One-Handed Adjustable Bottle Cage with Dynamic Girdle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable bottle cages require both hands to adjust the size for different water bottles, making it inconvenient for cyclists to use.
Innovation Solution
A bottle cage design featuring a cambered main body with two girdles and a regulating structure that allows for one-handed adjustment of the storage space size using a gear and operational unit, enabling easy placement and removal of water bottles of various sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional adjustable bottle cage with multiple insert holes is used, then it can accommodate different water bottle sizes, but it requires both hands to adjust the insert hole position, reducing ease of operation
Solution Approach 1:
The girdle is designed with dynamic adjustment capability through a slot-based mechanism. The bulge can move along the slot to different positions, allowing the storage space size to be dynamically changed according to different water bottle sizes. This dynamic structure replaces the static multiple-hole design, enabling continuous adjustment rather than discrete hole selection.
Solution Approach 2:
The adjustment mechanism is designed to be self-operating through a spring-loaded bulge system. When the bulge is pushed, it releases from one positioning point and snaps into the next position along the slot automatically, using spring force to assist the adjustment action. This self-service mechanism reduces the manual effort required and eliminates the need for two-handed operation.
2Adaptability or versatility
If the girdle storage space is made adjustable for different bottle sizes, then versatility is improved, but the device complexity increases due to multiple components needed for adjustment
Solution Approach 1:
The adjustment function is merged into the girdle structure itself. The bulge, slot, and spring components are integrated within the girdle, forming a compact adjustment mechanism that does not require separate external adjustment devices. This merging approach maintains versatility while controlling overall device complexity by incorporating the adjustment feature directly into the existing girdle component.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and easy adjustment of the storage space size to accommodate different water bottle sizes using only one hand, enhancing usability and convenience for cyclists.
Implementation Method 1
The gear engages with the first cage and the second cage, so that the gear brakes reverse actuation of the first girdle and the second girdle
Implementation Method 2
The operational unit is in contact with the gear, to brake the rotation of the gear

AI summary
A bottle cage applicable to water bottles of different sizes, which includes a main body, a first girdle, a second girdle and a regulating structure. Wherein the first girdle is opposite to the main body, a storage space is formed between the main body and the first girdle. One end of the first girdle leans against one side of the main body. The second girdle is adjacent to the first girdle. One end of the second girdle leans against the other side of the main body. The regulating structure brakes reverse actuation of the first girdle and the second girdle, the enclosure of the storage space is changed for placing the water bottles of different sizes. The water bottle can be placed and taken by operating the regulating structure with one hand, and the usability is high.
