Wheel Balance Weight Bonding with Pressing Force Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balance weight pressure-bonding devices lack control over the pressing force, leading to instability in bonding balance weights to wheel rims, which can result in inconsistent bonding quality.
Innovation Solution
A balance weight pressure-bonding device equipped with a pressing member, a pressing force sensor, a drive unit, and a controller that regulates the pressing force to ensure stable bonding by detecting and maintaining a predetermined force during the bonding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a roller is used to press the balance weight against the wheel rim, then the balance weight can be pressure-bonded to the inner circumferential surface, but the pressing force cannot be controlled and varies for each wheel
Solution Approach 1:
The patent employs a feedback control system where a pressing force sensor detects the actual pressing force applied to the balance weight, and a controller adjusts the drive unit to maintain the pressing force within a predetermined range. This closed-loop feedback mechanism ensures consistent bonding quality across different wheels while providing precise control over the pressing force.
Solution Approach 2:
The patent replaces the simple mechanical roller pressing system with a controlled actuation system that includes a drive unit (such as a linear actuator or motor), a pressing force sensor, and a controller. This substitution introduces active control capability, allowing the pressing force to be precisely regulated rather than relying solely on passive mechanical contact.
2Strength
If the pressing force is increased to ensure bonding, then bonding strength improves, but the pressing force becomes uncontrolled and inconsistent across different wheels
Solution Approach 1:
The pressing force sensor continuously monitors the actual pressing force during the bonding process and feeds this information back to the controller. The controller then adjusts the drive unit to maintain the pressing force within the optimal predetermined range, ensuring both sufficient bonding strength and consistent force application across all wheels.
Solution Approach 2:
The patent dynamically adjusts the pressing force parameter during the bonding process based on real-time sensor feedback. By changing the pressing force from a fixed mechanical value to a controllable variable parameter, the system can optimize bonding strength while maintaining consistency across different wheels and conditions.

AI summary
A balance weight pressure-bonding device pressure-bonds, to an inner circumferential surface of a wheel, a balance weight which is to be attached to the inner circumferential surface of the wheel. The balance weight pressure-bonding device includes a pressing member that has a pressing surface arranged to press the balance weight against the inner circumferential surface of the wheel in a state in which the balance weight is sandwiched between the pressing surface and the inner circumferential surface of the wheel, a pressing force sensor that detects a pressing force with which the pressing surface presses the balance weight during pressing of the balance weight by the pressing member, a drive unit that drives the pressing member, and a controller that controls the drive unit. The controller drives the drive unit and causes the pressing surface to press the balance weight against the inner circumferential surface of the wheel and pressure-bond the balance weight to the inner circumferential surface of the wheel, based on detection of the pressing force by the pressing force sensor.
