Solution Overview

Problem

Existing footwear systems fail to provide adjustable support in the metatarsal, arch, and heel regions, leading to discomfort and potential injury due to improper fit, as they do not accommodate varying foot shapes and dimensions, and require multiple insoles for different support configurations, increasing inventory and costs.

Innovation Solution

An adjustable insole system with slots for inserts in the metatarsal, arch, and heel regions, allowing users to customize support by choosing from various inserts of different thicknesses and angles, which can be combined to fit specific foot needs and activities, with optional covers to prevent debris entry.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple insoles with different support configurations are provided, then various foot support needs are met, but inventory costs and complexity increase significantly

Engineering Contradiction:
Improvesupport configuration varietyVSAvoidinventory complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The insole is divided into multiple modular regions (heel region, arch region, metatarsal region) that can be independently adjusted. Each region can have different support levels achieved through adjustable components, allowing customization without requiring multiple complete insole designs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insole incorporates adjustable components that allow users to dynamically change support characteristics. Elements such as adjustable arch support, heel cup depth, and metatarsal padding can be modified based on specific needs, providing versatility without increasing inventory complexity.

Inventive Principle:
Principle #15Dynamics

2Reliability

If custom-fitted insoles are provided for each individual, then optimal support is achieved, but cost and accessibility decrease

Engineering Contradiction:
Improvesupport effectivenessVSAvoidcustomization cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The insole system enables users to self-adjust support characteristics without requiring custom manufacturing. Through simple mechanical adjustments of modular components, individuals can customize fit and support levels to match their specific foot characteristics and needs.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The design allows modification of key parameters such as arch support height, heel cup depth, and metatarsal padding through adjustable mechanisms. These parameter changes enable customization of support effectiveness without requiring custom manufacturing for each user.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If fixed support insoles are used, then manufacturing is simple, but adaptability to different foot shapes and activities is limited

Engineering Contradiction:
Improveinsole manufacturing simplicityVSAvoidfoot shape accommodation
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The insole is constructed as a modular system with distinct adjustable regions (heel, arch, metatarsal) that can be independently configured. This segmentation maintains manufacturing simplicity while enabling adaptation to different foot shapes and activity requirements through component adjustment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adjustable insole design creates a universal product that can serve multiple functions and accommodate various foot types. A single insole model with adjustable components can adapt to different arch heights, heel volumes, and activity demands, replacing the need for multiple specialized insole designs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A removable and adjustable insert for footwear has slots placed in the insole and/or midsole of the shoe to allow access to the arch and/or metatarsal and/or heel regions of the insole and/or midsole. In an embodiment, an insert placed into the arch insert slot that establishes how much the arch protrudes above the remainder of the top surface of the insole. One or more inserts are provided having different thicknesses so that the height of the arch can be varied by the user or at the direction of a third party, such as a doctor or a trainer.
