Double Bearing Reel Indication Portion for Tangling Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double bearing reels face issues with determining the releasable state of the opening/closing mechanism, leading to potential tangling of the fishing line and uncomfortable grip feelings during fishing, due to the exposure of operation members on the side surfaces.
Innovation Solution
Incorporating an indication portion that visually and haptically indicates the releasable state of the opening/closing mechanism, ensuring accurate determination and preventing the operation member from being exposed on the side surfaces, thus avoiding tangling and discomfort during fishing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation member is exposed on the side surface of the cover plate, then the opening/closing mechanism can be operated, but the fishing line may become tangled around the operation member
Solution Approach 1:
The harmful function (exposure of operation member causing line tangling) is extracted from the system by positioning the operation member inside the cover plate rather than on the outer surface, eliminating the source of the problem while preserving the essential operation function
2Ease of operation
If the operation member is exposed on the side surface of the cover plate, then the opening/closing mechanism can be operated, but the grip feeling becomes uncomfortable during fishing
Solution Approach 1:
The operation member is extracted from the outer surface and repositioned inside the cover plate, removing the source of discomfort during gripping while maintaining operational accessibility through the opening portion
3Object-affected harmful factors
If the operation member is not exposed on the side surface, then the grip feeling remains comfortable, but it becomes difficult to determine the releasable state of the opening/closing mechanism
Solution Approach 1:
An indication portion is introduced as an intermediary element that visually communicates the operational state (releasable or locked) of the opening/closing mechanism without requiring the operation member to be exposed on the outer surface
Solution Approach 2:
The indication portion utilizes visual differentiation (such as color changes or positional visibility changes) to clearly indicate whether the opening/closing mechanism is in a releasable or locked state, enabling easy detection without exposing the operation member
4Object-affected harmful factors
If the operation member is positioned inside the cover plate, then the fishing line ta n gling and grip discomfort are prevented, but the operation member becomes less accessible
Solution Approach 1:
The cover plate is segmented with an opening portion that provides access to the operation member while keeping it positioned inside the cover plate body, balancing protection and accessibility

AI summary
One object is to provide a double bearing reel capable of visually and accurately determining a releasable state of an opening/closing mechanism for releasing a frame by cover plates, the opening/closing mechanism being prevented from causing tangling of a fishing line. The double bearing reel has an opening/closing mechanism for enabling a cover plate on an opposite side to a handle to be opened/closed with respect to a frame. Said opening/closing mechanism includes an operation member for switching between a releasable state where the frame is releasable by the cover plate and a closed locked state where the frame is closed by the cover plate and an indication portion for indicating the releasable state. In tandem with a switching operation, the indication portion is exposed outside of a side plate in the releasable state and retracted inside of the side plate in the closed locked state.
