Elastic Hitting Bicycle Bell for Urgent One-Touch Ringing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle bells require a fingertip operation to separate the striker or hitting element, making it difficult to ring the bell urgently.
Innovation Solution
A bicycle bell design that allows easy ringing by lightly hitting a plate or case body hitting member, which is elastically supported by the bell main body or attaching tool, enabling operation without prior fingertip positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hammer-like striker or spherical hitting element is used, then the bell can be rung, but it requires fingertip operation to separate the striker from the bell main body, making it difficult to ring urgently
Solution Approach 1:
The hitting member is designed to automatically return to its initial position after being struck by the user's hand. The elastic support member pushes the hitting member back to its original position after deformation, enabling the bell to be rung repeatedly without manual intervention to reset the striker. This self-resetting mechanism eliminates the time loss associated with positioning the fingertip for each strike.
Solution Approach 2:
The hitting member transitions from a static position to a dynamic state during operation. When the user's hand strikes the hitting member, it deforms and moves toward the bell main body, then automatically returns to its initial position due to the elastic support. This dynamic behavior allows rapid repeated ringing without manual resetting, resolving the time loss issue.
2Ease of operation
If a traditional striker mechanism is used, then the bell can ring, but the operation becomes complex requiring precise fingertip positioning
Solution Approach 1:
The invention extracts the complex fingertip positioning requirement from the operation process. Instead of requiring the user to precisely position their fingertip to activate a striker mechanism, the user simply needs to strike the hitting member with their hand in a natural motion. The elastic support mechanism handles the complex resetting action automatically, separating the simple user action from the complex mechanical response.
Solution Approach 2:
The mechanism performs its own resetting function automatically through the elastic support member, which pushes the hitting member back to its initial position after each strike. This self-service capability eliminates the need for complex manual manipulation and precise fingertip positioning, greatly simplifying the operation while maintaining the bell-ringing function.
3Productivity
If the hitting member is fixed rigidly, then the structure is simple, but it cannot return to initial position after being hit, preventing repeated ringing
Solution Approach 1:
The hitting member is designed with dynamic characteristics through the elastic support member, allowing it to deform and move when struck by the user's hand. After the strike, the elastic support automatically returns the hitting member to its initial position, enabling rapid repeated ringing. This dynamic design resolves the contradiction by introducing minimal complexity (the elastic support) to achieve high productivity (repeated ringing capability).
Solution Approach 2:
The elastic support member changes the physical state of the hitting member from a fixed rigid structure to a deformable dynamic structure. This parameter change allows the hitting member to move and return to its initial position after being struck, enabling repeated ringing operations while adding only the necessary elastic support component to the system.
