Solution Overview

Problem

Existing jumping shoes lack stability and require a sporting degree to use safely, restricting natural movement and balance, and only provide limited additional jump height due to the size and design of the spring elements.

Innovation Solution

A jumping shoe design featuring a foot part with a flat support plate, a guide, and multiple energy storage elements connected via bearing shafts, allowing for reliable force absorption and redistribution, enhancing stability and enabling natural movement while providing increased jump height through optimized lever ratios and energy storage mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If a leaf spring with arcuate shape and lever arm mechanism is used, then jumping force is increased, but balance stability deteriorates

Engineering Contradiction:
Improvejumping forceVSAvoidbalance stability
Core Design Contradiction:
PowerVSStability of the object's composition

Solution Approach 1:

The jumping shoe divides the energy storage function into multiple separate spring elements (first spring element in the heel region, second spring element in the toe region) rather than using a single leaf spring. This segmentation allows independent optimization of each spring's function and position, improving both jumping force and balance stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a two-dimensional arcuate leaf spring to a three-dimensional arrangement with springs positioned at different locations (heel and toe) and orientations. The first spring element is arranged substantially perpendicular to the ground, while the second spring element has a specific angular orientation, creating a multi-dimensional force distribution system that enhances both power and stability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Power

If spring size is increased to improve jump height, then jumping performance is enhanced, but device complexity increases

Engineering Contradiction:
Improvejump heightVSAvoidspring arrangement complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

Instead of using one large complex spring, the patent segments the energy storage function into two smaller, simpler spring elements positioned at the heel and toe. Each spring can be optimized independently for its specific location, reducing overall device complexity while maintaining or enhancing jump height performance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different spring characteristics to different locations: the first spring element in the heel region is arranged substantially perpendicular to the ground for vertical force generation, while the second spring element in the toe region is oriented at a specific angle for forward propulsion. This local optimization allows each spring to be simple yet effective for its specific function.

Inventive Principle:
Principle #3Local quality

3Power

If a basic profile with foot plate and high-leg boot is used, then jumping power is increased, but ease of operation deteriorates

Engineering Contradiction:
Improvejumping powerVSAvoidnatural movement freedom
Core Design Contradiction:
PowerVSEase of operation

Solution Approach 1:

The patent uses flexible connection elements that allow dynamic movement between the jumping shoe components and the user's footwear. The connection elements can accommodate natural foot movements and adjustments while transmitting the necessary forces, making the device easier to operate without restricting natural gait or jumping motion.

Inventive Principle:
Principle #15Dynamics
