Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal materials are used to compose the vehicle ramp, then the strength and load-bearing capacity are improved, but the weight increases and occupies large space
Solution Approach 1:
The patent changes the material parameter from metal to plastic, fundamentally altering the density and weight characteristics while maintaining structural integrity through optimized geometric design. The plastic material provides sufficient strength for vehicle support while dramatically reducing weight and storage space requirements.
Solution Approach 2:
The patent incorporates arc-shaped grooves and arc-shaped depressions into the ramp structure. These curved features increase structural rigidity and load-bearing capacity while using less material, thereby reducing weight. The arc-shaped design also facilitates nesting and compact storage when not in use.
2Strength
If metal materials are used to compose the vehicle ramp, then the load-bearing capacity is improved, but the ease of movement deteriorates
Solution Approach 1:
Changing from metal to plastic material fundamentally alters the weight parameter, making the ramp portable and easy to move while maintaining adequate load-bearing capacity through optimized structural geometry and material distribution.
Solution Approach 2:
The ramp is designed as a modular structure with distinct components including the base frame, sloping plate, and stacking features. This segmentation allows for easier handling, assembly, and storage while maintaining overall structural strength.
3Ease of operation
If the ramp structure is simplified for easy movement, then the ease of operation is improved, but the strength deteriorates
Solution Approach 1:
Arc-shaped grooves and arc-shaped depressions are integrated into the ramp structure to enhance rigidity and load-bearing capacity. These curved features act as structural reinforcements that prevent deformation under vehicle weight while maintaining the lightweight plastic construction for easy portability.
Solution Approach 2:
The patent utilizes plastic material with optimized structural design, creating a composite effect where the material properties and geometric configuration work together to achieve both high strength-to-weight ratio and portability.
4Ease of operation
If multiple ramps are stored separately, then the accessibility is improved, but the storage space occupation increases
Solution Approach 1:
The ramp features a hollow bottom structure that enables one ramp to be nested inside another when not in use. This nesting capability significantly reduces storage space requirements while keeping multiple ramps readily accessible when needed.
Solution Approach 2:
Multiple ramps are combined into a compact stacked configuration through the hollow bottom design, allowing them to occupy minimal storage space while remaining individually accessible for use.

AI summary
The invention relates to the technical field of vehicle maintenance equipment, in particular, to a stacked vehicle ramp. The vehicle ramp includes a base frame. One end of the base frame is fixedly connected with a sloping plate, and both sides of the base frame are fixedly provided with a side plate. The other end of the base frame is fixedly connected with a rear plate, and a higher end of the sloping plate is fixedly connected with a top plate that is horizontally arranged. The sloping plate, the top plate and the rear plate are all fixedly connected between the two side plates, and one end of the top plate away from the sloping plate is fixedly connected to the rear plate. A first left groove and a first right groove are provided on the sloping plate, and the top plate is provided with a second left groove and a second right groove. The first left groove and the second left groove are both formed with left arc-shaped depressions, and both positions of the first right groove and the second right groove corresponding to the left arc-shaped depressions are formed with right arc-shaped depressions. The two side plates are provided with a plurality of arc-shaped grooves. The application has the effect that the support strength of the vehicle ramp can be greatly enhanced, and the vehicle ramp can also support the vehicle even by using lightweight materials.
