Solution Overview

Problem

Existing footwear inserts fail to adequately accommodate varying foot widths and shapes, leading to discomfort and the need for multiple shoe sizes, which increases cost and shelf space, while contoured inserts may not provide sufficient support for individual foot needs.

Innovation Solution

An adjustable footbed system with a removable arch support and complementary recess in the footbed, allowing for customizable arch support through interchangeable layers of varying hardness and density, enabling users to adjust support levels based on foot shape and comfort preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If contoured orthopaedic inserts are used to support the entire foot, then foot alignment and comfort are improved, but manufacturing cost and price to consumer increase significantly

Engineering Contradiction:

Improvefoot alignment and comfortVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The footbed is divided into multiple functional zones: a heel region, a midfoot region with a recess, and a forefoot region. This segmentation allows each zone to be optimized independently for its specific function while using simpler, less expensive materials and manufacturing processes for each segment rather than requiring complex full-foot contouring.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The arch support function is extracted from the main footbed structure and implemented as a separate removable insert that fits into a recess in the midfoot region. This allows the arch support to be provided as a simple, inexpensive component rather than requiring the entire footbed to be contoured, significantly reducing manufacturing complexity and cost.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If a range of comfort shoes with different widths are provided, then feet of varying widths are accommodated, but cost and shelf space requirements increase

Engineering Contradiction:

Improveaccommodation of varying foot widthsVSAvoidinventory range and shelf space

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

A single standard-width footbed design is made universally adaptable to different foot widths through the use of interchangeable inserts. The footbed includes a recess that can accommodate different arch support inserts, and the forefoot region can accommodate different width configurations, allowing one footbed model to serve multiple width requirements without needing separate inventory for each width.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The footbed system allows dynamic adjustment of its characteristics through removable and interchangeable inserts. Users can change the arch support insert or forefoot configuration to match their specific foot width and comfort needs, transforming a static product into an adaptable system that responds to individual requirements without requiring multiple fixed variants.

Inventive Principle:

Principle #15Dynamics

3Reliability

If full length contoured inserts are used to accommodate foot shape changes, then support is maintained, but cost increases and size variation range is limited

Engineering Contradiction:

Improvesupport consistencyVSAvoidsize variation range

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The footbed is segmented into distinct regions (heel, midfoot with recess, forefoot) that can be independently adjusted. This segmentation allows selective modification of specific zones to accommodate foot shape changes throughout the day without requiring replacement of the entire insert, maintaining support while expanding adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The removable arch support insert and interchangeable forefoot configurations enable the footbed to dynamically adapt to changing foot conditions. Users can swap inserts to accommodate swelling or shape changes, providing continuous support across a wider range of foot states than fixed contoured inserts.

Inventive Principle:

Principle #15Dynamics
