Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire throttle adjustment mechanisms require frequent maintenance due to wire stretching and position displacement between the throttle valve and operation member, leading to discordance in operation states and prolonged assembly times, especially with individual differences in wire length.
Innovation Solution
The introduction of an elastically deformable operation member with an elastic arm part and a wire guide, which absorbs stretching and position displacement, allowing for constant full-open throttle valve operation without complex adjustments, and initializes the operation state quickly even with varying wire lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire throttle adjustment mechanism is used, then the throttle valve can be adjusted from idling to fully-opened state, but wire stretching and position displacement occur during repeated use, leading to loss of adjustment precision
Solution Approach 1:
The patent changes the physical state of the connection between wire and operation member from rigid to elastic. The elastic arm part allows dynamic parameter adjustment through elastic deformation, compensating for wire stretching and position displacement that occur during repeated use, thereby maintaining adjustment precision throughout the service life.
Solution Approach 2:
The elastic arm part acts as a pre-designed cushioning element that anticipates and absorbs the effects of wire stretching and position displacement before they cause adjustment precision loss. This beforehand cushioning mechanism ensures reliable adjustment precision throughout the entire service life of the wire.
2Manufacturing precision
If a position adjustment device is provided at the relay point of the wire, then appropriate throttle valve positions can be set, but the device complexity increases and maintenance is required
Solution Approach 1:
The elastic arm part provides self-adjusting functionality that eliminates the need for separate position adjustment devices. The elastic deformation automatically compensates for wire stretching and position displacement, making the system self-maintaining and eliminating complex adjustment mechanisms while preserving throttle valve position accuracy.
Solution Approach 2:
The patent extracts the adjustment function from a separate position adjustment device and integrates it into the operation member itself through the elastic arm part. This extraction simplifies the overall device complexity while maintaining manufacturing precision by making the adjustment function inherent to the operation member.
3Reliability
If elaborate adjustment of wire connection position is performed during assembly, then appropriate initial operation state can be achieved, but assembly time increases
Solution Approach 1:
The elastic arm part provides self-adjusting functionality during assembly that eliminates the need for elaborate manual adjustment of wire connection positions. The elastic deformation automatically compensates for individual wire length differences, enabling rapid assembly while ensuring accurate initial operation state through self-calibration during first use.
Solution Approach 2:
The elastic arm part is pre-configured to provide elastic deformation compensation that automatically corrects any initial position variations. This preliminary action of elastic deformation ensures accurate initial operation state without requiring time-consuming elaborate adjustment during assembly, thereby improving assembly speed while maintaining reliability.
