Drive Mechanism for Compact Vehicle Accessories
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle drive systems face challenges in accommodating additional rotary-powered components, especially in compact vehicles, as existing components are not easily accessible for drive power and often only engage when the vehicle is in gear, limiting the installation of accessories like air conditioning systems, alternators, and hydraulic pumps.
Innovation Solution
A drive mechanism that connects to existing rotary components, utilizing a drive shaft with a support structure and pulley system to facilitate the operation of accessory components, allowing for the installation of additional accessories like air conditioning compressors, alternators, and hydraulic pumps, even when the vehicle is idling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional rotary-powered components are added to existing vehicle drive systems, then the functionality and utility of the vehicle is improved, but the device complexity and space requirements increase
Solution Approach 1:
The drive shaft is nested within the housing of an existing rotary component (such as an alternator or power steering pump), allowing the new drive mechanism to be integrated into the existing component's space rather than requiring separate mounting space. This nesting approach enables additional functionality while minimizing increases in device complexity and spatial requirements.
Solution Approach 2:
The drive shaft mechanism is designed with universal adaptability to connect to multiple types of existing rotary components through various mounting configurations. The support structure can accommodate different component housings and rotation axes, allowing a single drive mechanism design to serve multiple functions and component types, thereby improving versatility without proportionally increasing complexity.
2Ease of manufacture
If existing rotary components are made accessible for drive power, then accessory installation is facilitated, but the ease of operation and maintenance of existing components may be compromised
Solution Approach 1:
The existing rotary component is functionally segmented into two independent parts: the original component housing and the newly added drive shaft assembly. The drive shaft can be independently installed, removed, and maintained without disassembling or interfering with the existing component's internal mechanisms. This segmentation allows accessory installation while preserving the original component's ease of operation and maintenance.
Solution Approach 2:
The drive shaft acts as an intermediary element that bridges the existing rotary component's rotation to new accessory components. It connects to the existing component through a support structure that interfaces with the housing, allowing power transmission without requiring direct modification to the existing component's operational elements. This intermediary approach facilitates accessory installation while maintaining original component operability.
3Use of energy by moving object
If drive components are designed to engage only when vehicle is in gear, then engine power is efficiently utilized, but the availability of rotary power for accessories during idle is limited
Solution Approach 1:
The drive shaft mechanism is designed with dynamic engagement capability that is independent of the vehicle's transmission state. The support structure allows the drive shaft to rotate freely and engage accessory components regardless of whether the vehicle is in gear or idle. This dynamic design decouples the accessory drive availability from the transmission engagement state, enabling continuous rotary power availability while maintaining energy efficiency through proper belt tensioning and component design.
