Work Platform One-Handed Lifting Handle and Hinge Tab
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work platforms are cumbersome to move when unfolded, often requiring users to put down tools and use both hands to lift them, risking tipping and entanglement with objects, and lack a secure mechanism to prevent leg collapse under load.
Innovation Solution
A work platform design featuring a handle with oval slots and inserts, allowing one-handed lifting without tipping, and a hinge bracket with tabs that provide a firm stop for the legs when unfolded, ensuring stability and rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the work platform is designed without a dedicated handle, then the structure remains simple, but the user cannot conveniently lift the platform with one hand without risking tipping
Solution Approach 1:
The handle is integrated into the platform structure by forming slots directly in the platform surface, combining the lifting function with the platform body rather than adding a separate handle component. This reduces overall structural complexity while providing convenient one-handed lifting capability.
Solution Approach 2:
The handle functionality is created through slots (a two-dimensional feature) rather than a three-dimensional protruding handle, allowing the lifting function to be embedded in the platform surface without adding vertical complexity or interfering with the platform's folded configuration.
2Ease of operation
If the handle is positioned away from the center of gravity, then the structure is simpler to manufacture, but the platform tips when lifted
Solution Approach 1:
The slots are positioned to align with the platform's center of gravity, creating a balanced lifting point where the platform's weight is evenly distributed. This positioning ensures stable lifting without tipping while maintaining manufacturing simplicity through straightforward slot placement in the platform's central region.
3Reliability
If the legs are unfolded without a firm stop mechanism, then the structure remains simple, but the legs may collapse under load reducing reliability
Solution Approach 1:
The hinge bracket's tab structure automatically engages with the leg to provide a firm stop when unfolded, without requiring external locking mechanisms or additional components. The geometry of the tab and leg interface self-regulates to prevent over-extension and collapse under load.
Solution Approach 2:
The tab on the hinge bracket features a curved or rounded surface that complements the leg's contact point, creating a natural stopping position through geometric constraint rather than mechanical locking. This curved interface provides reliable support while maintaining structural simplicity.

AI summary
An apparatus includes a platform having a first end and a second end and a handle. The apparatus includes a first leg assembly rotatably attached to the platform in proximity to the first end. The apparatus includes a second leg assembly attentively attached to the platform in proximity to the second end. When the first and second leg assemblies are essentially perpendicular to the platform, the apparatus is in a use state and the user is able to stand on the platform and be supported by the first and second leg assemblies. When the apparatus is in the use state, the user is able to pick up the apparatus by the handle with only one of the hands without tipping the apparatus. A method for a user with hands to stand on an apparatus. A work platform having legs which are coplanar with the platform when the legs are in a closed position. The work platform having a hinge bracket with a tab against which a leg contacts and is stopped when the leg is in an open position.
