Steering Device Bracket Segmentation and Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering devices face challenges in maintaining the relative positions of brackets during transportation and assembly, leading to potential misalignment and decreased assembling efficiency, while also being bulky and heavy due to integrated bracket configurations that compromise strength and driving feel.
Innovation Solution
A steering device design featuring a column unit with a front bracket and rear bracket connected by a fixed connection piece, which restricts rotation and includes a tilt guide hole for upward and downward movement, allowing for size reduction and weight reduction while maintaining strength and assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If separate front bracket and rear bracket are used, then size and weight are reduced, but relative position stability deteriorates
Solution Approach 1:
The bracket system is divided into separate front bracket and rear bracket components, each performing specific functions. The front bracket supports the column unit for rotation, while the rear bracket provides additional support and positioning, allowing weight reduction while maintaining functional stability through proper segmentation
Solution Approach 2:
A connection piece is introduced as an intermediary component between the front bracket and rear bracket. This connection piece maintains the relative position and angle between the two brackets, preventing rotation and misalignment while allowing the brackets to remain separate for weight reduction
2Stability of the object's composition
If integrated bracket is used, then relative position stability is improved, but size and weight increase
Solution Approach 1:
The integrated bracket is segmented into separate front and rear bracket components connected by a connection piece, reducing overall weight while maintaining the structural stability and relative position control that an integrated design would provide
Solution Approach 2:
The connection piece acts as a mediator that replaces the need for a fully integrated bracket structure, maintaining relative position stability between front and rear brackets while allowing for weight reduction through separation
3Weight of moving object
If integrated bracket is thinned, then size and weight are reduced, but strength deteriorates
Solution Approach 1:
By segmenting the bracket into separate components (front bracket, rear bracket, and connection piece), each component can be optimized for its specific function with appropriate thickness and strength, avoiding the need to thin the entire integrated bracket structure
Solution Approach 2:
The connection piece serves as an intermediary that maintains structural integrity between the front and rear brackets, allowing the brackets themselves to be thinner for weight reduction while the connection piece ensures overall strength and stability

AI summary
A steering device according to an aspect of the present disclosure includes: a column unit configured to rotatably support a steering shaft; a front bracket configured to rotatably support the column unit; a lock bolt configured to protrude in a right-left direction from the column unit; a rear bracket that includes a tilt guide hole and is attached to a vehicle body behind the front bracket, the tilt guide hole guiding the lock bolt to move upward and downward as the column unit rotates around an axis; and a connection piece bridged between the front bracket and the rear bracket in a state of being fixed to each of the front bracket and the rear bracket.
