Bicycle Frame Access Opening for Built-In Damper Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double suspension bicycles face difficulties in accessing built-in dampers for maintenance, adjustment, and cleaning due to their internal location within the frame tubes, necessitating disassembly, and they lack sufficient space for additional bottle holders.
Innovation Solution
A bicycle frame with a built-in damper that features an upper access opening and a removable cover, allowing easy access and protection, along with an integrated bottle holder attachment point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the damper is housed inside the frame tube to protect it from dirt, then the damper is protected from particles that impair effectiveness, but access for cleaning, adjustment, or maintenance becomes laborious and complex
Solution Approach 1:
The frame tube is segmented by creating an opening in the lower portion that can be independently accessed. The damper housing is divided into accessible and protected zones, allowing maintenance operations without exposing the entire damper to external contaminants.
Solution Approach 2:
A specialized access tool or mechanism is introduced as an intermediary to bridge the gap between the need for damper access and protection. This intermediary enables maintenance operations through the opening while maintaining the protective enclosure structure.
2Object-affected harmful factors
If the damper is housed inside the frame tube, then the damper does not get dirty, but disassembly of the frame and/or damper is necessary to remove it for maintenance
Solution Approach 1:
The frame structure is segmented by creating a removable section or opening in the lower portion of the frame tube. This segmentation allows the damper to be accessed and removed independently without disassembling the entire frame structure.
Solution Approach 2:
The frame tube transitions from a static enclosed structure to a dynamic structure with a removable or open section. This dynamic modification enables easy access to the damper while maintaining protection when the opening is closed.
3Reliability
If the damper is attached to the upper tube or lower tube, then damping function is provided, but space for bottle holders is limited to only the lower tube
Solution Approach 1:
The frame structure is designed with multi-functionality, where the lower tube opening serves dual purposes: providing access to the damper for maintenance and creating space for bottle holder installation. This increases versatility without compromising damping function.
Solution Approach 2:
The design utilizes the vertical dimension by positioning the opening in the lower portion of the frame tube, creating additional usable space in that region for bottle holders while maintaining the damping function in the upper/central regions.

AI summary
The present invention relates to a bicycle frame with accessible built-in damping, having at least one damping element (2) internally built into a housing (3) provided for this purpose within the tubes that make up the frame (1), comprising: an opening (30) for access to the housing (3), having a shape and dimension such that they allow the removal and placement of the damper (2) or cleaning, adjustment and/or maintenance tasks without having to remove same; and a removable cover (4) that completely covers and closes said opening (30) for access to the housing (3) with the damper (2). Optionally, the cover (4) comprises means for attaching a bottle holder or container holder support (6).
