Solution Overview

Problem

Existing wheel clamping systems for motor vehicle wheels on balancers are inconvenient to use, as they require holding the wheel and actuating a foot pedal simultaneously, and may risk deforming the wheel rim during clamping due to over-tightening.

Innovation Solution

A wheel clamping system with a handle equipped with a force detecting device that wirelessly communicates with the balancer's actuator to control clamping and unclamping operations, ensuring a predefined force is applied to the wheel rim, and a force detecting device integrated into the wheel clamping system to monitor and control the clamping force, preventing rim deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a foot pedal is used to actuate the clamping mechanism, then the clamping operation can be performed, but the operator cannot simultaneously hold the wheel and actuate the pedal, and the pedal may be obstructed from view by the wheel

Engineering Contradiction:
Improveconvenience of clamping operationVSAvoidcomplexity of control mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical foot pedal actuation system with a wireless electronic control system. The handle incorporates a force detecting device that senses when clamping force is applied, and a signal emitter that wirelessly transmits activation signals to the actuator, eliminating the need for mechanical foot pedal connection and improving operational convenience.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a wireless signal as an intermediary between the operator's manual action on the handle and the actuator. The force detecting device and signal emitter act as intermediaries that convert mechanical force into wireless control signals, allowing remote activation of the clamping mechanism without direct mechanical connection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If manual clamping force is applied without control, then the clamping operation can be performed, but the wheel rim may be deformed due to over-tightening

Engineering Contradiction:
Improveclamping operation efficiencyVSAvoidrim deformation risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent incorporates a force detecting device in the handle that provides feedback on the clamping force being applied. This feedback mechanism monitors the force in real-time and can prevent over-tightening by signaling when the appropriate clamping force has been reached, thereby protecting the wheel rim from deformation while maintaining efficient operation.

Inventive Principle:
Principle #23Feedback
