Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ladders lack versatility and safety features for use on irregular surfaces and do not provide optimal storage solutions for tools and products.
Innovation Solution
A stepladder design featuring a lower base with a curved finish for stable placement on any surface, an upper base with a 'V' shaped seal for versatile positioning, and a safety clip for secure closure, enhancing portability and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional ladder base design is used, then the ladder structure is simple, but the ladder cannot safely place on irregular surfaces
Solution Approach 1:
The lower base incorporates a curved finish that allows the ladder to adapt to and place safely on irregular surfaces. The curvature enables the base to conform to various surface geometries, improving reliability without requiring complex adjustable mechanisms.
Solution Approach 2:
The upper base features a geometric finish with a 'V' shaped seal at one edge, providing localized adaptation to irregular surfaces. This targeted geometric feature allows safe placement on corners and uneven surfaces while maintaining simplicity in the overall base structure.
2Adaptability or versatility
If a traditional ladder design is used, then the ladder structure is simple, but there is no storage space for tools and products
Solution Approach 1:
The upper base is designed with multiple functions: it provides a geometric finish for surface adaptation, includes a 'V' shaped seal for corner positioning, and incorporates storage space for tools and products. This multi-functionality increases versatility while adding minimal structural complexity.
3Volume of moving object
If the ladder is designed for compact storage, then the storage space is optimized, but the ladder may not provide sufficient stability when open
Solution Approach 1:
The ladder incorporates a hinge-type connecting element that allows dynamic transformation between closed and open positions. The hinge enables compact folding for storage while maintaining structural integrity and stability when deployed, balancing volume efficiency with operational stability.
4Reliability
If a safety clip is added to secure the ladder in closed position, then the safety and portability are improved, but the device complexity increases
Solution Approach 1:
The safety clip is designed as a self-latching mechanism that automatically secures the ladder in the closed position without requiring additional actuators or complex control systems. The clip engages with the hinge structure to provide reliable closure while adding minimal complexity.

AI summary
Stepladder with lower base, upper base and safety clip, which is composed of two main bodies that we will call body of rungs and complementary body, with long and short lower bases, with curved shape and rough surface, and with an upper base, which in one of its edges has a “V” type break with a safety clip, with a hinge type joint element, which allows us to use the ladder in open use position and closed use position and which also has an additional support, and also has long reinforcement elements and short reinforcement elements that together allow us to have a solid and robust ladder.
