Rotating E-Bike Carrier Arm for Easier Loading and Stable Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bike carriers struggle to efficiently load and stabilize e-bikes due to their increased weight and width, and the vertical arm of traditional carriers can obstruct the loading process, while sudden vehicle movements cause e-bikes to tilt or shift due to inertia.
Innovation Solution
A carrier device with a supporting member and an arm member that includes a carrier element, a rotation element, and a pivot control element, allowing the arm member to rotate between loading and unloading positions, and features height adjustment and locking mechanisms to stabilize the e-bike during loading and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vertical arm structure is used in traditional bike carriers, then the carrier can support the bike, but the vertical arm becomes an obstacle to the movement of the bike during loading
Solution Approach 1:
The patent applies the dynamics principle by making the arm member rotatable between a first position (parallel to reception elements for loading) and a second position (perpendicular to reception elements for holding). This dynamic repositioning eliminates the obstruction problem during loading while maintaining structural support capability, directly resolving the contradiction between ease of loading and structural obstruction.
2Reliability
If traditional bike carriers are used, then they can hold bicycles, but they cannot stably hold heavier e-bikes against inertia forces during sudden vehicle movements
Solution Approach 1:
The patent applies preliminary anti-action by using the rotatable arm member to proactively counteract inertia forces before they cause instability. During sudden vehicle movements, the arm member can be positioned to resist forward tilting and backward shifting of heavy e-bikes, providing preemptive stabilization that addresses the reliability issue with weighted vehicles.
3Ease of operation
If the arm member is positioned to hold the bike securely, then the bike is stable, but the arm member blocks the loading path of the bike
Solution Approach 1:
The patent resolves this contradiction through dynamic positioning of the arm member. During loading, the arm member rotates to a first position parallel to the reception elements, clearing the loading path. Once loading is complete, it rotates to a second position perpendicular to the reception elements to provide secure holding. This temporal separation of functions eliminates the blocking issue while maintaining stability.
4Adaptability or versatility
If a fixed arm position is used, then the structure is simple, but the arm cannot adapt to both loading and holding functions efficiently
Solution Approach 1:
The patent applies universality by designing the arm member to perform multiple functions through rotation. The same arm member serves both as a loading aid (when parallel to reception elements) and as a holding structure (when perpendicular to reception elements). This multi-functionality increases adaptability while keeping the rotational mechanism relatively simple.

AI summary
A carrier device (10, 40) mountable to a first vehicle (20) for holding a second vehicle (30), different from the first vehicle, is provided. The carrier device includes a supporting member (12, 42) having reception elements (122, 422) for supporting the second vehicle and an arm member (11, 41) coupled to the supporting member and located between the reception elements. The arm member further includes a carrier element (113, 413) configured to hold the second vehicle, a first rotation element (112, 412) coupled to the carrier element to rotate the carrier element along a first rotation axis, a first locking element (115, 4151) configured to control whether the first rotation element is allowed to rotate the carrier element along the first rotation axis, and a column element (111, 411) coupled to the first rotation element and a pivot control element (123, 423), perpendicular to the first rotation axis of the supporting member to be pivotably rotatable about the pivot control element, allowing the arm member to rotate.
