Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hollow athletic balls, such as basketballs and soccer balls, face challenges in embedding sensors at a central position without altering the center of mass and risking sensor damage from thermal treatment during manufacturing.
Innovation Solution
A sensor assembling structure with thermal insulation materials and connecting members that securely place a sensor at the center of the hollow ball, using a thermal insulation coat to prevent heat damage and maintain the ball's center of mass, comprising multiple connecting members and fastening joints that keep the sensor and insulation coat in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor is embedded inside a hollow athletic ball, then data collection capability is improved, but the sensor may be damaged by heat from thermal treatment during manufacturing
Solution Approach 1:
A thermal insulation coat is introduced as an intermediary layer between the sensor and the ball's thermal treatment process. This coat acts as a heat barrier, allowing the thermal treatment to proceed while protecting the sensor from excessive heat exposure that would cause damage.
Solution Approach 2:
The thermal insulation coat is installed on the sensor before the thermal treatment process begins. This preliminary protective measure ensures that when heat is applied during manufacturing, the sensor is already shielded and prevented from thermal damage.
2Reliability
If a sensor is placed inside a hollow athletic ball, then detecting function is improved, but the center of mass position may be altered affecting flight path
Solution Approach 1:
The sensor assembly is positioned asymmetrically within the hollow ball structure, specifically at the center of mass location. The connecting members are strategically arranged to balance the added weight of the sensor and insulation coat, ensuring the center of mass remains at the geometric center of the ball, thus maintaining proper flight characteristics.
Solution Approach 2:
The thermal insulation coat is applied locally around the sensor rather than throughout the entire ball. This localized approach minimizes the overall weight addition and allows precise positioning of the sensor assembly at the center of mass without requiring modifications to the entire ball structure.
3Manufacturing precision
If connecting members are used to secure the sensor, then sensor positioning is improved, but device complexity increases
Solution Approach 1:
The securing structure is divided into multiple discrete connecting members rather than a single complex fixture. Each connecting member is a simple component that individually secures the sensor assembly to the ball's inner surface, making the overall system easier to manufacture and assemble while achieving precise positioning.
