Customized Last Assembly Guidance for In-Store Production Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shoe production, especially in stores without access to three-dimensional printers, producing customized lasts can be time-consuming and inaccurate due to the lack of skilled personnel and appropriate equipment, leading to potential errors when assembling or adjusting multiple parts or processing objects.
Innovation Solution
A last production assisting apparatus and system that incorporates a camera, storage, processor, and display to image and calculate the positions and adjustments of parts, providing real-time guidance for accurate assembly or processing, potentially using augmented or virtual reality for enhanced visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a store clerk produces a last by assembling or adjusting multiple parts or processing an object without specialized equipment, then the last can be produced in a store setting, but the production time increases and accuracy decreases due to lack of skilled personnel and equipment
Solution Approach 1:
The patent introduces an image processing device as an intermediary tool between the store clerk and the last production process. The device captures images of the foot and parts, processes them to generate assembly guidance information, and presents it to the clerk. This intermediary system bridges the gap between unskilled personnel and precise last production, enabling accurate assembly without requiring specialized skills or equipment.
2Adaptability or versatility
If a store clerk produces a last by assembling or adjusting multiple parts or processing an object without specialized equipment, then the last can be produced in a store setting, but the production time increases due to trial and error
Solution Approach 1:
The system performs preliminary actions by pre-storing correct assembly information and using image processing to automatically generate guidance before the actual assembly takes place. The image processing device compares captured foot images with stored data to determine the correct assembly configuration in advance, then presents this pre-calculated guidance to the clerk. This eliminates the need for trial-and-error during the actual assembly process, significantly reducing production time.
3Manufacturing precision
If a store clerk produces a last by assembling or adjusting multiple parts or processing an object, then the last can be customized to fit the user's foot, but the process requires skilled personnel that may not be available in stores
Solution Approach 1:
The system enables self-service by allowing the image processing device to automatically perform the complex tasks of foot measurement, part selection, and assembly guidance generation without requiring skilled personnel. The device autonomously processes images, compares them with stored data, and generates step-by-step assembly instructions. This transfers the expertise from human operators to the automated system, making precise last customization accessible to unskilled store clerks.
