Triple plank platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescoping work platforms are limited in their collapsibility, typically folding only to half their maximum length, resulting in increased weight and difficulty in transportation and handling, as well as weight capacity constraints due to support limitations.
Innovation Solution
A telescoping work platform design featuring two outer sections with prongs that slide within channels of a midsection, allowing the platform to extend to approximately three times its collapsed length, with reinforcing plates and end caps for strength and ease of use, and a grooved surface for traction, made from lightweight materials like aluminum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the platform is made collapsible to half its maximum length, then portability and storage are improved, but the weight increases and handling becomes more difficult
Solution Approach 1:
The outer sections are nested within the midsection through telescoping prongs that slide within channels, allowing the platform to collapse to approximately one third of its maximum length. This nesting arrangement reduces the collapsed volume more effectively than conventional half-collapse designs while minimizing the additional weight that would result from the telescoping mechanism.
2Volume of moving object
If the platform is made collapsible to half its maximum length, then portability is improved, but difficulty in transportation and handling increases
Solution Approach 1:
The telescoping nested structure allows the platform to collapse to approximately one third of its maximum length, significantly reducing the volume for transport and storage. The alternating prong and channel design provides smooth sliding action that facilitates easy expansion and collapse operations, improving handling ease compared to conventional designs.
3Volume of moving object
If the platform uses conventional telescoping arrangements, then collapsibility is achieved, but weight capacity is limited due to support limitations
Solution Approach 1:
The nested telescoping structure with outer sections containing prongs that slide within channels of the midsection provides a stable load-bearing configuration. The alternating prong and channel arrangement distributes loads effectively across multiple contact points, maintaining weight capacity while achieving collapse to one third of maximum length.
Solution Approach 2:
The platform incorporates localized reinforcement at critical areas where the outer sections interface with the midsection. The prongs and channels are designed with specific geometric features that concentrate strength where needed during telescoping operations, ensuring adequate weight capacity is maintained despite the collapsed configuration.

AI summary
A telescoping work platform utilizing three planks that are slidable to each other allows for a longer maximum length for use while providing for a shorter collapsed length for storage all while providing necessary structural support.
