Vehicle Assembly Member Positioning for Thermal and Mud Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an arrangement that allows the assembly member in a vehicle to be positioned appropriately relative to peripheral members while avoiding thermal damage and mud accumulation, and ensuring protection from impacts.
Innovation Solution
The arrangement includes a power unit, propeller shaft, differential, switch, operation side transmission members, and a device side transmission member connected to an assembly member positioned opposite an exhaust pipe, with a rear floor and lid configuration that facilitates cable adjustment and mud prevention, and a support member structure that absorbs impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the assembly member is positioned near the exhaust pipe, then it is easier to connect transmission members, but it is exposed to thermal damage and mud accumulation
Solution Approach 1:
The patent introduces a rear floor as an intermediary structure between the assembly member and the harmful environment. The rear floor is positioned to cover the assembly member, creating a protective barrier that blocks mud accumulation while allowing the assembly member to remain in its optimal position for connecting transmission members. The lid on the rear floor provides additional protection while maintaining accessibility.
2Object-affected harmful factors
If the assembly member is positioned to avoid thermal damage and mud, then it is protected from harmful factors, but it becomes difficult to connect transmission members
Solution Approach 1:
The patent divides the protective structure into segmented components: a rear floor that provides primary protection, and a lid that can be opened or removed. This segmentation allows the assembly member to remain protected during normal operation while enabling easy access when connection or maintenance is required. The lid can be opened to expose the assembly member for connecting transmission members without compromising the overall protective structure.
3Object-affected harmful factors
If the rear floor is made solid for protection, then it prevents mud accumulation, but it becomes difficult to access the assembly member for cable adjustment
Solution Approach 1:
The patent makes the rear floor dynamic by introducing a lid that can change its state between closed and open positions. When closed, the lid provides complete protection against mud accumulation. When opened, it allows easy access to the assembly member for cable adjustment and maintenance. This dynamic structure resolves the contradiction between protection and accessibility by allowing the system to adapt to different operational requirements.

AI summary
An arrangement for an assembly member of a vehicle includes a power unit for generating a driving force; a pair of left and right driving wheels; a propeller shaft extending in the forward and backward direction of the vehicle; a differential for transmitting the driving force to the pair of left and right driving wheels via a pair of left and right drive shafts; a switch for switching the diff-lock of the differential on and off; an exhaust pipe disposed on one side in the vehicle width direction with respect to the propeller shaft; and an assembly member for operating the switch via each of a plurality of operation side transmission members and a device side transmission member using an operating force applied to each of a plurality of operating elements; wherein the assembly member is disposed on the opposite side of the propeller shaft as the exhaust pipe.
