Dual-Function Fenders for Generator Set Fork Pockets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile generating sets face challenges in providing comprehensive protection against shocks and corrosion, particularly in fork pockets, during handling, transport, and storage, which leads to deformation and deterioration of the chassis.
Innovation Solution
The integration of molded rubber or plastic protective elements around the fork openings, secured to a metal reinforcing plate, provides double protection against shocks and corrosion, while also allowing for easy maintenance and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional bumpers are placed on the frame to protect against shocks, then general shock protection is improved, but fork pocket edges remain vulnerable to deformation and corrosion
Solution Approach 1:
The protective element incorporates a specific local structure where the lower portion extends beyond the frame surface to form a protective lip around the fork pocket opening. This localized extension provides targeted protection for the vulnerable edges of the fork pockets, while the upper portion maintains general shock protection functionality.
2Object-affected harmful factors
If multiple separate protective elements are used for frame protection and fork pocket protection, then comprehensive protection is achieved, but device complexity and cost increase
Solution Approach 1:
The invention merges the general frame bumper function and the specific fork pocket edge protection function into a single integrated protective element. This unified component is mounted on the frame and simultaneously provides both protection functions, thereby reducing the total number of parts while achieving comprehensive protection.
Solution Approach 2:
The protective element is designed with multi-functionality, serving both as a general shock-absorbing bumper for the frame and as a specific protective barrier for the fork pocket edges. The lower extension portion specifically addresses fork pocket protection while the entire structure maintains general bumper functionality.
3Strength
If protective elements are made from rigid materials, then structural strength is improved, but resistance to shock and impact damage decreases
Solution Approach 1:
The protective element is constructed as a composite structure combining a rigid support framework with a flexible protective covering. The rigid framework provides structural strength and mounting stability, while the flexible material layer absorbs impact energy and protects against shock damage, creating a balanced composite protective system.

AI summary
The invention relates to a generator set including a frame (11) on which in particular a motor and an alternator are mounted, protected by a housing (12), said frame (11) having at least two openings (111, 112) allowing passage of the forks of a forklift truck. Such a generator set includes protective elements (14) mounted surrounding said openings, each providing dual protection: on the one hand, of the outer surface of said frame, against impacts due particularly to handling, transportation and/or storage, by extending beyond the surface of said frame in the neighborhood of said fender; and on the other hand against impacts due to the insertion of said forks, by surrounding said edges.
