Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a torsion spring is used in the abdominal exercise wheel, then the exercise function is provided, but the torsion outputs are unstable and the springback noise is large
Solution Approach 1:
The patent replaces the traditional torsion spring with a rubber elastic element. This substitution changes the mechanical system from a metal spring-based torsion mechanism to an elastomer-based system. The rubber elastic element provides stable elastic force output and significantly reduces springback noise, directly resolving the contradiction between reliability and harmful factors.
Solution Approach 2:
The patent uses rubber material as the elastic element, utilizing the composite properties of elastomers. The rubber material provides both the necessary elastic force for exercise and the damping characteristics to reduce noise, simultaneously addressing both the stability and noise issues.
2Adaptability or versatility
If no resistance adjustment function is provided, then the device structure is simple, but it cannot meet requirements of users at different exercise stages
Solution Approach 1:
The patent introduces an adjustable resistance mechanism that allows users to dynamically change the exercise intensity according to their progress. The resistance can be adjusted by changing the position of the friction pad or adding/removing weights, making the device adaptable to different exercise stages while maintaining a relatively simple overall structure.
Solution Approach 2:
The device incorporates multiple functions including resistance adjustment, stroke adjustment, and exercise tracking into a single abdominal exercise wheel. This multi-functionality approach allows one device to serve users at different exercise stages without requiring multiple separate devices, balancing adaptability with structural efficiency.
3Object-affected harmful factors
If no stroke adjustment function is provided, then the device structure is simple, but uncontrolled motion may cause facial injury
Solution Approach 1:
The patent incorporates an adjustable stroke limitation mechanism that allows users to set the maximum rotation distance of the wheel. This dynamic adjustment capability prevents uncontrolled motion that could cause facial injury, while allowing flexibility for different exercise levels. The mechanism typically involves an adjustable stop or limiter that can be positioned at different distances.
4Loss of information
If no exercise tracking function is provided, then the device structure is simple, but functions of counting times and recording consumed calories are not available
Solution Approach 1:
The patent replaces complex mechanical counting mechanisms with electronic sensors and a microcontroller system. The sensor detects wheel rotations and the microcontroller calculates and stores exercise data including repetition count and calorie consumption. This electronic approach provides accurate tracking functionality while keeping the overall device structure relatively simple and compact.
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 adjust resistance and stroke length, tracks exercise times and calorie consumption, reduces noise and facial injury risk, and meets varying exercise requirements, enhancing user experience and safety.
Implementation Method 1
the power spring forms a rotating torque to store energy; when the motion component rotates inward, the power spring releases energy
Implementation Method 2
The buffer member can perform a buffer action when the stroke locating member touches the spiral groove of the main body, reducing noise during springback of the power spring
Implementation Method 3
The main body is fixedly provided with the sensor. The sensor is disposed close to the spiral groove on a side of the main body, and can sense a motion of the stroke locating member
