Adjustable Insole with Arch Heel Acupressure Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoe insoles fail to effectively distribute weight evenly, leading to high pressure on the feet, which can cause issues like herniated disks and degenerative arthritis, and they cannot be adjusted to accommodate various foot shapes or heights, limiting their applicability.
Innovation Solution
A functional shoe insole with arch and heel stimulation members featuring acupressure modules made of elastic materials, allowing for adjustable intensity and height to match individual foot shapes, providing continuous stimulation during walking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a deep arch support accommodation part is formed in the midsole to accommodate the coil spring, then the elasticity and support function are improved, but the shoe cannot be applied to shoes with a thin midsole and the structure becomes more complex
Solution Approach 1:
The patent extracts the coil spring and support housing from the midsole structure and relocates them to the insole. This allows the arch support accommodation part to be formed in the insole rather than requiring a deep midsole structure, thereby reducing overall structural complexity while maintaining the elastic support function through the insole-based spring mechanism.
Solution Approach 2:
The patent divides the support system into separate functional modules: the insole with arch support accommodation part, the support housing, the coil spring, and the foot arch support. This segmentation allows each component to be optimized independently and simplifies the overall structure by distributing functions across multiple discrete elements rather than requiring a monolithic deep midsole structure.
2Strength
If multiple accessories such as foot arch support accommodation part, support housing, elastic coil spring, foot arch support, and foot arch support cover are provided, then the support function is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple support functions into an integrated insole assembly where the insole body, arch support accommodation part, and coupling mechanisms are merged into a single unified structure. This reduces the number of separate accessories needed while maintaining comprehensive support functionality through the integrated design.
Solution Approach 2:
The insole is designed with multi-functional capabilities: it provides structural support through the arch support accommodation part, elastic rebound through the coil spring, adjustable positioning through coupling holes, and comfort through the insole material itself. This multi-functionality eliminates the need for separate dedicated components for each function, reducing overall accessory count.
3Length of moving object
If the arch support accommodation part is formed in the midsole, then the elastic repulsion distance is sufficient, but it cannot be applied to shoes with a thin midsole
Solution Approach 1:
The patent implements a dynamic adjustment mechanism through coupling holes and coupling protrusions that allow the foot arch support to be positioned at different heights and depths within the support housing. This dynamic positioning capability enables the system to achieve sufficient elastic repulsion distance while adapting to shoes with varying midsole thicknesses, as the support can be configured to maximize available space in each specific shoe type.
Solution Approach 2:
The patent enables parameter changes in the support system by allowing adjustment of the foot arch support position, spring compression distance, and coupling depth. These parameter adjustments permit the system to achieve adequate elastic repulsion distance regardless of the host shoe's midsole thickness, thereby enhancing adaptability across different shoe types while maintaining sufficient functional distance.

AI summary
A functional shoe insole includes: a body part located inside a shoe, and configured to, when the shoe is worn by a user, come into direct contact with a sole of a foot of the user and distribute a load applied to the foot; an arch stimulation member coupled to the body part at a predetermined position, and configured to stimulate an arch portion of the sole of the foot of the user; and a heel stimulation member coupled to the body part at a predetermined position, and configured to stimulate a heel portion of the sole of the foot of the user. The arch stimulation member includes a first arch acupressure module. The heel stimulation member includes a first heel acupressure module.
