Winch Keyhole Locking Housing With Elastic Protected Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exposed winch keyholes on bolts, such as those on sailing vessels, are prone to improper operation, leading to difficulties in disassembly and potential damage, as they lack effective protection mechanisms.
Innovation Solution
A security-locking device with a housing that fits over the winch keyhole, featuring elastic components and an operation key, which locks into place to prevent exposure and includes an adjusting mechanism to ensure the keyhole remains protected, and can be easily accessed when needed for disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the winch keyhole is exposed for easy access, then the ease of operation is improved, but the risk of improper operation and damage increases
Solution Approach 1:
The device segments the keyhole access into two states: protected (covered by housing) and accessible (housing removed or opened). This allows the keyhole to be either fully protected or fully accessible, eliminating the compromise of partial exposure that creates vulnerability to improper operation.
Solution Approach 2:
The housing acts as an intermediary between the keyhole and the external environment. It provides a controlled interface that protects the keyhole while allowing authorized access through designated mechanisms (removal or opening), thereby preventing direct exposure and improper operation.
2Object-affected harmful factors
If the security-locking device covers the winch keyhole completely, then the protection effect is improved, but the ease of operation deteriorates
Solution Approach 1:
The device transitions from a static covered state to an accessible state through dynamic mechanisms. The housing can be removed entirely or opened to expose the keyhole, allowing the system to adapt between maximum protection and maximum accessibility as needed, rather than being fixed in one state.
Solution Approach 2:
The housing is pre-positioned to cover and protect the keyhole before any operation is needed. When access is required, the housing is removed or opened in advance, ensuring the keyhole is fully accessible when the wrench needs to be applied, eliminating delays during critical operations.
3Object-affected harmful factors
If the housing is made larger to ensure complete coverage, then the protection effect is improved, but the device complexity and size increase
Solution Approach 1:
The housing is designed with specific local features (notches, engagement structures) that enable precise fitting over the keyhole without requiring excessive size. The engagement notches and lateral wall interactions provide localized engagement points that secure the housing effectively with minimal material and complexity.
Solution Approach 2:
The elastic component provides self-adjusting engagement with the housing and keyhole structure. The elastic portion automatically engages with the lateral wall and maintains proper positioning without requiring additional adjustment mechanisms, reducing overall device complexity while ensuring complete coverage.
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
The device effectively prevents improper operation and exposure of the winch keyhole, ensuring safety and facilitating secure disassembly by providing a stable engagement force and adjustable protection.
Implementation Method 1
the elastic portion of the elastic component exposed outside the housing is abutted against the lateral wall of the winch keyhole, so that the security-locking device is locked in the winch keyhole
Implementation Method 2
the user can use an operation key to engage with an engagement aperture of the housing, and use the operation key to drive the security-locking device to separate from the winch keyhole

AI summary
The disclosure relates to a security-locking device for a winch keyhole, including a housing, a main body and an elastic component. The housing includes an accommodation space, a top surface, a bottom surface, an engagement aperture and a notch. The engagement aperture is embedded in the top surface, the engagement aperture communicates with the accommodation space, the accommodation space passes through the bottom surface, and the notch is disposed between the top surface and the bottom surface. The main body is accommodated in the accommodation space, and includes a receiving seat. The elastic component is sandwiched between the housing and the main body, and includes a fixed portion and an elastic portion. The fixed portion is accommodated within the receiving seat, and the elastic portion is exposed outside the housing through the notch corresponding thereto. When the hosing is placed into the winch keyhole, the winch keyhole is not exposed.
