Seesaw Exercise Device With Segmented Grounding For Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seesaw exercise devices lack stability, causing users to feel uneasy and increasing the risk of falling, especially for elderly and sickly individuals. Additionally, these devices do not effectively engage the user's muscles, leading to boredom and insufficient training.
Innovation Solution
A seesaw exercise device with a rectangular base plate, a round bar attached along the longitudinal center line as a rotation fulcrum, and a pair of square bars attached to the base plate to reinforce the round bar. This configuration allows the base plate to perform a stable seesaw motion in the front-rear direction, with three grounded parts ensuring stability and preventing 360-degree swinging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hemispherical fulcrum portion is used for point contact with the ground, then the device can swing in all directions (360 degrees), but the user cannot stand stably and feels uneasy
Solution Approach 1:
The grounding function is segmented into three distinct contact points: the fulcrum portion and two ground contact portions positioned apart from each other. This segmentation transforms the single-point contact system into a multi-point contact system, providing both swinging capability and standing stability simultaneously.
Solution Approach 2:
The invention adds spatial dimension to the grounding configuration by positioning the two ground contact portions at specific distances from the fulcrum portion along the longitudinal center line. This dimensional arrangement creates a stable triangular grounding base when viewed from above, preventing unwanted rotation while allowing controlled seesaw motion.
2Adaptability or versatility
If the flat plate portion is inclined in any direction (360 degrees), then the device can change center of gravity, but the load for training is insufficient and users become bored
Solution Approach 1:
The device transitions from static instability to dynamic controlled motion. The seesaw mechanism allows the plate to incline only in the front-rear direction through controlled rotation about the fulcrum, creating dynamic training opportunities that engage muscles more effectively while maintaining safety.
Solution Approach 2:
The asymmetric positioning of the two ground contact portions relative to the fulcrum portion creates a seesaw mechanism that naturally produces rotational motion in the front-rear direction. This asymmetric grounding configuration enables effective training by allowing the user to shift weight and engage muscles during the controlled inclining motion.
3Device complexity
If no support base or frame is provided, then the device is simple and inexpensive, but the installation state is not stable and falling risk increases
Solution Approach 1:
The invention merges the support function with the plate structure itself. The round bar serving as the fulcrum and the two ground contact portions are integrated into the plate assembly, eliminating the need for separate support bases or frames. This merging maintains structural simplicity while achieving stable installation through the distributed three-point grounding configuration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a stable and firm installation state, reducing the risk of falling and allowing users of all ages and abilities to use it safely. The seesaw motion effectively engages the user's muscles, improving balance, stretching, and overall muscle strength.
Implementation Method 1
when the base plate is pushed down by a user, the base plate performs a seesaw motion in the front-rear direction with the round bar as a rotation fulcrum
Implementation Method 2
three parts including an arc surface portion of the round bar, a corner portion of each of the two square bars, and a corner portion of each of the long sides of the base plate, which are separated from one another, are grounded

AI summary
A seesaw exercise device includes: a base plate that is rectangular; a round bar that is fixed to a lower surface of the base plate along a longitudinal center line of the base plate in a manner of extending in a left-right direction, and a pair of square bars that are fixed to the lower surface of the base plate in a manner of holding the round bar therebetween in a front-rear direction, wherein when the base plate is pushed down by a user, the base plate performs a seesaw motion in the front-rear direction with the round bar as a rotation fulcrum, and three parts including an arc surface portion of the round bar, a corner portion of each of the two square bars, and a corner portion of the long side of the base plate, which are separated from one another, are grounded.
