Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If motor-driven slope adjustment mechanism is used, then slope adjustment function is achieved, but cost and device complexity increase
Solution Approach 1:
The patent replaces the motor-driven mechanical system with a pure mechanical folding block system. The folding block with rotating connection part and supporting part eliminates the need for motors, circuits, and complex control systems while achieving the same slope adjustment function through simple mechanical leverage and geometric transformation.
Solution Approach 2:
The patent uses simple, inexpensive mechanical components such as folding blocks, rotating connection parts, and supporting parts instead of expensive motor assemblies. These simple mechanical parts are easier to manufacture, replace, and maintain, reducing both initial cost and long-term maintenance expenses.
2Adaptability or versatility
If motor-driven slope adjustment mechanism is used, then slope adjustment function is achieved, but maintenance and repair costs increase
Solution Approach 1:
By replacing the motor-driven system with a pure mechanical folding block system, the patent eliminates motors, circuit boards, wires, and electronic controls that require specialized maintenance. The mechanical folding blocks with rotating connections are simpler, more durable, and easier to repair with basic tools and knowledge.
3Device complexity
If manual folding block mechanism is used, then device complexity and cost are reduced, but slope adjustment range may be limited
Solution Approach 1:
The patent employs a dynamic folding block mechanism where the supporting part can rotate relative to the supporting frame through a rotating connection part. This dynamic rotation allows the treadmill to achieve multiple slope positions (including maximum and minimum slopes) as the folding block moves between different angular positions, providing adequate adjustment range despite the simple mechanical structure.
