Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing puncture detection tools for bicycles are limited by the need to be used horizontally, static clumping of floatation elements, and difficulty in accurately reading the movement of detection elements, which hinders effective puncture location and repair.
Innovation Solution
A portable, lightweight apparatus comprising elongate portions with a clamping mechanism and detection elements mounted on axles within a housing, allowing for vertical use and clear visualization of puncture location through rotating detection elements aligned with air flow, facilitating easy identification and repair of puncture holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polystyrene balls are used as floatation elements, then the detector can identify puncture holes through ball movement, but the balls clump together due to static charge and do not activate effectively
Solution Approach 1:
The patent replaces polystyrene balls with lightweight plastic balls that are cheaper and less prone to static charge accumulation. These balls are designed to be simple, inexpensive components that can be easily replaced if needed, solving the clumping issue while maintaining detection functionality.
Solution Approach 2:
The patent changes the material parameter of the floatation elements from polystyrene to lightweight plastic, altering the static charge properties and weight characteristics to eliminate clumping while maintaining adequate responsiveness to air flow for reliable puncture detection.
2Ease of operation
If the detector is used vertically, then portability and ease of carrying is improved, but the floatation elements cannot properly indicate puncture location due to gravity affecting their movement
Solution Approach 1:
The patent uses lightweight plastic balls with weight significantly reduced compared to traditional floatation elements. This weight reduction counteracts the effect of gravity when used vertically, allowing the balls to still respond adequately to air flow pressure changes while enabling the detector to be held in vertical or angled positions for improved portability.
Solution Approach 2:
The patent designs the detection system to be dynamically adaptable to different orientations. The lightweight balls can move freely in response to air flow regardless of the detector's orientation, whether horizontal, vertical, or at an angle, making the device versatile and easy to use in various positions during cycling.
3Object-generated harmful factors
If plastic balls are used instead of polystyrene balls, then static charge clumping is reduced, but the balls are too heavy for the limited air flow to provide suitable readings
Solution Approach 1:
The patent specifies lightweight plastic balls that are inexpensive and simple in design, optimizing them to be as light as possible while maintaining adequate responsiveness. These simple, cheap components are designed to work effectively with the limited air flow available in puncture detection applications.
Solution Approach 2:
The patent carefully selects plastic materials and ball dimensions to achieve optimal weight characteristics. The balls are made sufficiently lightweight to respond to limited air flow from punctures, while being heavy enough to minimize static charge effects, finding the optimal balance between these competing requirements.
4Reliability
If traditional floatation elements are used, then puncture detection is possible, but accurately seeing and reading the movement of the balls is difficult or erroneous
Solution Approach 1:
The patent incorporates visual enhancement features on the plastic balls, such as contrasting colors or patterns, that make their movement more easily visible and readable. This allows cyclists to quickly and accurately identify puncture locations without difficulty, improving the overall usability and reliability of the detection system.

AI summary
An apparatus (301) for detecting a puncture comprises a housing (302) comprising a plurality of compartments (501). Each compartment comprises an opening (701) for receiving a flow of air into the compartment. Each compartment also comprises a detection element (401) mounted on an axle (403), the axle having a first end (404) and a second end (405) and being secured at said first end and said second end within the compartment. The detection element is rotatable about the axle and when a flow of air passes through the opening into the compartment, the detection element rotates around the axle in response to the flow of air.
