Bump Stopper Rod for Engine Position Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position regulating apparatuses for engine operating machines require significant design changes in thickness, shape, or layout when specifications of engines or accessories change, leading to delays and increased costs, especially during mass production.
Innovation Solution
A position regulating apparatus featuring a rod member with bent parts and receiving plates attached to the external frame, allowing for adjustable strength and shape without major design changes, where the rod member's ends collide with receiving plates to absorb energy and regulate position, and stays are used to attach the rod member to the engine block for increased flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bump stopper is designed as a fixed metal plate with reinforcement members, then the position regulation function is reliable, but any change in engine or accessory specifications requires significant redesign of the bump stopper thickness, shape, and layout
Solution Approach 1:
The bump stopper is changed from a fixed rigid structure to a rod member with bent parts that can be flexibly adjusted in shape and configuration. The rod member can be bent to different degrees and angles to accommodate various engine and accessory specifications while maintaining the position regulation function.
Solution Approach 2:
The invention allows changing the geometric parameters of the bump stopper by adjusting the bend angle and position of the rod member. Instead of redesigning the entire structure, only the bend parameters need to be modified to adapt to different specification requirements.
2Adaptability or versatility
If the bump stopper design is changed to accommodate specification modifications, then adaptability improves, but manufacturing complexity and development time increase
Solution Approach 1:
The bump stopper is segmented into a rod member with distinct bent parts, allowing independent adjustment of each bend section. This segmentation enables flexible configuration changes without requiring complete redesign of the entire structure.
Solution Approach 2:
The rod member incorporates bent parts with curved geometries instead of straight lines, enabling flexible positioning and angle adjustments. The curvature allows the bump stopper to adapt to various spatial requirements while maintaining structural integrity.
3Reliability
If the gap between the bump stopper and external frame is set for fast contact during impact, then protection function is improved, but the bump stopper may cause damage to the engine housing under certain conditions
Solution Approach 1:
The rod member with bent parts creates different local stiffness characteristics. The bent sections can be designed to have controlled flexibility, allowing the bump stopper to contact the external frame quickly for protection while distributing the impact force to prevent localized damage to the engine housing.
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 efficient regulation of the engine operating machine's position by absorbing collision energy and allowing for easy adjustments in strength and shape, reducing the need for extensive redesigns, thus minimizing delays and costs during production.
Implementation Method 1
the rod member has a crank shape having bent parts provided in positions deviated to the both ends from the center... the end of a rod member collides with a receiving plate, the bending moment acts on the rod member, and the energy of the collision is absorbed and reduced

AI summary
A position regulating apparatus has a generator body made of an engine and a generator driven by the engine, and a frame surrounding the periphery of the generator body. The frame is provided with a bump stopper as a rod member. The bump stopper is attached to a housing of the engine and disposed horizontally. The bump stopper regulates the position in the horizontal direction of the generator body within a preset range. Receiving plates disposed so as to face both end faces of the stopper body are provided. The round bar as the body of the bump stopper has a crank shape which reduces an impact by generating bending moment.
