Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed bike trainer is used for strength training, then the training effect is improved, but the fatigue wear of the bike connection position increases and safety hazards occur
Solution Approach 1:
The patent introduces a dynamic support structure that can move forward and backward along the length direction of the flat plate, allowing the trainer stand to adapt to the dynamic forces generated during cycling. This dynamic movement distributes the stress away from fixed connection points, reducing fatigue wear while maintaining training effectiveness
Solution Approach 2:
The support structure's position parameter is made variable, allowing it to move along the flat plate in response to cycling forces. This parameter change enables the system to absorb and distribute dynamic loads, preventing concentrated stress at fixed connection positions and extending component lifespan
2Adaptability or versatility
If an adjustable air bag rocker plate is used, then the adaptation to different weight ranges is improved, but the simulation of forward movement feedback is insufficient
Solution Approach 1:
The patent incorporates a support structure that can dynamically move forward and backward along the flat plate, creating realistic feedback that simulates the forward movement sensation during cycling. This dynamic element complements the existing weight-adaptation capability, providing both versatility and authentic movement feedback
Solution Approach 2:
The support structure is designed as a separate, movable component that operates independently from the weight-adjustment mechanism. This segmentation allows the forward movement feedback function to be added without compromising the existing weight range adaptation capability
3Ease of operation
If a leaf spring pressing wheel with arc guide rail is used, then the force feedback effect is improved, but the structure complexity and cost increase
Solution Approach 1:
The patent uses a flexible flat plate as the base structure, which inherently provides force feedback through its elastic deformation. This flexible membrane approach replaces complex rigid mechanisms like leaf springs and arc guide rails, achieving force feedback with simpler, more cost-effective components
Solution Approach 2:
The patent substitutes complex mechanical force feedback mechanisms (leaf springs, pressing wheels, arc guide rails) with a more simple elastic support structure that provides comparable or superior feedback through material elasticity and dynamic movement, reducing overall system complexity
4Ease of operation
If an arc guide rail force feedback structure is used, then the left and right inclination feedback is improved, but the vertical center of gravity movement occurs which is inconsistent with actual cycling
Solution Approach 1:
The support structure moves dynamically along the flat plate in a horizontal direction, providing inclination feedback without causing vertical center of gravity movement. This dynamic horizontal movement mechanism maintains user stability while delivering realistic cycling feedback

Function Achieved in This Case
The flexible trainer stand provides realistic somatosensory feedback, adjustable force, and extended equipment lifespan, enhancing indoor cycling experience and comfort while supporting various training equipment.
Implementation Method 1
the elastic devices are symmetrically arranged at two ends of the beam. Each of the elastic devices includes one end fixedly connected with the beam, and the other end fixedly connected with the bottom end of the flat plate
Implementation Method 2
The first guide portion is slidably connected with the second guide portion

AI summary
A flexible trainer stand for indoor cycling includes a bracket, a flat plate, a first guide portion, a second guide portion, and elastic devices. The first guide portion and the second guide portion can slide relative to each other, which is configured for simulating forward and backward movement of a bike generated when a user accelerates and sprints. The first guide portion and the second guide portion can be inclined under an action of the elastic device, which is configured for simulating left and right inclination of the bike generated when the user is cycling and exerting force. A lifting device is arranged on the flat plate, which is configured for simulating position changes of the bike in a vertical direction when a slope changes. Somatosensory feedback of the user during outdoor cycling is truly simulated, and a feedback force can be adjusted.
