Solution Overview

Problem

Existing support elements for the human body, such as bicycle saddles and grips, are typically made in a standardized manner, failing to adapt to the specific anatomical and individual needs of users, necessitating a method for customization and personalization.

Innovation Solution

A method involving three-dimensional printing is used to create a support element with a first rigid support component and a second elastic padding component, featuring a honeycomb structure of cells with varying size, density, and stiffness based on user-specific pressure mapping, allowing for customized production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If standardized manufacturing methods are used for support elements, then production efficiency and cost are improved, but the ability to adapt to individual anatomical needs deteriorates

Engineering Contradiction:
Improveproduction efficiencyVSAvoidadaptability to individual anatomical needs
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by creating support elements with spatially varying properties - different regions of the support element have different densities, stiffness, and cellular structures tailored to specific anatomical requirements. The 3D printing process enables precise control of material distribution, allowing hard support in some areas and soft cushioning in others, directly addressing individual user anatomy while maintaining efficient production through digital modeling.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If customized support elements are created for each user, then adaptability to individual needs is improved, but manufacturing complexity and time increase

Engineering Contradiction:
Improvecustomization to user needsVSAvoidmanufacturing process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent utilizes parameter changes by modifying material properties (density, stiffness, cellular structure) and geometric parameters through 3D printing based on user-specific data. The digital model allows precise adjustment of structural parameters such as cell size, wall thickness, and material distribution, enabling customization without requiring complex manual manufacturing processes. The 3D printing technology translates digital parameters directly into physical properties, simplifying the manufacturing process while maintaining high adaptability.
