Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underwater spotlights face challenges with clamping connections that are either irreversible or difficult to detach, complicating handling and maintenance.
Innovation Solution
A clamping connection utilizing an expanding body actuated via a threaded spindle, allowing for reliable and repeated release with a single actuating element, where swivel arms are pivotally connected with an internal thread for spreading or bringing together, and a nut for added stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a clamp connection with an expanding element is used, then the fastening strength is improved, but the ease of operation deteriorates because the connection becomes difficult to loosen
Solution Approach 1:
The clamp connection transitions from a static irreversible state to a dynamic reversible state. The spreading body can be actuated by the threaded spindle to expand the swivel arms for secure fastening, and then retracted by reversing the spindle rotation to release the clamping effect, enabling repeated attachment and detachment operations.
Solution Approach 2:
The traditional multi-screw mechanical fastening system is replaced with a single threaded spindle actuating a spreading body. This substitution simplifies the mechanical system from multiple sequential screw operations to a single rotational action that controls the expansion and retraction of the swivel arms, improving ease of operation.
2Reliability
If multiple fastening screws are used, then the reliability of connection is improved, but the device complexity increases and handling becomes more difficult
Solution Approach 1:
Multiple fastening screws are merged into a single integrated fastening system. The threaded spindle combines the functions of multiple fastening elements by actuating the spreading body, which simultaneously controls both swivel arms. This reduces the number of components and simplifies the fastening mechanism while maintaining reliable connection through the clamping effect.
Solution Approach 2:
The threaded spindle serves multiple functions: it acts as the actuating element, the fastening element, and the controlling mechanism for the spreading body. This single component performs what previously required multiple screws, reducing device complexity while maintaining connection reliability through its multi-functional design.
3Ease of operation
If a clamp connection is used instead of screw connections, then the ease of operation is improved, but the reliability of repeated release deteriorates
Solution Approach 1:
The clamp connection is designed with dynamic reversibility. The spreading body responds to the threaded spindle's rotation by expanding for secure attachment and retracting for reliable release. This dynamic behavior ensures that the connection can be repeatedly attached and detached with consistent reliability, overcoming the irreversibility issue of traditional clamp connections.
