Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing ramp systems are used, then basic access is provided, but they are not modular and adaptable to varying structures
Solution Approach 1:
The ramp system is divided into multiple modular components including a first component with horizontal and vertical portions, a second component with protrusion and channel, and interchangeable fastening mechanisms. This segmentation allows the system to be configured for different structures while maintaining manageable complexity through standardized interfaces.
Solution Approach 2:
The modular components are designed with universal features such as the hook that can engage with various lip configurations, the interchangeable fastening mechanisms (screws, clips, adhesives), and the adjustable angle capability. This universality enables a single component set to adapt to multiple different structures including buildings, storage containers, and vehicles.
2Adaptability or versatility
If fixed angle ramps are used, then simple construction is achieved, but variable angle adjustment and secure attachment are limited
Solution Approach 1:
The ramp system transitions from fixed angle to dynamically adjustable angle through the interchangeable fastening mechanisms. The channel and protrusion allow the ramp surface to be positioned at multiple angles, while the various fastening options (screws, clips, adhesives) enable secure attachment at each desired angle, making the system adaptable to different terrain and structure configurations.
3Adaptability or versatility
If non-modular ramp systems are used, then manufacturing is simpler, but adaptability to different structures is reduced
Solution Approach 1:
The ramp is segmented into standardized components (first component with horizontal/vertical portions, second component with channel/protrusion, interchangeable fasteners) that can be manufactured independently using standard processes. This segmentation maintains manufacturing simplicity while enabling assembly adaptability to different structures including buildings, storage containers, and vehicles.
Solution Approach 2:
The modular design allows for parameter changes in configuration (angle, position, attachment method) without changing the fundamental component geometry. The standardized interfaces and interchangeable fastening mechanisms enable the same components to be manufactured once and then configured in multiple ways for different applications.

AI summary
A ramp system is disclosed which may include first and second components. The first component may include horizontal and vertical portions, and a hook. The horizontal portion may be supported by a lip of a structure, and may have a width equivalent to a length of the lip. The vertical portion may be coupled with, and hang downward from, the horizontal portion, and may have the same width as the horizontal portion. The hook may be coupled with the vertical portion, and may have the same width as the horizontal portion. The second component may include a protrusion and channel. The protrusion may have a width equal or less than the width of the horizontal portion, and be supported by the hook. The channel may be coupled with the protrusion, and have the same width. The channel may receive a planar component which forms a sloped surface of a ramp.
