Adjustable Footbed System With Removable Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The footwear industry faces challenges such as incorrect fit leading to high return costs, inventory issues due to half sizes and varying foot morphologies, disparate sizes between feet, and the need for dynamic sizing across different activities, which existing technologies fail to address effectively.
Innovation Solution
An adjustable footbed system comprising a footbed and a removable foot support with a bumper that can be positioned over the upper or lower surface of the footbed, secured using adhesion or hook and loop fasteners, allowing for size, fit, and comfort adjustments by providing additional height and thickness through a bumper that can be tapered for comfort and secured to the footbed with interlocking features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a shoe is designed to fit a specific foot size, then the manufacturing precision is improved, but the adaptability deteriorates when foot morphology changes
Solution Approach 1:
The footbed system incorporates adjustable components including a removable foot support and bumper that can be repositioned or removed to dynamically adapt the shoe fit to changing foot morphology, transforming a static fit system into a dynamic one
Solution Approach 2:
The footbed is divided into modular components including a removable foot support and adjustable bumper, allowing independent adjustment of different footbed sections to accommodate various foot shapes and sizes while maintaining overall system functionality
2Adaptability or versatility
If multiple shoe sizes are manufactured to accommodate different foot sizes, then the adaptability is improved, but the device complexity and inventory requirements increase
Solution Approach 1:
A single shoe design incorporates a universal footbed system with adjustable components that can accommodate multiple foot sizes and morphologies through reconfiguration, eliminating the need for multiple dedicated shoe sizes and reducing inventory complexity
Solution Approach 2:
The footbed system allows dynamic reconfiguration through removable and repositionable components, enabling the same shoe to adapt to different foot sizes and morphologies over time, reducing the need for extensive inventory
3Adaptability or versatility
If a footbed system includes adjustable components, then the adaptability is improved, but the ease of operation deteriorates due to additional adjustment mechanisms
Solution Approach 1:
The adjustment mechanism is segmented into simple, independent components (removable foot support, bumper) that can be individually adjusted without complex mechanisms, maintaining ease of operation while providing adaptability
Solution Approach 2:
The footbed system incorporates self-adjusting features such as elastic materials and simple mechanical components that allow users to easily modify the fit without requiring complex tools or procedures
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible sizing and comfort adjustments in shoes, accommodating larger sizes and addressing morphological changes, such as foot growth, injury, or pregnancy, by allowing interchangeable foot supports, thereby reducing returns and inventory complexities.
Implementation Method 1
the bumper has a bumper height greater than a height of the footbed
Implementation Method 2
the removeable foot support is tapered at or toward an edge of the removeable foot support in contact with the footbed
