Postural Platform Angled Foot Surface for Lateral Weight Redistribution

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Many individuals stand with uneven weight distribution, which can lead to poor posture and imbalance, as the body's weight is often directed medially rather than laterally, putting strain on the skeletal bones of the feet and ankles.

Innovation Solution

A postural platform with angled foot contact surfaces and rotational axes is designed to redistribute weight laterally, aligning the foot in a manner that supports the skeletal bones by tilting and rotating the top surface to specific angles, accompanied by visual indicia for proper foot placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the foot contact surface is positioned at a standard flat orientation parallel to the ground, then the device structure is simple, but the body weight is directed medially causing poor posture and strain on skeletal bones

Engineering Contradiction:

Improvedevice structure simplicityVSAvoidstrain on skeletal bones

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The foot contact surface is designed with an asymmetric angled orientation (11.25° tilt and 45° rotation) relative to the ground plane, deviating from the conventional flat parallel orientation. This asymmetric positioning redirects body weight laterally to the outer bones of the foot, resolving the contradiction by eliminating medial strain while maintaining structural feasibility through precise angular geometry

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The foot contact surface parameters are specifically changed from a standard flat orientation to an angled configuration with a 11.25° tilt and 45° rotation. This parameter modification transforms the weight distribution pattern, directing force laterally to strengthen skeletal bones while preserving device manufacturability through defined geometric specifications

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If the foot contact surface is angled and rotated to redistribute weight laterally, then posture and bone support are improved, but the device structure becomes more complex

Engineering Contradiction:

Improveposture qualityVSAvoiddevice structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The asymmetric angular positioning of the foot contact surface (11.25° tilt, 45° rotation) creates an optimized posture alignment that directs weight laterally, improving skeletal support without requiring complex mechanical systems. The simplicity of the asymmetric geometric configuration balances posture improvement with structural feasibility

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The foot contact surface is positioned in multiple angular dimensions simultaneously (11.25° tilt and 45° rotation), creating a three-dimensional orientation that optimizes weight distribution. This multi-dimensional positioning achieves superior posture support while maintaining device simplicity through precise angular geometry rather than complex mechanisms

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of operation

If weight is distributed evenly across the foot, then comfort is improved, but balance and skeletal strength are reduced

Engineering Contradiction:

ImprovecomfortVSAvoidskeletal strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

Instead of distributing weight uniformly across the entire foot, the angled foot contact surface concentrates weight locally on the outer bones of the foot through lateral redirection. This localized weight concentration strengthens skeletal structures while the angled surface geometry maintains overall balance, resolving the contradiction between comfort and strength

Inventive Principle:

Principle #3Local quality

4Stability of the object's composition

If the foot is aligned with the body's medial weight direction, then natural standing posture is maintained, but imbalance and weakness develop

Engineering Contradiction:

Improvestanding postureVSAvoidbalance

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

Instead of aligning the foot with the body's natural medial weight direction, the foot contact surface is inverted to a lateral orientation (45° rotation, 11.25° tilt). This inverted positioning redirects weight laterally to the outer bones, creating a new stable posture that actively prevents imbalance and strengthens skeletal structures, resolving the contradiction between posture maintenance and balance improvement

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

Disclosed herein are devices, systems and methods for redistributing the normal weight distribution of a user in a standing position. One example is a postural platform for either the left or right foot having a bottom surface defining a reference plane, a top surface configured as a foot contact surface and a perimeter side wall between the bottom and top surfaces. The top surface of the postural platform is rotated about a first rotational axis parallel to the reference plane and rotated about a second rotational axis orthogonal to the reference plane. In another example, a system includes first and second postural platforms that are independent of one another. In other example, the device is a sandal, shoe, sneaker or any foot covering with a tops surface being at a complex angle to a bottom surface. The top surface is tiled downwardly either to the left or right and turned either counter-clockwise or clockwise based on whether it is a respective left or right postural platform.
