Tilting Bed Cart for Restricted Space Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing material movement systems, such as hand trucks and dollys, are ineffective in navigating around obstacles and through areas with limited space, particularly in construction sites where physical restrictions like wall heights and doorway dimensions hinder the movement of large items, often requiring labor-intensive and dangerous manual carrying up stairs.
Innovation Solution
A tilting bed cart/truck with a lifting mechanism and adjustable framework that allows objects to be tilted and moved in a reduced space, maintaining load stability and reducing the area required for movement by adjusting its length and orientation, enabling passage through narrow spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If objects are moved using traditional hand trucks or dollys, then the movement is simple in open spaces, but the objects cannot be moved around obstacles or through limited spaces such as narrow hallways and elevators
Solution Approach 1:
The cart employs a tilting bed mechanism that can dynamically adjust its orientation angle. The bed tilts upward to reduce the horizontal footprint of carried objects, enabling passage through narrow doorways and elevators, then returns to horizontal for stable transport on flat surfaces. This dynamic adaptation resolves the contradiction between maneuverability in restricted spaces and operational simplicity.
Solution Approach 2:
The invention introduces a vertical dimension to the transport problem by tilting the bed upward. Instead of solely moving objects horizontally through narrow spaces, the system rotates objects into a tilted configuration, effectively using the vertical dimension to reduce the horizontal space requirement and enable passage through restricted areas.
2Area of stationary object
If objects are tilted upward to reduce movement space, then the area required to move objects is reduced, but the stability of the load may be compromised
Solution Approach 1:
The cart maintains load stability during tilting through a coordinated dynamic system: the bed tilts upward to reduce footprint while the base simultaneously contracts (base members move closer together). This coordinated motion maintains the load center between the wheels throughout the tilting process, preventing instability. The system dynamically adapts its configuration to preserve stability while achieving compact movement.
Solution Approach 2:
The invention changes multiple parameters simultaneously during tilting: the bed angle increases to reduce horizontal space, while the base width decreases (base members move closer) to maintain stability. By coordinating these parameter changes, the system achieves compact movement without compromising load stability.
3Stability of the object's composition
If the base members are moved closer together to maintain load center during tilting, then the stability is maintained, but the length layout of the cart changes
Solution Approach 1:
The cart employs dynamic adjustment of base member positions during operation. The sliding mechanism allows base members to move closer together during tilting to maintain stability, then move apart when returning to horizontal configuration. This dynamic adaptation enables the cart to change its effective length based on operational requirements, maintaining stability when needed while preserving maneuverability when returning to transport mode.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the stable and efficient movement of large objects through restricted areas by reducing the space needed, allowing objects to be transported around obstacles and up stairs without manual carrying, thus reducing labor and safety risks.
Implementation Method 1
The lifting cylinder may be configured so that it can be mounted to one base member and mounted to the holding framework so that it can move the holding framework in an upward and backward direction

AI summary
A method and system are disclosed for moving material past an obstacle and/or for moving materials in areas of limited space. A user can move so that the area and space required to move an object is reduced. A user can utilize the system and method to load an object and then tilt the object to be moved so that the area needed to move an object is reduced. After the object has been tilted, a user can move the object in locations characterized by various physical restrictions such as limited height, width, and length dimensions that do not ordinarily allow for movement of larger sized objects.
