Custom Accessory Fitting Using 3D-Scanned Personal Molds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing products and accessories, such as grips and shoe inserts, are not designed for individual user needs, leading to suboptimal function and comfort due to a lack of personalized fit.
Innovation Solution
A method involving a user manipulating a malleable material to create a personalized mold, which is then scanned in 3D and modified to produce a custom accessory with attachments, ensuring a perfect fit and enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If generalized products are manufactured for average users, then manufacturing cost and complexity are reduced, but fit quality and user comfort deteriorate
Solution Approach 1:
The user performs preliminary actions by manipulating the malleable material mold block to form their own body contours before the actual manufacturing process. This preliminary shaping action captures the unique anatomical features, which are then used to create a precisely fitting custom accessory without requiring complex manufacturing processes.
Solution Approach 2:
The patent creates a copy of the user's body contours through the malleable material mold block that is manipulated to match the user's hand or foot shape. This physical copy is then scanned to create a digital model, which serves as the basis for manufacturing the custom accessory, ensuring precise fit while simplifying the manufacturing process.
2Productivity
If standardized accessories are produced, then production efficiency increases, but adaptability to individual user needs decreases
Solution Approach 1:
The user performs preliminary shaping actions with the malleable material to capture their unique body contours before manufacturing. This preliminary action enables customization without requiring complex post-manufacturing adjustments or retooling, maintaining high production efficiency while achieving personalized fit.
Solution Approach 2:
The patent changes the physical state of the material from malleable to hardened, and from physical form to digital 3D model. This parameter transformation allows the custom contours to be captured, stored, and reproduced efficiently, enabling personalized accessories to be manufactured with the same efficiency as standardized products.
3Reliability
If continuous contact between user and product is achieved through custom fitting, then stability and control are improved, but manufacturing complexity increases
Solution Approach 1:
The user performs preliminary manipulation of the malleable material to create the perfect fit before any manufacturing occurs. This preliminary action ensures continuous contact and optimal stability are achieved through proper contour matching, while the subsequent manufacturing process remains relatively simple using standard 3D scanning and additive manufacturing equipment.

AI summary
A method for developing personally fitting custom accessories is disclosed. The method for developing personally fitting custom accessories provides a way for a user to form a material in a personalized way to make a perfect fit. The perfect fit is achieved as a continuous form of contact between the user and an accessory, such as a hand grip. A mold is scanned in 3D so that a 3D model can be used to physical manufacture a personally fitting custom accessory or product. The method for developing personally fitting custom accessories also enables modification of a developed personally fitting custom accessory to provide enhance usability of the accessory (e.g., adding a mount to the top of a personally fitting custom hand grip, etc.). In this way, the method for developing personally fitting custom accessories establishes optimized stability, handling, control, and comfort for the end user.
