Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a motor-driven slope adjustment mechanism is used, then the slope adjustment function is achieved, but the manufacturing cost increases
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 achieves slope adjustment through manual mechanical operation, eliminating the need for motors and electrical components, thereby reducing manufacturing cost while maintaining the slope adjustment function.
Solution Approach 2:
The patent extracts and removes the motor and electrical components from the slope adjustment mechanism, retaining only the essential mechanical elements (folding block, rotating connection part, supporting part). This extraction eliminates the costly electrical subsystem while preserving the core functionality of slope adjustment.
2Adaptability or versatility
If a motor-driven slope adjustment mechanism is used, then the slope adjustment function is achieved, but the device complexity increases
Solution Approach 1:
The patent substitutes the complex motor-driven system with a simple mechanical folding block system. By replacing electrical motors, control circuits, and associated mechanical transmission components with a straightforward mechanical folding structure, the device complexity is significantly reduced while the slope adjustment function remains intact.
Solution Approach 2:
The patent removes the electrical circuit structures and motor components from the system, leaving only the essential mechanical elements. This extraction of complex electrical and mechanical subsystems directly reduces the overall device complexity while maintaining the core slope adjustment capability.
3Adaptability or versatility
If a motor-driven slope adjustment mechanism is used, then the slope adjustment function is achieved, but the maintenance and repair costs increase
Solution Approach 1:
The patent replaces the motor-driven system with a simple mechanical folding block system. Mechanical components such as the folding block, rotating connection part, and supporting part are easier to maintain and repair compared to electrical motors and circuits. The simplified mechanical structure reduces maintenance requirements and lowers repair costs.
Solution Approach 2:
The patent extracts and removes the electrical components (motors, circuits, controllers) that require specialized maintenance and repair. By eliminating these complex electrical subsystems, the remaining mechanical system becomes simpler to maintain and repair, directly reducing maintenance and repair costs.
4Adaptability or versatility
If a motor-driven slope adjustment mechanism is used, then the slope adjustment function is achieved, but the failure rate increases
Solution Approach 1:
The patent substitutes the motor-driven system with a simple mechanical folding block system. Mechanical components have fewer failure points compared to electrical motors and circuits. The folding block with rotating connection part and supporting part creates a robust mechanical system with higher reliability and lower failure rate while maintaining the slope adjustment function.
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
The manual slope adjustment mechanism reduces manufacturing and maintenance costs, simplifies the structure, and lowers the failure rate compared to electrical lifting mechanisms, while providing stable and adjustable slope settings.
Implementation Method 1
the folding block including a rotating connection part rotatably connected to the supporting frame
Implementation Method 2
the folding block is provided with a first limiting part and a second limiting part, the first limiting part being configured to limit a first endpoint in the rotating process of the folding block, and the second limiting part being configured to limit a second endpoint in the rotating process of the folding block
Implementation Method 3
the first limiting part is a top of the supporting part, and through press fit between the top of the supporting part and the bottom of the running frame, limits the folding block to continue to rotate in a rotating direction
Implementation Method 4
a roller is arranged at a grounding end of the supporting part
Implementation Method 5
the supporting part is provided with a braking surface tangent to an arc-shaped end face of the supporting frame, and the braking surface is in interference fit with the arc-shaped end face, so that when the folding block rotates around the rotating shaft, a braking force is formed through a friction force between the braking surface and the arc-shaped end face
