Modular Lift Platform Segmentation for Versatility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial lifting platforms require a large inventory of fully assembled units and parts to accommodate various types and configurations, limiting flexibility and increasing costs due to their fixed designs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If lifts are designed with fixed configurations to achieve basic purposes, then structural simplicity is maintained, but adaptability and versatility are reduced
Solution Approach 1:
The lift system is divided into modular components including interchangeable frame members, attachable platform modules, and separable powering units. This segmentation allows customers to assemble different lift configurations from standardized parts, achieving versatility without requiring completely different designs for each application type.
Solution Approach 2:
The patent creates a universal lift platform that can serve multiple functions through modular attachments. The same base lift can be configured for stationary operation, mobile operation with wheels, tilting operations, or rotation operations by attaching different modules, eliminating the need for separate specialized lifts for each function.
2Adaptability or versatility
If a large inventory of fully assembled lifts and parts is maintained to accommodate various types, then customer demand for diverse lift types is met, but inventory costs and complexity increase
Solution Approach 1:
Instead of maintaining inventory of complete assembled lifts for different applications, the system segments lifts into standardized modular components. Customers assemble their specific lift types from these universal modules, dramatically reducing the variety of parts that need to be inventoried while still meeting diverse customer requirements.
Solution Approach 2:
A single universal set of modular components can assemble into multiple different lift types (stationary, mobile, tilting, rotating). This universality eliminates the need to maintain separate inventories for each lift type, as all configurations use the same standardized parts.
3Strength
If the lift structure is made stronger to handle high lifting capacity, then load-bearing capability is improved, but component size and weight increase
Solution Approach 1:
Rather than making the entire lift structure uniformly heavy and strong, the patent applies strength and material mass only at critical locations where loads are transmitted. The modular design allows optimization of each component's strength to its minimum necessary level, reducing overall weight while maintaining required lifting capacity.
Solution Approach 2:
The segmented modular architecture allows each component to be optimized independently for its specific structural role. Load-bearing elements can be sized for their specific functions rather than being oversized to handle maximum capacity throughout the entire structure, reducing unnecessary weight.
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 assembly of a wide variety of lifts with reduced inventory costs by allowing for reconfiguration of lifts, maximizing structural strength while minimizing component size and weight, and providing flexibility to meet diverse customer demands.
Implementation Method 1
The powering unit or force generating subassembly in some of the illustrated embodiments is achieved by a plurality of inflatable chamber's (which resemble tires, air bags or bellows) that act directly between the upper and lower frames
