Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing remote operation systems for electric fishing reels, such as those described in JP 2005-218354 A and JP 2021-145672 A, require continuous button pressing or visual attention, making them difficult to use effectively.

Innovation Solution

A controller with a grip portion and an operation member, such as a rotating body, slide body, or swing body, allowing adjustment of the drive motor output by thumb operation without continuous pressing or visual attention, using a controller with a display device and operation members like a rotating dial, slide, or swing mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a button-type operation switch is used for remote operation, then the reel main body can be operated remotely, but continuous button pressing is required making remote operation difficult

Engineering Contradiction:

Improveremote operation easeVSAvoidcontinuous pressing time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The operation member is designed as a rotating body that can be operated by a single rotational motion of the thumb, transforming the static button-pressing action into a dynamic rotational operation. This allows the user to adjust motor output continuously during rotation without needing to repeatedly press buttons, thereby reducing the time and effort required for remote operation.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If a smartphone screen is used for operation, then the reel main body can be operated remotely, but visual attention is required making remote operation difficult

Engineering Contradiction:

Improveremote operation easeVSAvoidvisual attention requirement

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The electronic touchscreen interface is replaced with a mechanical operation member (rotating body, slide body, or swing body) that provides tactile feedback. This mechanical substitution eliminates the need for visual attention during operation, as the user can feel the position and movement of the operation member through touch alone, enabling remote operation without looking at a screen.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If multiple button presses are required for operation adjustment, then precise control is achieved, but operation complexity increases

Engineering Contradiction:

Improvemotor output control precisionVSAvoidoperation complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The operation member is designed to provide continuous adjustment capability through a single motion (rotation, sliding, or swinging). The motor output can be adjusted progressively during the single operation motion, eliminating the need for multiple discrete button presses. This preliminary action approach allows precise control to be achieved in one continuous motion rather than through multiple separate actions.

Inventive Principle:

Principle #10Preliminary action
