Solution Overview

Problem

Existing fishing simulation apparatuses face challenges in simulating a realistic fishing experience due to limited fishing line length, tangling issues, and the need for manual rewinding after successful fishing, which detracts from the realism and convenience.

Innovation Solution

A fishing simulation apparatus with a fishing reel and main motor that allows for an infinite circulation of the fishing line, using pulleys and a belt to prevent tangling and enable seamless reeling, combined with a display unit for virtual reality experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the fishing line length is limited by fixing both ends to the fishing rod and motor, then the apparatus structure is simplified, but the realism during casting and reeling is insufficient and the fishing line may be easily entangled

Engineering Contradiction:
Improverealism during casting and reelingVSAvoidfishing line circulation structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

A guide pulley is introduced as an intermediary component between the fishing rod and the motor. The fishing line passes through this guide pulley, allowing it to move freely in both directions without being fixed at both ends. This intermediary element enables the fishing line to achieve infinite effective length while maintaining a relatively simple overall structure, resolving the contradiction between operational realism and structural complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the fishing line has limited length, then the apparatus structure is simpler, but the fishing line may be easily entangled during winding and unwinding

Engineering Contradiction:
Improvefishing line tangling preventionVSAvoidfishing line length
Core Design Contradiction:
ReliabilityVSLength of moving object

Solution Approach 1:

The fishing line is designed to be dynamically movable through the guide pulley system rather than being fixed at both ends. This dynamic configuration allows the fishing line to freely adjust its position and length during winding and unwinding operations, preventing entanglement while maintaining sufficient line length for realistic fishing operations.

Inventive Principle:
Principle #15Dynamics

3Loss of time

If a bobbin is provided at the motor to wind the fishing line, then the original setting can be restored after fishing, but the volume of the apparatus is increased

Engineering Contradiction:
Improverewinding waiting timeVSAvoidapparatus volume
Core Design Contradiction:
Loss of timeVSVolume of stationary object

Solution Approach 1:

The bobbin component is extracted from the motor assembly. Instead of providing a bobbin at the motor to wind the fishing line, the system uses the guide pulley configuration that allows the fishing line to be freely moved and reset without requiring a dedicated bobbin at the motor, thereby reducing apparatus volume while eliminating rewinding waiting time.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A fishing simulation apparatus include: a fishing reel which is mounted on a fishing rod and provided with a manual driving pulley for winding up a fishing line, and which moves the fishing line in opposite directions; and a main motor for pulling the connected fishing line from the fishing rod and the fishing reel, in which the fishing line is connected in an infinite circulation manner, sequentially passing through the fishing rod, the fishing reel, and the main motor.
