Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fitness equipment is limited in functionality, allowing users to exercise only specific muscle groups, making workouts monotonous and lacking variety.
Innovation Solution
A sit-up bench apparatus with a base set, supporting rod sets, elastic sets, and an extending rod set that allows for diverse muscle exercises such as push-ups, stepping training, and leg lifting, utilizing elastic force and adjustable components for multiple exercise options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fitness equipment is used, then specific muscle exercise can be performed, but the exercise function is too simple and limited
Solution Approach 1:
The sit-up bench is designed with multiple supporting rod sets (first, second, and third supporting rod sets) that can be adjusted to different positions and angles, allowing the same equipment to perform various exercises including sit-ups, leg raises, push-ups, and incline exercises, thus achieving multi-functionality without requiring multiple separate pieces of equipment
Solution Approach 2:
The supporting rods are designed to be adjustable and reconfigurable, allowing users to change the position, angle, and configuration of the rods according to different exercise requirements. This dynamic adjustability enables the equipment to adapt to various exercise types and user needs, transforming a static structure into a versatile training system
2Adaptability or versatility
If single-function fitness equipment is used, then the equipment structure is simple, but the muscle training for the user is limited and monotonous
Solution Approach 1:
The equipment is divided into modular components including multiple supporting rod sets, each with adjustable positions and configurations. The first supporting rod set is disposed at one end, the second supporting rod set is disposed at another end, and the third supporting rod set connects these, creating segmented functional zones that can be independently adjusted for different exercise types
Solution Approach 2:
The supporting rods can be adjusted not only in position but also in angle and orientation, adding dimensional flexibility to the equipment. This allows the same physical structure to serve multiple exercise purposes by changing the spatial configuration of the rods, effectively using dimensional adjustment to increase functional variety
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
Enables users to perform a variety of exercises, including abdomen, arm, and leg workouts, enhancing muscle training diversity and preventing injury through elastic assistance and adjustable configurations.
Implementation Method 1
the body or the legs of the user can abut on the first cylinder to do muscle exercises such as push-up, stepping training, legs lifting, and so on with the assistance of the elastic force of the spring

AI summary
A sit-up bench apparatus includes a base set, two supporting rod sets, two elastic sets and an extending rod set. The base set includes a seat body and a pivotal base. The aperture is formed at one end of the pivotal base. The supporting rod set is pivotally disposed at the pivotal base and includes a supporting rod and a first cylinder. The first cylinder is connected with the supporting rod. The elastic set is disposed at the pivotal base and connected between the two supporting rod sets and the base set. The elastic set includes a spring and an extending rod set. One end of the spring is coupled to the pivotal base. The extending rod set is disposed in the aperture and includes a supporting wheel disposed at one end of the extending rod set.
