Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intake control devices for straddle-type vehicles face complexity in processing due to the need for precise control of actuators based on potentiometer readings, leading to challenges in maintaining the position of moving intake pipes amidst vibrations during vehicle travel.
Innovation Solution
An intake control device with a stationary intake pipe, a moving intake pipe, an actuator, and a control unit that inhibits the moving intake pipe from exceeding a set position, energizing it to maintain the set position, either connected or separated, using a stopper mechanism and intermittent energization, and adjusting based on vehicle traveling state detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the moving intake pipe is inhibited from moving beyond the set position using a stopper mechanism, then the positional stability is improved, but the device complexity increases
Solution Approach 1:
The system uses the actuator's own driving force to maintain the intake pipe at the set position through intermittent energization, eliminating the need for external stopper mechanisms or complex positioning devices. The actuator serves dual purposes: moving the pipe and maintaining its position.
Solution Approach 2:
The control unit intermittently energizes the actuator to maintain the intake pipe at the set position. This periodic activation compensates for vibrations and external forces without requiring continuous power or complex mechanical retention structures.
2Use of energy by moving object
If intermittent energization is used to maintain the set position, then the energy usage is optimized, but the control precision may be compromised
Solution Approach 1:
The control unit monitors the position of the moving intake pipe and adjusts the intermittent energization of the actuator accordingly. This feedback mechanism ensures that the pipe remains at the set position with high precision while minimizing energy consumption through targeted, periodic activation.
Solution Approach 2:
The system transitions from static continuous positioning to dynamic intermittent positioning. The actuator is activated only when needed to counteract vibrations or maintain position, adapting its operation to real-time conditions rather than operating continuously.
3Use of energy by moving object
If the actuator is driven with smaller driving force when the moving intake pipe is at the set position, then the energy consumption is reduced, but the responsiveness to external disturbances may be reduced
Solution Approach 1:
The actuator is intermittently energized with smaller driving forces when the intake pipe is at the set position. This periodic activation provides sufficient responsiveness to counteract vibrations and external disturbances while significantly reducing overall energy consumption compared to continuous full-power operation.
Solution Approach 2:
The control unit adjusts the driving force parameters of the actuator based on the position of the intake pipe. When at the set position, smaller intermittent forces are applied; during movement, larger forces are used. This parameter adaptation optimizes both energy efficiency and responsiveness.
