Innovation Solution
A vertical knee raise machine with a tripod base that can be easily folded and adjusted, featuring a backrest at an oblique angle, retractable armrests, and a support shaft that allows for compact storage, enabling quick deployment and storage without the need for knobs or tedious assembly processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional vertical knee raise machines are designed for stability and strength, then they can handle gym-level loads and stress, but they become bulky and cannot be conveniently stored in home environments
Solution Approach 1:
The machine is divided into separable components including a base unit with support shaft and a backrest assembly with armrests. These segments can be connected or separated via quick-connect mechanisms, allowing the device to be configured for strength during exercise and compactness for storage by separating the components.
Solution Approach 2:
The base and backrest assembly feature movable connections that allow dynamic reconfiguration. The quick-connect mechanisms enable the structure to transition between a stable, extended configuration for exercise and a compact, folded configuration for storage, adapting the device's form based on usage needs.
2Stability of the object's composition
If vertical knee raise machines are designed to be sturdy and stable, then they can withstand exercise stress, but they become heavy and difficult for individuals to move and set up
Solution Approach 1:
By segmenting the machine into movable components connected by quick-connect mechanisms, the overall weight is distributed across separate parts that can be easily maneuvered. This allows individuals to move and assemble the device without requiring assistance, while the assembled configuration maintains structural stability during exercise.
Solution Approach 2:
The dynamic quick-connect mechanisms enable the structure to be easily reconfigured and moved when disassembled, reducing the effective weight burden on the user. When assembled, the same mechanisms provide stable connections that maintain structural integrity during exercise, thus resolving the contradiction between portability and stability.
3Stability of the object's composition
If vertical knee raise machines are designed with fixed structures, then they provide stability during exercise, but they cannot be quickly folded for storage
Solution Approach 1:
The quick-connect mechanisms provide dynamic functionality, allowing the structure to be rapidly assembled and disassembled without compromising stability during exercise. The mechanisms enable the device to transition quickly between stable and compact configurations, eliminating the time loss associated with traditional assembly while maintaining exercise stability.
4Adaptability or versatility
If vertical knee raise machines use traditional assembly mechanisms like knobs, then they can be adjusted, but they become tedious to assemble and disassemble
Solution Approach 1:
The quick-connect mechanisms replace traditional static assembly methods like knobs with dynamic, tool-free connection systems. These mechanisms provide adjustable and adaptable connections that are much easier to operate, allowing users to quickly assemble and disassemble the device without the tedium of traditional assembly while maintaining the necessary adjustability for different exercise configurations.
