Bicycle Cargo Pack Carrier With Adjustable Pivoting Arms for Wheel Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo packs for bicycle handlebars face challenges in versatility, as they need to fit various bicycle configurations, avoid abrasion and noise from the front wheel, and maintain balance while accommodating varying volumes of contents.
Innovation Solution
A cargo pack carrier with adjustable and pivotable arms, a central spine, and locking mechanisms, allowing for versatile mounting and positioning on handlebars, along with a cargo container secured by straps and hooks, ensuring clearance from the wheel and control elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cargo pack is mounted on bicycle handlebars to be versatile for different bicycle configurations, then the adaptability is improved, but the device complexity increases due to adjustable and pivotable mechanisms
Solution Approach 1:
The cargo pack carrier employs adjustable arm spacing and pivotable support mechanisms that allow dynamic reconfiguration to fit different handlebar configurations. The arms can be adjusted in spacing along the handlebar, and the support can pivot to different angles, enabling the same device to adapt to various bicycle types and handlebar shapes.
Solution Approach 2:
The carrier design incorporates multiple adjustment capabilities (arm spacing adjustment, support pivoting) that enable a single device to serve multiple bicycle configurations and mounting positions, achieving universality across different bicycle types without requiring multiple specialized carriers.
2Reliability
If the cargo pack is positioned away from the front wheel to avoid abrasion and noise, then the reliability is improved, but the ease of operation worsens due to limited mounting positions
Solution Approach 1:
The pivotable support mechanism allows the cargo pack to be dynamically repositioned to optimal locations that maintain clearance from the front wheel while avoiding control elements. The support can pivot to angle adjustments that clear the wheel arch and accommodate different rider positions and control element locations.
3Stability of the object's composition
If the cargo pack is centralised on the handlebars to avoid imbalance, then the stability is improved, but the adaptability worsens when contents volume varies
Solution Approach 1:
The adjustable arm spacing and pivotable support create a dynamic mounting system that can be reconfigured to centralize the cargo pack on the handlebars regardless of content volume. When the pack is partially filled, the mounting position can be adjusted to maintain centralization and balance, whereas a fixed mounting would create imbalance.
4Adaptability or versatility
If the arms are made adjustable in spacing to fit different handlebars, then the adaptability is improved, but the device complexity increases due to additional connecting structures
Solution Approach 1:
The carrier is segmented into separate adjustable arms that can be independently positioned along the handlebar. Each arm has its own adjustment mechanism, allowing the spacing between arms to be customized for different handlebar widths and shapes, with each segment functioning semi-independently.

AI summary
A cargo pack for mounting on a handlebar 12 of a bicycle comprises a support in the form of a cage 20 which is connected to the handlebar 12 by arms 18. The arms 18 are securely fixed at openings 22 to the handlebar 12 in an adjustable manner, and the cage 20 is connected to the arms 18 by respective connecting structures 38 which enable adjustment of the spacing between the arms 18 in a direction parallel to the axis of the openings 22 and which enable pivoting of the support 20 relatively to 10 the arms 18 about the axis of the openings 22, the connecting structures 38 each having a locking mechanism for locking the support 20 with respect to the arms 18 in a selected pivoted position.
