Multi-layer decorative vamp hot pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for decorating shoe vamps require significant manual labor and result in increased manufacturing costs due to the need for sewing small or complex ornaments, which is inconvenient and costly.
Innovation Solution
A method involving cutting a base and two plates to predetermined shapes, arranging them in a specific order, stacking them with the first plate between the base and the second plate, and hot pressing to connect them, eliminating the need for sewing and allowing for accurate, convenient, and cost-effective production of multi-layer decorative vamps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sewing is used to attach ornaments to the vamp, then the ornament can be attached to the vamp, but a large amount of manual labor is required and manufacturing costs increase
Solution Approach 1:
The patent replaces the mechanical sewing process with a hot-pressing process. The vamp is formed by hot-pressing a composite structure consisting of a base fabric layer and a decorative layer with integrated patterns, eliminating the need for manual or automated sewing operations to attach ornaments.
Solution Approach 2:
The patent merges the ornament attachment process with the vamp formation process itself. The decorative layer is integrated into the vamp structure through hot-pressing, so that the ornament becomes part of the vamp rather than a separate component requiring additional attachment steps.
2Ease of operation
If outlet seams are reserved for sewing small or complex ornaments, then the ornaments can be sewn on the vamp, but the process becomes inconvenient and manufacturing costs increase
Solution Approach 1:
The patent replaces the sewing operation requiring outlet seams with a hot-pressing operation. The decorative layer is bonded to the base layer through heat and pressure, eliminating the need for seam openings and subsequent sewing operations for attaching ornaments.
3Reliability
If sewing is used to attach ornaments, then the ornament can be secured to the vamp, but the process requires outlet seams that complicate the design
Solution Approach 1:
The patent replaces mechanical sewing attachment with thermal bonding through hot-pressing. The decorative layer and base layer are bonded together through heat and pressure, providing secure attachment without requiring outlet seams or complex stitching patterns.
