleasing or protective, with limited design options and simple interweaving patterns due to manual production methods.
Innovation Solution
A vamp with loop protection eyelets is created using a one-piece knitted fabric or sheet-splice-vamp, where strings are projected and embroidered to form loops on the shoe tongue part, reinforced with multiple layers of embroidery, and mechanized production methods ensure firm connection, ventilation, and rich design options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If protection eyelets are set by hand using protection eyelet string, then the process is flexible, but the connection is not firm and the product is not standardized
Solution Approach 1:
The patent replaces manual mechanical setting of protection eyelets with an automated embroidery machine system. The embroidery machine uses needle and thread to automatically stitch loops onto the vamp, transforming a manual mechanical process into an automated mechanical system that provides both standardization and firm connection through consistent, repeated stitching patterns.
Solution Approach 2:
The patent changes the operational parameters from manual hand-setting to automated machine embroidery with specific stitching patterns. The embroidery machine uses multiple layers of stitching (first layer forms loops, second layer covers and secures) with controlled thread tension and stitch density, creating firm connections that hand-setting cannot achieve consistently.
2Object-affected harmful factors
If mesh vamp is woven integrally with loops, then ventilation is improved, but the vamp becomes soft and loses straightness
Solution Approach 1:
The patent segments the vamp construction into two distinct parts: a mesh vamp body for ventilation and a reinforced shoe tongue part with embroidered loops for structure. The shoe tongue part uses multiple layers of embroidery stitching that create a stiffer, more structured area compared to the open mesh structure, allowing the vamp to maintain both ventilation and straightness in different regions.
Solution Approach 2:
The patent applies different structural qualities to different parts of the vamp. The mesh areas provide ventilation while the shoe tongue part with dense embroidery layers provides straightness and shaping ability. This local differentiation of material properties allows the overall vamp to achieve both ventilation and structural integrity simultaneously.
3Reliability
If multiple layers of embroidery are used to reinforce loops, then connection firmness is improved, but manufacturing complexity increases
Solution Approach 1:
The patent uses an automated embroidery machine to perform multiple layers of stitching without requiring manual intervention for each layer. The machine automatically completes the first layer (forming loops) and second layer (covering and securing) in a continuous automated process, transforming what would be complex manual multi-layer stitching into a simple automated operation.
Data Source
AI summary
A vamp with loop protection eyelets and a manufacture method thereof are disclosed. The vamp comprises a vamp body including a middle part having a notch which functions as a shoe tongue part. The vamp body is one-piece knitted fabric or a sheet-splice-vamp. Strings are projectively fixed on the upper surface of the vamp body. Threads embroider and fix the strings on the vamp body along a path of the length direction of the strings. The strings not only form a pattern on the vamp body but also leave loops on the shoe tongue part. Loops protrude inwards from both side edges of the shoe tongue part. The vamp has ventilation and has good supportability and straightness, is not only esthetic but also can protect feet. Protection eyelets are connected very firmly and do not come off easily. The pattern with a stereoscopic visual effect is formed on the vamp.
