Luggage Carrier Adapter With Hook And Latch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage carrier systems for bicycles are cumbersome to attach and detach adapters, particularly due to the difficulty in aligning pegs or hooks under a basket or bag, leading to instability and ease of use issues.
Innovation Solution
An adapter with a hook-shaped portion and a latch mechanism, combined with a counterhold for stability, allows for easy attachment and detachment by distributing connection forces evenly, ensuring secure and robust attachment to the luggage carrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional spring loaded clamp devices are used on horizontal bars, then items can be clamped to the luggage carrier, but the attachment process becomes complicated and time-consuming
Solution Approach 1:
The attachment system is divided into separate components: the luggage carrier with attachment members and the adapter with corresponding engagement features. This segmentation allows the adapter to be pre-assembled and then quickly attached to the carrier, reducing the complexity and time of the attachment process compared to traditional spring-loaded clamps that require manual adjustment and tightening.
Solution Approach 2:
The adapter is designed with pre-configured attachment members that are ready to engage with the luggage carrier. The counterhold feature is pre-positioned to automatically engage with the attachment members when the adapter is placed on the carrier, eliminating the need for manual alignment and adjustment during the attachment process.
2Ease of operation
If pegs protrude from four corners of the attachment device, then the device can be positioned on the carrier rack, but the pegs are not visible underneath the basket making it hard to align all four pegs to slots
Solution Approach 1:
The invention extracts the alignment function from a multi-point peg system and concentrates it into a single visible attachment member on the luggage carrier. This single attachment member serves as a clear visual and physical guide for positioning the adapter, eliminating the complexity of aligning four invisible pegs with four slots while still providing stable attachment through the counterhold mechanism.
3Stability of the object's composition
If multiple attachment members are distributed evenly on the luggage carrier, then the adapter gains stability when attached, but the structure becomes more complex
Solution Approach 1:
The attachment system is segmented into a simple support structure (the single attachment member on the carrier) and a stabilizing mechanism (the counterhold on the adapter). This segmentation allows the main support structure to remain simple while the stabilizing feature provides the necessary stability through its engagement with the attachment member, avoiding the need for multiple distributed attachment members.
4Stability of the object's composition
If a latch mechanism with counterhold is used to secure the adapter, then the adapter cannot move along the luggage rack providing additional stability, but the mechanism becomes more complex
Solution Approach 1:
The latch mechanism with counterhold is designed to automatically engage and secure the adapter to the luggage carrier without requiring additional user action. When the adapter is placed on the carrier, the counterhold automatically engages with the attachment member, providing longitudinal stability through self-latching action, thereby keeping the mechanism simple while achieving enhanced stability.
