Adjustable Work Platform With Telescoping Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible work platforms are fixed in height and width, leading to unnecessary fatigue and instability issues for users who need to stretch or bend to reach work areas, and they often compromise on portability and storage due to rigid configurations.
Innovation Solution
A collapsible work platform with adjustable folding leg frames that allow for one-handed height and width adjustments, enabling easy transformation between use and storage configurations, and featuring telescoping legs and laterally extendable feet with lock mechanisms for stability and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the work platform is made fixed in height and width to provide stability, then the platform stability is improved, but the user convenience deteriorates as users must stretch or bend to reach work areas
Solution Approach 1:
The patent applies the dynamics principle by making the platform adjustable in both height and width through telescoping leg frames and laterally extendable feet with lock mechanisms. This allows the platform to transition from a fixed configuration to an adjustable one, enabling users to optimize the platform dimensions for different work scenarios while maintaining stability when locked in position.
2Stability of the object's composition
If the work platform width is increased to provide a more stable and comfortable surface, then the platform stability is improved, but the portability and storage capability deteriorate
Solution Approach 1:
The patent implements dynamics by providing laterally extendable feet that can be adjusted between extended and retracted positions. When extended, they provide a wider platform for stability; when retracted, they minimize the platform footprint for compact storage and improved portability.
Solution Approach 2:
The patent applies segmentation by dividing the leg frames into telescoping sections and the feet into laterally extendable components. This modular segmentation allows each element to be adjusted independently, enabling the platform to optimize its width for stability during use while compacting for storage.
3Ease of operation
If the work platform is designed for easy adjustment between configurations, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent applies self-service through the use of gravity-assisted telescoping legs and spring-loaded lock mechanisms that automatically engage when the leg frames are extended. This reduces the need for complex manual adjustment mechanisms while maintaining ease of operation.
Solution Approach 2:
The patent extracts the locking function from complex mechanical systems and implements it through simple spring-loaded mechanisms that engage with the telescoping leg frames. This simplifies the overall device complexity while maintaining ease of adjustment.

AI summary
A work platform configured to be adjustable in both height and width, while enabling ease in transformation between an open, use configuration in a closed, storage configuration. The work platform having a platform and a pair of leg frames pivotably coupled to opposite ends of the platform, each of the pair of leg frames including a first leg and a second leg, each of which includes a first member pivotably coupled to the platform, and a second member shiftable relative to the first member, an intermediate rung operably coupled to respective distal ends of the first members and including a length extension lock mechanism configured to inhibit shifting of the second members relative to the first members, and a base rung member including a crossmember operably coupled to the respective distal ends of the second members.
