Bowling Ball Indicia Integration via Preformed Core Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for adding indicia to bowling balls often result in weight distribution issues, durability problems, and increased manufacturing complexity, including the use of different materials that can crack or break, and require additional steps that raise costs and compromise performance.
Innovation Solution
A method involving a preformed indicia member with a backing structure and design elements, attached to the bowling ball core via posts or adhesive, is molded within a cover stock to create a visually integrated and balanced bowling ball with reduced air entrapment, using materials that match or closely resemble the outer layer for consistency and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If indicia are added by engraving or etching and filling with different colored substance, then visual appearance is improved, but weight distribution and structural integrity deteriorate
Solution Approach 1:
The indicia member is segmented into a backing structure and design elements, allowing it to be attached to the core while maintaining weight balance. The backing structure distributes weight evenly, preventing the concentration issues that arise from filling engraved areas with different materials.
Solution Approach 2:
The indicia member combines multiple functions into a single component: it provides visual design, maintains weight distribution, and attaches to the core structure. This merging eliminates the need for separate engraving and filling steps that compromise structural integrity.
2Illumination intensity
If multiple steps are used to add indicia (etching, filling, drilling, cutting, attaching), then visual appearance is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The indicia member is pre-formed with the backing structure and design elements before attachment to the core. This preliminary preparation allows for simplified assembly during manufacturing, eliminating the need for complex post-processing steps like engraving, filling, and multiple attachments.
3Illumination intensity
If different materials are used for indicia filler and outer layer, then visual appearance is improved, but durability and reliability deteriorate
Solution Approach 1:
The backing structure of the indicia member is made from material that matches or closely resembles the outer layer material, ensuring homogeneous properties throughout. This prevents the durability issues and cracking that occur when different materials with incompatible properties are joined together.

AI summary
A bowling ball with an indicia is provided. A method for manufacturing such a bowling ball is also provided. The indicia may be preformed and attached to the core of the bowling ball before the outer layer of the bowling ball is created.
