Removable Vehicle Backrest Tool-Free Installation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing removable backrests for straddle-type vehicles require tools for installation and removal, which is inconvenient for users who want to adjust the backrest based on passenger presence.
Innovation Solution
A backrest design featuring arms with sliding portions and biasing members that allow for tool-free installation and removal by compressing or extending to align posts with slots, using straps and hooks for secure attachment to the vehicle frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional backrests are installed on straddle-type vehicles, then passenger comfort is improved, but tool-free installation and removal cannot be achieved
Solution Approach 1:
The backrest arms incorporate sliding portions that can move relative to the arm bodies, allowing the arms to dynamically adjust their configuration during installation and removal. The biasing members enable the arms to transition between extended and retracted states, facilitating tool-free attachment and detachment while maintaining structural integrity when installed.
Solution Approach 2:
The backrest is divided into multiple independent components including arms, sliding portions, biasing members, posts, and slots. This segmentation allows each component to perform its specific function independently, enabling the arms to slide and extend/retract without requiring tools, while still providing a secure installed structure.
2Ease of operation
If the backrest is made removable for flexibility, then ease of installation and removal is improved, but secure attachment to the frame is compromised
Solution Approach 1:
The biasing members automatically engage the sliding portions with the posts when the arms are in the extended position, creating a self-locking mechanism that secures the backrest to the frame without requiring tools or additional fasteners. The elastic force of the biasing members maintains constant pressure to ensure reliable attachment while allowing easy removal when force is applied.
3Ease of operation
If the backrest structure is simplified for easy installation, then ease of operation is improved, but structural stability is reduced
Solution Approach 1:
The sliding portions provide dynamic adjustment capability that allows the arms to accommodate variations in post positions and absorb installation tolerances. This dynamic feature enables simple tool-free installation while maintaining stable attachment once installed, as the sliding portions can settle into secure engagement positions.
Solution Approach 2:
The backrest structure combines rigid components (arm bodies, back support) with flexible elements (sliding portions, biasing members) to create a composite structure that is both easy to install and stable when installed. The rigid parts provide structural integrity while the flexible parts enable simple operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and secure installation and removal of the backrest without tools, enhancing user convenience and flexibility.
Implementation Method 1
a biasing member disposed between the first and second portions. The first posts is received in the first slots and abutting the first portions. The second posts is received in the second slots and abutting the second portions. The biasing members bias the first portions toward the first posts and the second portions toward the second posts.

AI summary
A backrest for selectively connecting to a frame of a vehicle having a straddle seat has a back support, and first and second arms connected to the back support and extending forward thereof. Each of the arms has a first portion at least partially defining a first slot, a second portion slidably connected to the first portion, and a biasing member disposed between the first and second portions. The second portion defines a second slot. The first and second slots open in opposite directions. A vehicle having the backrest and a method of installing the backrest on a vehicle are also disclosed.
