Tire Cavity Length Calculation for Sound-Absorbing Member Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The thickness of the tread portion of pneumatic tires varies by type, making it difficult to accurately determine the circumferential length of the tire inner cavity surface solely based on size information stamped on the sidewall, which complicates the process of retrofitting sound-absorbing members like annular sponges for noise reduction.
Innovation Solution
An information processing system that acquires shape identification information from RFID tags, barcodes, or cameras to calculate the circumferential length of the tire inner cavity surface, using pre-stored data to determine the appropriate sound-absorbing member dimensions for accurate installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If size information stamped on the sidewall is used to determine circumferential length, then the process is simple, but the measurement precision is insufficient due to varying tread thickness
Solution Approach 1:
The system pre-stores tread thickness data for multiple tire types in a database before the actual measurement process. When a tire is scanned, the system retrieves the pre-stored thickness data corresponding to that tire type, eliminating the need for manual measurement during the retrofit process and ensuring accurate circumferential length calculation.
Solution Approach 2:
The system introduces a database as an intermediary between the tire size information and the circumferential length calculation. The database stores the relationship between tire types, tread thicknesses, and circumferential lengths, allowing the system to accurately determine circumferential length by querying the database with scanned tire information rather than relying on direct measurement or simple calculations.
2Measurement precision
If manual identification of tire type and examination of tread thickness is performed, then the measurement precision is improved, but the productivity decreases due to increased work burden
Solution Approach 1:
The system enables self-service by allowing the tire information and circumferential length data to be automatically retrieved and processed through scanning. The salesclerk simply scans the tire sidewall, and the system automatically identifies the tire type, retrieves the corresponding tread thickness from the database, and calculates the circumferential length, eliminating manual identification and examination work.
Solution Approach 2:
The system replaces the manual mechanical process of identifying tire types and measuring tread thickness with an automated optical scanning system. The scanner reads the tire sidewall information, and the system processes this data through database queries to automatically determine the circumferential length, substituting human manual work with automated technological processes.
3Reliability
If accurate circumferential length information is obtained through manual processes, then the reliability of sound-absorbing member installation is improved, but the loss of time increases due to detailed examination requirements
Solution Approach 1:
The system performs preliminary actions by pre-storing all necessary tire type information, tread thickness data, and circumferential length calculations in a database before the actual installation process. This allows rapid retrieval and accurate determination during the retrofit process without requiring time-consuming manual identification and measurement.
Solution Approach 2:
The system creates equipotentiality by standardizing the data structure and relationships in the database, allowing uniform and rapid access to circumferential length information for different tire types. This standardized approach ensures consistent accuracy across all tire types while maintaining uniform processing speed, eliminating the need for varying levels of manual examination effort.
