Adjustable Load Sensor Calibration Tool for Vehicle Variants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load sensors require specific calibration tools for each vehicle configuration due to varying calibration distances, leading to inefficiencies and potential loss of parts during calibration.
Innovation Solution
A versatile tool with a first and second engagement member, allowing adjustable axial positions, is used to hold the lever in a fixed position during calibration, enabling calibration across different vehicle configurations without part separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a specific calibration tool is designed for each vehicle configuration, then the calibration precision is improved, but the device complexity and inventory requirements increase
Solution Approach 1:
The calibration tool is designed with a movable second part that can be positioned at multiple predefined axial positions, allowing a single tool to accommodate different calibration distances for various vehicle configurations. This eliminates the need for multiple specialized tools while maintaining calibration precision across different applications.
Solution Approach 2:
The second part of the calibration tool is made movable relative to the first part along an axis, enabling dynamic adjustment between at least two predefined axial positions. This dynamic capability allows the tool to adapt to different calibration distances without requiring multiple static tool variants.
2Ease of operation
If the calibration tool parts are made separable, then the ease of storage is improved, but the risk of part loss and displacement increases
Solution Approach 1:
The calibration tool is designed with a nested structure where the second part can be positioned within or alongside the first part when not in use. The irremovable connection ensures that even though the parts can move relative to each other during operation, they remain permanently attached, eliminating the risk of part loss while maintaining storage compactness.
3Adaptability or versatility
If multiple calibration tools are maintained for different configurations, then the adaptability is improved, but the loss of time for tool selection and management increases
Solution Approach 1:
A single calibration tool is designed to handle multiple vehicle configurations through the movable second part that can be adjusted to different predefined axial positions. This universality eliminates the need for technicians to select from multiple specialized tools, reducing time loss while maintaining adaptability to different calibration distances.
