Solution Overview

Problem

Over pronation and supination of the foot lead to discomfort and injuries such as arch pain, heel pain, and joint pain, as existing orthotic devices fail to effectively correct these issues.

Innovation Solution

An orthotic device with a removable angle insert that can be attached to the insole to adjust the angle of the foot, specifically increasing the angle on the medial side for pronation and the lateral side for supination, providing customizable support to correct foot alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing orthotic devices are used, then foot support is provided, but they fail to effectively correct over pronation or supination

Engineering Contradiction:

Improveeffectiveness in correcting foot alignmentVSAvoidcustomizability of angle adjustment

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The orthotic device is divided into modular components: a base insole and separate angle inserts. The angle inserts can be detached and replaced to adjust the correction angle, allowing customization while maintaining reliable foot alignment correction through the structured design of each component

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The orthotic device transitions from a static insole to a dynamic system by introducing removable angle inserts. This allows the correction angle to be adjusted based on the user's specific needs, enhancing adaptability while each insert maintains reliable structural support for correcting foot alignment

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a fixed angle insole is used, then manufacturing is simple, but it cannot be customized for different pronation or supination needs

Engineering Contradiction:

Improvecustomizability of angleVSAvoidstructure with removable inserts

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By segmenting the orthotic device into a base insole and separate angle inserts, the system achieves customizability without excessive complexity. Each component is relatively simple in design, but their combination provides adaptable angle adjustment for different foot conditions

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base insole serves as a universal platform that can work with multiple different angle inserts. This multi-functionality allows a single base design to support various correction angles, achieving adaptability without proportionally increasing overall device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An orthotic device (100) for insertion into footwear for correcting over pronation or supination of a foot is disclosed. The orthotic device (100) may include an insole (102) comprising an upper surface (112) and a lower surface (114). The upper surface (112) of the insole (102) may receive and support at least a portion of the foot. The orthotic device (100) also may include a removable angle insert (130) attachable to the lower surface (114) of the insole (102). The removable angle insert (130) may increase an angle about a side of the insole (102) to correct over pronation or supination of the foot.
