Engine Generator Nestable Handle and Mount for Vertical Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engine generators are not easily stackable, requiring additional components like plywood or stacking kits, which complicates the stacking process and increases costs due to the need for specific stacking members for each design.
Innovation Solution
Incorporating a handle assembly at the top and a mount arrangement at the bottom of the engine generator, allowing the handle assembly and mount arrangement to be nestable, enabling efficient vertical stacking without the need for additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If engine generators are designed with traditional handles and mounts, then they can be carried and supported, but they cannot be easily stacked vertically
Solution Approach 1:
The handle assembly at the top of the upper generator and the mount arrangement at the bottom of the lower generator are designed with complementary nestable shapes, allowing the same structural components to serve both their original functions (carrying and supporting) and the additional function of enabling vertical stacking without requiring separate stacking accessories
Solution Approach 2:
The handle assembly and mount arrangement are shaped to fit within each other when generators are stacked vertically, with the handle assembly nesting into the mount arrangement of the generator below, creating a compact stacked configuration that eliminates the need for additional stacking members
2Adaptability or versatility
If stacking kits with separate members are used to stack engine generators, then vertical stacking is enabled, but costs increase and stacking work becomes troublesome
Solution Approach 1:
The handle and mount structures are designed to perform their original functions while simultaneously serving as stacking interfaces, eliminating the need for separate stacking kit members and reducing manufacturing costs by avoiding additional components
Solution Approach 2:
The generators are designed with built-in nestable handle and mount structures that enable self-stacking capability, allowing users to stack generators without requiring external stacking accessories or complex assembly procedures
3Adaptability or versatility
If plywood sheets are used to stack engine generators vertically, then stacking is possible, but the process becomes complicated and requires additional materials
Solution Approach 1:
The handle assembly and mount arrangement are shaped to fit within each other, allowing generators to be stacked directly by nesting the handle of the upper generator into the mount of the lower generator, eliminating the need for plywood sheets or other intermediary materials
Solution Approach 2:
The nestable handle and mount structures serve as built-in intermediaries that directly enable vertical stacking, replacing the need for external intermediary materials like plywood sheets and simplifying the stacking operation to a direct fit-between-process

AI summary
Mounts can be provided at the four corners of a bottom portion of an engine generator. Projections for mounting handles can be provided at a top portion of the engine generator in vertical alignment above the mounts. The bottom face of each mount can be formed with a fitting groove having an open end. Fitting the projections in the fitting grooves allows stacking plural engine generators. The mount can be constituted with a bottom portion, a side portion, and a reinforcing metal fitting. The projections can be disposed on a front frame and a rear frame, respectively, each formed in one body. The mounts can also be attached to the front frame and the rear frame.
