Solution Overview
Problem
Existing solutions lack an efficient and user-friendly method for moving loads from one height to another, particularly from a truck cargo bed to a workroom or garage, requiring multiple people and complex equipment.
Innovation Solution
A device with a platform, guide members, a support member, and a lift assembly with adjustable leg assemblies powered by a hydraulic system, allowing a single person to easily transfer loads between heights using a controller to extend and retract the legs and move the platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing solutions are used to move loads from one height to another, then the task can be completed, but it requires multiple people and complex equipment
Solution Approach 1:
The device is divided into distinct functional modules: a platform for holding the load, guide members for directional movement, a support member with roller assemblies for smooth translation, and an adjustable leg assembly for height adaptation. This segmentation allows each component to perform its specific function efficiently, reducing overall system complexity while maintaining ease of operation.
Solution Approach 2:
The leg assembly incorporates adjustable height capability, allowing the device to adapt dynamically to different height requirements (e.g., from truck cargo bed to workroom level). This dynamic adjustability eliminates the need for multiple fixed-height devices, simplifying operation across various scenarios.
2Productivity
If existing solutions are used to move loads from one height to another, then the task can be completed, but it requires multiple people
Solution Approach 1:
The device replaces manual human effort with a mechanical assistance system. The roller assemblies reduce friction between the support member and guide members, enabling smooth movement with minimal force. This mechanical substitution allows a single person to perform tasks that previously required multiple people, significantly improving productivity while maintaining ease of operation.
3Adaptability or versatility
If the support member is extended beyond the platform length, then the range of motion is increased, but the stability may be reduced
Solution Approach 1:
The leg assembly's adjustable height feature allows the device to maintain optimal stability characteristics for each operational position. When extended for greater range of motion, the legs can be adjusted to provide adequate support length, dynamically balancing stability and versatility.
Solution Approach 2:
The roller assemblies act as intermediaries between the support member and guide members, distributing loads and reducing friction. This intermediary mechanism allows the support member to extend beyond platform length while maintaining stability through reduced friction and improved load distribution.

AI summary
The embodiments of the invention are directed to a device and method for moving a load from a first height at a first location to a second height at a second location. The device includes a platform having a top surface and a bottom surface, and opposed guide members extending from the bottom surface of the platform and oriented along and parallel to the length of the platform. The device further includes a support member slidably engaged with the guide members, the support member capable of extending beyond the length of the platform or retracting beneath the platform. The device further includes a lift assembly having a frame and a controller. The frame is pivotably secured to the lower surface of the support member. The frame has a pair of parallel, opposed, leg assemblies where the height of the leg assembly is adjustable, and the controller controls the height of the leg assemblies.
