Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing modular ramp systems use multiple large parts and fasteners to achieve adjustability, then the ramp can accommodate different elevations, but the number of parts increases and assembly time exceeds seven hours
Solution Approach 1:
The patent combines multiple separate components (locating pins, support pins, fasteners) into integrated connector elements that perform multiple functions simultaneously. The connector includes both locating and support features in a single component, reducing the total part count while maintaining the ability to accommodate different elevations and configurations.
Solution Approach 2:
The ramp system uses universal connectors that can accommodate various module configurations and elevation differences. The same connector design works for different ramp sections, platforms, and configurations, eliminating the need for multiple specialized parts and reducing overall system complexity.
2Adaptability or versatility
If existing modular ramp systems are custom-configured at a factory based on site evaluation, then the ramp can be precisely fitted to specific needs, but the time required for configuration, fabrication, and delivery increases
Solution Approach 1:
The ramp system is divided into standardized modular sections that can be independently manufactured and then assembled on-site. This segmentation allows for pre-fabrication of individual modules while maintaining the ability to create custom configurations through simple assembly, significantly reducing both factory lead time and on-site assembly time.
Solution Approach 2:
The modular components are pre-configured with integrated connectors and locating features during manufacturing, so that no complex field adjustments or custom fabrication is needed during installation. The preliminary preparation of standardized interfaces enables rapid assembly without requiring skilled labor or specialized tools.
3Adaptability or versatility
If existing modular ramp systems include greater than one-hundred large parts and greater than one-thousand fasteners, then the system can be highly configurable, but the cost in labor of assembly becomes great and commercial availability is limited
Solution Approach 1:
The patent merges multiple fastening and locating functions into single integrated connector components. Instead of using separate fasteners, locating pins, and alignment features, the design consolidates these into unified elements that reduce the total component count from over 100 parts to a manageable number, directly reducing assembly labor costs.
Solution Approach 2:
Universal connector designs are employed that can serve multiple configuration needs across different ramp sections. A single connector type can accommodate various module arrangements, eliminating the need for multiple specialized fastener types and reducing both inventory complexity and assembly time.
4Stability of the object's composition
If existing modular ramp systems are designed as permanent or semi-permanent structures, then the ramp provides stable access, but the system becomes difficult to deliver and requires specialized transportation
Solution Approach 1:
The ramp system is segmented into modular sections that can be compactly packaged for standard vehicle delivery. Each module is sized and weighted for easy handling, allowing the complete system to be transported in conventional vehicles rather than requiring specialized heavy equipment transportation.
Solution Approach 2:
The connector design incorporates dynamic features that allow for quick assembly and disassembly while maintaining structural stability when assembled. The system transitions from a compact transport state to a stable installed state through simple connector engagement, providing both deliverability and structural integrity.

AI summary
An adjustable, modular handicap-access-ramp system enables transport of wheelchairs and temporarily or permanently physically handicapped individuals and no-step access thereof into and out of a structure. The system comprises a plurality of core modules and at least one additional module adapted to be combined with each other and the core modules to configure a customized ramp. At least one combined locating and support pin is adapted to connect to each other those of the core and additional modules disposed adjacent to each other. At least one substantially infinitely adjustable column assembly allows movement of predetermined core and additional modules up or down and to a desired angle. At least one connector allows attachment to each other of adjacent core and additional modules that require a change in grade with respect to each other.
