Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor holders for electric motors in utility vehicles lack a simple and secure fastening solution that accommodates the structural differences between electric motors and internal combustion engines, necessitating an improved mounting system.
Innovation Solution
A holding device with L-shaped motor holders having a first and second fastening region, where the second region is spaced below the longitudinal members to achieve a low installation position, potentially lowering the vehicle's center of gravity, and incorporating a resilient bearing for vibration damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the motor holder is designed with high load-bearing capacity and stiffness to secure the motor, then the mounting stability is improved, but the device complexity increases
Solution Approach 1:
The motor holder is divided into two separate L-shaped holders that can be independently mounted to the longitudinal members. Each holder can be separately adjusted and secured, allowing the mounting system to achieve high stability through multiple discrete connection points rather than a single complex rigid structure.
Solution Approach 2:
The motor holders incorporate adjustable positioning mechanisms that allow dynamic adaptation to different motor configurations and mounting requirements. This adjustability enables the same holder design to accommodate varying load conditions without requiring multiple specialized components.
2Stability of the object's composition
If the second fastening region is arranged below the longitudinal members to lower the vehicle center of gravity, then the driving behavior is improved, but the spacer length increases
Solution Approach 1:
The L-shaped motor holders extend in multiple directions (both horizontally along the longitudinal members and vertically downward), utilizing three-dimensional space efficiently. This spatial arrangement achieves the center of gravity lowering function without requiring excessively long spacers, as the vertical dimension is exploited through the L-shape geometry rather than单纯 increasing linear length.
3Device complexity
If conventional motor holders are used for electric motors, then the mounting system is simple, but the mounting security is insufficient due to structural differences between electric motors and internal combustion engines
Solution Approach 1:
The L-shaped motor holder design serves multiple functions: it provides secure attachment to the vehicle frame through the first fastening region, accommodates the motor through the second fastening region, enables vertical positioning adjustment, and allows for center of gravity optimization. This multi-functional design replaces the need for multiple specialized components while maintaining mounting security.
