Telescopic Ladder With Non-Circular Posts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ladder attachment systems for water vessels lack a convenient and secure mechanism to retract and deploy ladders easily, particularly in a vertically raised orientation, with a need for a telescopic central member and locking system to facilitate easy storage and operation.
Innovation Solution
A ladder attachment system featuring a base member with a central channel and lock member, a pivot mount, and telescopically extending ladder sections with non-circular central posts to prevent rotation, allowing for easy retraction and extension while maintaining stability and secure locking in both operational and stored orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a ladder attachment system is designed to be retractable and storable, then the ease of operation is improved, but the device complexity increases due to the need for locking mechanisms and telescopic components
Solution Approach 1:
The ladder is divided into multiple telescopic sections that can extend and retract independently, allowing the ladder to be stored in a compact configuration and deployed when needed. The base member is segmented with multiple channels to accommodate different positions of the telescopic sections.
Solution Approach 2:
The telescopic ladder sections are nested within each other, with inner sections fitting inside outer sections when retracted. This nesting arrangement allows the ladder to occupy minimal space when stored while maintaining full extendability for use.
Solution Approach 3:
A lock member acts as an intermediary between the base member and telescopic sections, providing a locking mechanism that secures the ladder in desired positions. The lock member engages with channels in the base member to maintain stable positioning during use.
2Ease of operation
If the ladder sections are made telescopically extending, then the ease of operation is improved, but the stability may worsen due to potential rotation between sections
Solution Approach 1:
The central posts of the ladder sections have non-circular cross-sections (rectangular or oval shapes) rather than circular cross-sections. This asymmetric geometry prevents rotation between telescopic sections while maintaining smooth axial extension and retraction, as the asymmetric shapes cannot rotate relative to each other along the telescopic axis.
3Ease of operation
If the ladder is designed to fit within a defined plane for concealed storage, then the ease of operation is improved, but the device complexity increases due to precise geometric constraints
Solution Approach 1:
The ladder system utilizes three-dimensional spatial arrangement where telescopic sections extend and retract along a vertical axis while the base member provides horizontal positioning. This multi-dimensional configuration allows the ladder to achieve compact concealed storage within a defined plane while maintaining full operational capability when deployed.

AI summary
A ladder attachment having a base member slideably attached to lock member, a pivot mount pivotally attached to the lock member and a surface defining a lock port which is optimally configured to be orientated to slide upon the lock member when in a stored orientation such that when the base member and pivot mount is slideably repositioned with respect to the lock member, a ladder assembly which is attached to the pivot mount is in a stored orientation. The ladder assembly has an extended and retracted orientation.
