Straddled Vehicle Receiver Layout for Storage Case Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional straddled vehicles face challenges in recognizing portable transmitters positioned outside a limited detection range of the receiver, requiring riders to move to operate switches far from the receiver, thereby complicating access to storage cases.
Innovation Solution
The straddled vehicle design positions the receiver lower than the seat and the switch rearward of the receiver, allowing easier recognition of portable transmitters and improved accessibility to storage cases by positioning the switch at the rear and front relative to the receiver, with the switch mounted to the vehicle body in a way that prevents passenger interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the receiver is disposed on the rear portion of the vehicle, then the storage case can be mounted on the rear, but the receiver cannot recognize the portable transmitter positioned at the front side of the vehicle
Solution Approach 1:
The receiver is positioned at the lower side of the vehicle body rather than at the rear, changing the spatial dimension of detection coverage. This vertical positioning allows the receiver to detect portable transmitters from a broader horizontal area including both front and rear positions, effectively expanding the detection range without compromising storage case accessibility.
2Volume of moving object
If the switch is disposed far away from the receiver, then the receiver can be positioned on the front portion, but the rider must move from front to rear to operate the switch
Solution Approach 1:
The switch is positioned at the rear side of the vehicle body, leveraging the vertical space created by the lower receiver position. This arrangement allows the switch to be accessible to riders seated on the vehicle without requiring movement between front and rear positions, eliminating time loss while maintaining expanded detection coverage.
3Volume of moving object
If the receiver is disposed on the front portion of the vehicle, then the detection range is improved, but the switch becomes inaccessible to riders positioned at the rear
Solution Approach 1:
The receiver is positioned at the lower side of the vehicle body, creating vertical space that allows the switch to be mounted at the rear side. This configuration enables riders at the rear to access the switch easily while the lower receiver position maintains broad detection coverage including front positions.

AI summary
A straddled vehicle, which can easily recognize a portable transmitter positioned around the straddled vehicle and can improve accessibility to a storage case, is provided. A straddled vehicle (1) is configured to change a locking state of a storage case (44) by detecting an identification signal from a portable transmitter (M). The straddled vehicle (1) is a vehicle frame (2), a rider seat (5), a bracket (45) of the storage case (44), a receiver (51) and a switch (52). The rider seat (5) is provided on the vehicle frame (2). The bracket (45) of the storage case (44) is disposed at a rear side than the rider seat (5). The receiver (51) is mounted to the vehicle frame (2) at a lower side than the rider seat (5). The switch (52) is mounted to the vehicle frame (2) at the rear side than the receiver (51) and at a front side than the bracket (45) of the storage case (44).
