Engine Bracket Fastening Parts with Shared Bosses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internal combustion engines face weight increase due to redundant bracket fastening parts, which are necessary for accommodating various auxiliary equipment attachments across different vehicle models and applications.
Innovation Solution
The engine design incorporates a pair of bracket fastening parts sharing bosses and ribs arranged in a convex polygonal pattern, allowing for adaptable attachment configurations while minimizing weight by sharing material and reducing redundant components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple bracket fastening parts are provided separately for different applications, then the engine can accommodate various auxiliary equipment attachments, but the weight of the engine increases
Solution Approach 1:
The patent merges multiple bracket fastening parts into a single integrated fastening part that includes multiple fastening regions. Each region can independently support different brackets or auxiliary equipment, eliminating the need for separate fastening parts for different applications. This integration reduces the overall weight while maintaining adaptability for various mounting configurations.
Solution Approach 2:
The integrated bracket fastening part is designed with multiple fastening regions that can accommodate different types of brackets and auxiliary equipment. Each region has its own boss and rib structure, allowing the single fastening part to serve multiple functions and support various engine applications without requiring separate dedicated fastening parts for each application.
2Adaptability or versatility
If separate bracket fastening parts are provided for different applications, then the engine can be used for multiple applications, but the structural complexity increases
Solution Approach 1:
The patent combines multiple separate bracket fastening parts into a single integrated structure that includes multiple fastening regions. Each region maintains its own boss and rib configuration for independent bracket mounting, but they are unified within one continuous structural component. This reduces the number of separate parts and simplifies the overall structure while preserving multi-application capability.
3Adaptability or versatility
If redundant bosses are provided for different bracket fastening parts, then various brackets can be attached in different ways, but the weight increases
Solution Approach 1:
The patent integrates multiple bosses into a single unified boss structure that serves multiple fastening regions. The boss is designed with appropriate thickness and reinforcement to support brackets attached at different regions, eliminating the need for multiple separate bosses. This reduces the total material required while maintaining the capability for various bracket attachment configurations.

AI summary
A pair of bracket fastening parts (7, 12, 91, 92, 121, 122, 161, 162) are provided on a side of the main body in an adjoining relationship, each bracket fastening part including a plurality of bosses (32 to 35, 72 to 75, 102 to 106, 132 to 137) arranged in a convex polygonal pattern and a plurality of ribs (37 to 42, 60, 80 to 84, 110 to 115, 140 to 146) connecting the bosses in a prescribed pattern. At least two of the bosses of one of the bracket fastening parts are shared by an adjoining one of the bracket fastening parts. Thereby, the engine can be adapted for multiple applications while minimizing an increase in the weight of the engine.
