Bicycle Frame Storage Latch for Aerodynamic Internal Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycles lack efficient internal storage solutions that maintain a sleek and aerodynamic design while accommodating cables and providing easy access to the storage compartment.
Innovation Solution
A bicycle frame storage system that utilizes the interior of a hollow tube for storage, featuring a cover secured by a latch that remains coupled to the tube during access, ensuring a flush exterior surface and allowing cables to be routed within the tube using a cable retainer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cover and latch system are added to access internal storage, then storage accessibility is improved, but device complexity increases
Solution Approach 1:
The latch system is divided into separate functional components: a cover member that provides access and a latch member that secures the cover. This segmentation allows each component to be optimized independently and simplifies the overall system by distributing functions across multiple simple parts rather than one complex mechanism.
Solution Approach 2:
The latch member is configured to be manually operable by the user without requiring additional tools or complex mechanisms. The system serves itself through direct user interaction with the latch, eliminating the need for electric motors, electronic controls, or other complex actuation systems.
2Ease of operation
If cable retainers and pouches are integrated into the frame, then cable management is improved, but device complexity increases
Solution Approach 1:
The cable retainer and tube pouch are nested within the hollow interior of the frame tube. This nesting arrangement allows cable management components to be housed within the existing frame structure without adding external complexity, as the frame's hollow interior serves as the containing space for these organizational elements.
Solution Approach 2:
The hollow interior of the frame tube serves multiple functions: it provides structural support as part of the frame, acts as a conduit for cables, and serves as storage space for the cable retainer and tube pouch. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall device complexity.
3Adaptability or versatility
If internal storage is accessed through the frame tube, then storage utility is improved, but aerodynamic design is compromised
Solution Approach 1:
The access opening is extracted from the continuous surface of the frame tube and positioned in a location that minimizes impact on aerodynamic performance. The opening is taken out of the main aerodynamic flow path, allowing the frame to maintain its sleek profile while still providing access to internal storage.
Solution Approach 2:
The frame tube maintains its aerodynamic shape and smooth surface quality in the majority of its area, while a localized region contains the access opening. This local modification allows storage access without compromising the overall aerodynamic design, as the opening is confined to a small area that does not significantly disrupt airflow.

AI summary
A bicycle may include a frame, a cover and a latch. The frame may include a hollow tube having an interior and an access opening to the interior, wherein the cover closes the access opening. The latch is slidably coupled to the tube and releasably secures the cover to the tube. The latch is movable relative to the tub and the cover between a latched state and an unlatched state, wherein the latch remains coupled to the tube and is disconnected from the cover in the unlatched state.
