Rotational Bicycle Access Carrier With Cantilever Tines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detachable accessory carriers for bicycles fail to efficiently reduce user burden and protect accessories from damage while allowing easy attachment and detachment, as they often require complex installations and do not provide adequate protection or flexibility in securing various sizes and types of items.
Innovation Solution
A detachable accessory carrier with an extension beam and means for removable engagement to a bicycle seat post, featuring a slidable and rotatable design with cantilever flexible tines and a variable slot area, allowing for secure retention and easy release of accessories through a combination of rotational engagement and stair step configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a detachable accessory carrier is designed with complex installation mechanisms to improve security and protection of accessories, then the reliability and protection of accessories are improved, but the ease of operation and simplicity of attachment/detachment deteriorate
Solution Approach 1:
The accessory carrier is divided into separate modular components: a base structure that attaches to the bicycle frame, and detachable accessory holders that can be independently attached and removed. This segmentation allows the main carrier to remain securely installed while accessories can be easily added or removed without affecting the overall installation.
Solution Approach 2:
The accessory carrier incorporates dynamic elements such as movable clamps, adjustable straps, and spring-loaded retention mechanisms that automatically engage and disengage. These dynamic features provide secure holding when engaged but allow quick release when needed, resolving the contradiction between security and ease of operation.
2Adaptability or versatility
If the accessory carrier is designed to accommodate various sizes and types of items to improve adaptability, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The accessory carrier employs universal attachment mechanisms such as standardized mounting brackets, adjustable-length straps, and multi-position clamps that can secure diverse items including water bottles, helmets, and fishing rods. These universal features allow a single carrier design to handle multiple accessory types without requiring separate specialized holders for each item type.
Solution Approach 2:
The carrier design incorporates nested or telescoping elements where smaller accessory holders can be placed within or attached to the main carrier structure. This nesting approach allows multiple accessories of different sizes to be accommodated in a hierarchical arrangement, maintaining versatility while avoiding the need for completely separate attachment systems for each accessory type.
3Ease of operation
If the accessory carrier uses simple attachment mechanisms to improve ease of operation, then the ease of attachment and detachment is improved, but the reliability and security of accessory retention deteriorates
Solution Approach 1:
The accessory carrier incorporates self-latching mechanisms, automatic engagement clips, and spring-loaded retention systems that secure accessories without requiring complex manual operations. These self-service features automatically engage when accessories are placed in the carrier and provide reliable retention through mechanical interlocking, eliminating the need for complex fastening procedures while maintaining security.
4Adaptability or versatility
If the accessory carrier is designed with multiple components to improve adaptability and security, then the versatility and protection are improved, but the device complexity and difficulty of manufacture increase
Solution Approach 1:
The accessory carrier is designed as separate modular components that can be manufactured independently using standardized processes and materials. The base carrier, accessory holders, and attachment mechanisms are produced as discrete parts that are subsequently assembled, allowing each component to be optimized for its specific manufacturing requirements and simplifying production compared to creating a single complex integrated structure.
