Swing-Linked Rear Carrier for Stable Forward Load Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear carriers for saddled vehicles face difficulties in concentrating mass when the carrier member is moved forward due to its position being higher than the rear seat, leading to instability and exposure issues.
Innovation Solution
A rear carrier design featuring a swing member and carrier member that can move between front and rear positions, supported by a grab rail, with lock mechanisms to stabilize the position and engage with the seat for secure support, and a protection member to prevent exposure and water ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the carrier member is positioned at a higher location on the rear carrier, then the carrier member can move freely in the front-rear direction, but mass concentration becomes difficult and stability deteriorates
Solution Approach 1:
The patent applies a swing member that allows the carrier member to dynamically change position between front and rear locations. The swing member pivots on the grab rail, enabling the carrier to move forward for accessibility or rearward for mass concentration, resolving the contradiction between operability and stability through dynamic repositioning
Solution Approach 2:
The swing member acts as an intermediary mechanism between the fixed grab rail and the movable carrier member. It mediates the transition between high-position frontward movement and low-position rearward mass concentration, allowing the system to achieve both ease of operation and stability at different operational states
2Ease of operation
If the carrier member is moved to the front position, then accessibility is improved, but the carrier member becomes unstable and exposed to external elements
Solution Approach 1:
The swing member enables dynamic positioning of the carrier between front (accessible) and rear (protected) positions. When accessibility is needed, the carrier swings forward; when protection is needed, it swings rearward toward the seat, resolving the contradiction between accessibility and protection from external elements
Solution Approach 2:
The swing member serves as an intermediary that allows the carrier to transition between exposed front position and protected rear position near the seat. This intermediary mechanism provides both accessibility when needed and protection from water ingress when repositioned rearward
3Stability of the object's composition
If a lock mechanism is added to stabilize the carrier position, then stability is improved, but the device complexity increases
Solution Approach 1:
The lock mechanism is designed to be self-locking through elastic biasing. The elastic member automatically engages the locking pin with the positioning holes when the carrier reaches front or rear positions, providing automatic stabilization without requiring additional actuators or complex control systems
Solution Approach 2:
The lock mechanism uses simple, inexpensive components: a locking pin, elastic member, and positioning holes. These simple elements provide effective stabilization without adding significant complexity, treating the locking function as a simple mechanical feature rather than a complex system
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables stable mass concentration and improved appearance by allowing the carrier to be positioned lower and securely engaged with the seat, while simplifying operation and protecting against water ingress.
Implementation Method 1
biased toward a locking side by an elastic member
Implementation Method 2
The swing member is swingably supported on its one end side by the grab rail, and is swingably supported on its opposite side by the carrier member

AI summary
Provided is a rear carrier that facilitates mass concentration when a carrier member movable in a front-rear direction is moved frontward. A rear carrier for a saddled vehicle includes a swing member and a carrier member. The swing member is supported by a grab rail fixed to a rear portion of a vehicle body. The carrier member is supported by the swing member. The swing member is swingably supported on its one end side by the grab rail, and is swingably supported on its opposite side by the carrier member. Swinging of the swing member enables the carrier member to move between a front-side position and a rear-side position. When the carrier member is set at the front-side position, the carrier member is supported by a seat of the saddled vehicle.
