Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power steering adjustment methods require multiple workers to check and adjust steering feeling while driving, making the process inefficient and labor-intensive.
Innovation Solution
A power steering adjustment device with a steering control information acquisition unit, calculation unit, mark information input unit, processing unit, and display unit that allows a single person to acquire, calculate, and display steering control information and mark adjustments on a graph, enabling easy and comfortable editing without needing many workers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional steering adjustment methods are used with multiple workers checking and adjusting steering feeling while driving, then steering feeling can be checked and adjusted, but the process becomes labor-intensive and inefficient
Solution Approach 1:
The patent creates a visual copy of steering control characteristics through graphs and charts that can be analyzed without actual driving. The adjustment information display unit generates graphical representations of steering feel data, allowing workers to review and make adjustments after a single test drive, eliminating the need for multiple workers to continuously monitor during driving.
Solution Approach 2:
The patent introduces an intermediary system consisting of the steering control information acquisition unit, calculation unit, and display unit. This intermediary automatically captures steering data during driving, processes it into visual graphs, and presents it for analysis, replacing the need for multiple human observers and recorders with an automated information processing system.
2Ease of operation
If visual inspection of steering characteristic charts is performed to grasp editing amounts intuitively, then steering feeling can be adjusted, but the process requires subjective judgment and lacks precision
Solution Approach 1:
The patent implements feedback by automatically calculating and displaying the differences between target steering characteristics and actual steering characteristics on the graphs. The adjustment information display unit shows visual feedback indicators that quantify how much adjustment is needed, combining intuitive visual display with precise automated calculation to guide workers in making accurate adjustments.
3Loss of information
If steering control information is manually recorded during driving by multiple workers, then adjustment data can be captured, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The patent replaces the mechanical system of manual data recording by multiple workers with an automated electronic information acquisition system. The steering control information acquisition unit automatically captures steering angle, torque, and other relevant parameters during driving, storing them without human intervention. This eliminates the time required for manual recording while ensuring complete and accurate data capture.

AI summary
A steering control information calculation unit (2) calculates a graph of steering control information in accordance with steering control information acquired by a steering control information acquisition unit (1). A mark information input unit (3) acquires mark information input by an adjusting person. A mark information processing unit (4) sets a mark on the graph of the steering control information when the mark information input unit (3) acquires the mark information. An adjustment information display unit (6) displays the graph of the steering control information and the mark set by the mark information processing unit (4) to be superimposed.
