Bicycle Power Source Holder Lateral Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power source holders for bicycles are vulnerable to damage when the bicycle topples over or experiences lateral impacts, as they are typically fixed to the frame without the ability to move, leading to direct absorption of forces that can cause damage to the power source.
Innovation Solution
A power source holder design that incorporates a movable holder main body part attached to the bicycle frame via a frame attaching part with elongated holes, allowing the holder to move laterally and absorb impacts, thereby reducing the force applied to the power source. This design includes a locking mechanism to secure the power source and prevent theft, with the option for detachable or non-detachable retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power source is fixed rigidly to the bicycle frame, then the power source holder is stable and secure, but the power source is vulnerable to damage when the bicycle topples over or experiences lateral impacts
Solution Approach 1:
The frame attaching part is designed to be movable in the lateral direction, allowing the holder main body part to move dynamically when subjected to lateral impacts. This dynamic capability enables the power source holder to absorb impact forces by moving laterally rather than rigidly resisting them, thereby reducing damage to the power source while maintaining secure attachment during normal use
Solution Approach 2:
The fixing member is configured to change its fixed state to a movable state when subjected to lateral forces exceeding a predetermined threshold. Under normal conditions, the fixing member maintains a secure fixed connection; however, when lateral impact exceeds the threshold, the fixing member allows lateral movement, transforming the connection parameter from rigid to flexible to protect the power source
2Object-affected harmful factors
If the holder main body part is made movable in the lateral direction, then the impact on the power source is reduced, but the attachment stability may be compromised
Solution Approach 1:
The fixing member transitions between two states: a fixed state under normal conditions that provides stable attachment, and a movable state when lateral forces exceed a predetermined threshold. This parameter change allows the system to maintain stability during normal use while enabling movement for impact protection
Solution Approach 2:
The frame attaching part incorporates dynamic characteristics by being designed to move laterally when subjected to forces exceeding a predetermined threshold. This dynamic behavior allows the system to adapt its stability characteristics - maintaining firm attachment during normal use while allowing controlled movement during impacts to protect the power source

AI summary
A bicycle power source holder is provided that basically has a holder main body part and a frame attaching part. The holder main body part is configured to retain a power source. The frame attaching part is configured to movably mount the holder main body part to a bicycle frame so that the holder main body part is movably mounted in a lateral direction of a bicycle.
