Air Conditioner Mounting Stay for Tubular Vehicle Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mounting an air conditioner unit stably on a tubular vehicle body frame, particularly in vehicles designed for rough terrain, is challenging due to the tubular frame's structure.
Innovation Solution
The air conditioner unit is mounted to the tubular frame via a stay that includes a board-shaped plate portion and tubular portions, which are fixed to the frame using extension portions and elastic members, allowing for stable and easy mounting while absorbing vibrations and reducing weight and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the air conditioner unit is mounted directly to the tubular frame, then the mounting structure is simple, but the mounting stability is poor
Solution Approach 1:
The patent introduces an intermediate member (casing with mounting legs) that serves as a mediator between the air conditioner unit and the tubular frame. The mounting legs extend along the upper-lower direction and protrude downward to engage with the tubular frame, providing stable mounting while keeping the overall structure manageable.
2Stability of the object's composition
If the air conditioner unit is mounted to the tubular frame using a stay, then the mounting stability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the stay function with the casing structure. The casing is integrally formed with mounting legs that serve as the stay, combining the housing and mounting functions into a single integrated component. This reduces the number of separate parts while maintaining mounting stability on the tubular frame.
3Stability of the object's composition
If the mounting legs are made long to improve mounting stability on the tubular frame, then the stability is improved, but the weight of the air conditioner unit increases
Solution Approach 1:
The patent applies local quality by making the mounting legs extend only in the upper-lower direction where needed for engagement with the tubular frame, rather than uniformly increasing the size of the entire casing. The legs are positioned specifically at locations that provide optimal mounting stability while minimizing additional material and weight.
