Solution Overview

Problem

Conventional gymnastics springboards have fixed elasticity, which cannot be adjusted, limiting the gymnast's ability to customize the feel and response based on different jumps and locations.

Innovation Solution

A gymnastics springboard with a movable elastic device that includes a driving wheel, driven wheel, and flexible link, allowing for rotational movement to adjust the elasticity by sliding the upper and lower plates, enabling easy modification of the springboard's elasticity through a single movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the elastic members are fixed in the springboard, then the structure is simple and stable, but the elasticity cannot be modified

Engineering Contradiction:
Improveelasticity adjustabilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the elastic members movable rather than fixed. The elastic members can slide along the longitudinal axis of the springboard between the upper and lower parts, allowing the elasticity characteristics to be adjusted dynamically. This resolves the contradiction by enabling elasticity modification without requiring a completely fixed rigid structure, as the movable design maintains structural integrity while providing adjustability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies segmentation by dividing the springboard into distinct components: upper part, lower part, and elastic members that can move independently between them. This segmentation allows each component to perform its specific function while enabling the elastic members to be repositioned along the longitudinal axis to adjust elasticity characteristics without affecting the overall structural stability.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the elastic members are movable to adjust elasticity, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improveelasticity customizationVSAvoidadjustment simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies the self-service principle by enabling the gymnast to directly adjust the position of the elastic members themselves. The elastic members are designed with features that allow them to be easily grasped and repositioned by the user without requiring additional tools or complex mechanisms. This resolves the contradiction by making the adjustment process simple and intuitive, allowing gymnasts to customize elasticity characteristics independently.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If a complex mechanism is used to move the elastic device, then the adjustment precision is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improveelasticity control precisionVSAvoidadjustment effort
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent applies mechanics substitution by replacing complex mechanical transmission mechanisms with a direct manual adjustment system. Instead of using gears, belts, or other intermediary mechanical components to move the elastic members, the design allows gymnasts to directly reposition the elastic members along the longitudinal axis. This resolves the contradiction by eliminating unnecessary mechanical complexity while maintaining precise control over elasticity characteristics through direct user manipulation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
