Customizable Insole with Segmented Resilient Forefoot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insoles lack customization for different sports and foot types, leading to inadequate support and pressure distribution, which can result in discomfort and increased risk of injuries such as hairline and fifth metatarsal fractures.
Innovation Solution
A removable insole with a resilient layer featuring non-contiguous sections and subsections of varying hardness, integrated with medial and lateral arch support portions, and a detachable metatarsal cushion, designed to tailor the forefoot for specific sports by adjusting hardness levels and providing customized arch support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional insoles use uniform material and structure, then manufacturing is simple, but they cannot provide customized support for different sports and foot types
Solution Approach 1:
The insole is divided into multiple non-contiguous resilient layer sections and subsections with different hardness levels. Each section can be independently configured to provide customized support for specific foot areas, enabling adaptation to different sports and foot types without requiring complete redesign of the entire insole structure.
Solution Approach 2:
Different sections of the resilient layer are assigned different hardness levels (e.g., first level of hardness and second level of hardness that is softer) to match the specific support requirements of different foot areas. This allows localized optimization of support characteristics while maintaining overall structural integrity.
2Reliability
If conventional insoles lack pressure redistribution features, then structure is simple, but they cause discomfort and increase injury risk
Solution Approach 1:
The resilient layer is segmented into multiple non-contiguous sections and subsections that strategically distribute pressure across different foot areas. This segmentation enables effective pressure redistribution to prevent hot spots and reduce injury risk while maintaining a relatively simple overall insole structure.
Solution Approach 2:
The hardness parameter of the resilient layer is varied across different sections to optimize pressure distribution. By changing the hardness level in specific areas, the insole can redistribute pressure effectively to prevent injuries without adding complex mechanical structures.

AI summary
A removable insole for insertion into footwear, comprises a forefoot portion integral to the insole and extending at least to a metatarsal of a foot and including a resilient layer, the resilient layer including at least two non-contiguous resilient layer sections (including a big toe section). The at least two non-contiguous resilient sections include at least four resilient layer subsections in some embodiments, a continuous rear portion that includes a medial longitudinal arch support portion, a heel surrounding portion and a lateral longitudinal arch support portion; and a heel portion. In some embodiments, the forefoot is customizable by having different levels of hardness for the subsections and big toe section. The insole is therefore tailored a particular sport. The medial longitudinal arch support portion includes a detachable cushion configured to adjust a height of the medial longitudinal arch and to support the foot during pronation of the foot.
