Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sports competitions using a shuriken, the throwing method where a shuriken is placed on one palm and sent forward by the other palm lacks a sense of reality and authenticity.
Innovation Solution
A game device with a housing that includes a light source, optical mechanism, and movement detection sensor to simulate the throwing experience by projecting light in the direction of the operator's second palm, allowing players to experience a simulated shuriken throw with improved presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a shuriken is placed on one palm and sent forward by the other palm, then the throwing method is simple and easy to operate, but the sense of reality and authenticity is poor
Solution Approach 1:
The patent uses a light source to create a virtual copy of the shuriken's flight path. The light emitted from the housing follows the trajectory that a real shuriken would take, allowing players to see a visual representation of the throw without needing to physically throw a real shuriken. This copying approach maintains simplicity while enhancing realism.
Solution Approach 2:
The light source acts as an intermediary between the player's hand movement and the perceived shuriken flight. Instead of directly throwing a real shuriken, the player's palm movement triggers light emission that mediates the experience, bridging the gap between simple hand motion and realistic shuriken throwing sensation.
2Reliability
If a light source is used to simulate shuriken throwing, then the sense of presence is improved, but the device complexity increases
Solution Approach 1:
The housing serves multiple functions: it holds the light source, acts as the emission point for the light, and provides structural support. By making the housing multi-functional, the patent avoids adding separate components that would increase complexity, while still achieving the goal of improved presence through light emission.
Solution Approach 2:
The patent combines the light source, optical mechanism, and housing into a single integrated unit. Rather than having separate components for light generation, light projection, and structural support, these elements are merged into one device that can be held in the palm, minimizing complexity while maximizing the sense of presence.
3Measurement precision
If a movement detection sensor is added to detect palm movement, then the light projection accuracy is improved, but the device complexity increases
Solution Approach 1:
The movement detection sensor enables the system to automatically detect and respond to the player's hand movements without requiring external input or complex control mechanisms. The sensor self-services by converting physical palm movement directly into light projection commands, improving accuracy while keeping the control system simple.
Solution Approach 2:
The patent replaces complex mechanical throwing mechanisms with a sensor-based detection system. Instead of using mechanical components to track and replicate shuriken trajectories, an electrostatic capacitance sensor electronically detects palm movement, substituting a simple electronic system for what would otherwise require complex mechanical engineering.
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 game device provides a realistic simulation of shuriken throwing by projecting light in the direction of the operator's second palm, enhancing the sense of presence and allowing players to determine if the projected light hits a target, thus improving the throwing experience.
Implementation Method 1
the movement detection sensor may be an electrostatic capacitance sensor provided on the upper surface. The forward movement of the second palm on the upper surface can be detected based on the change in capacitance according to the distance from the second palm.
Implementation Method 2
a light source that is housed in the housing and configured to emit light; an optical mechanism that is housed in the housing and projects the light from the light source forward from a tip of the front protruding portion
Data Source
AI summary
To achieve a pseudo experience of launching a shuriken with improved presence feeling. A game device includes: a housing; a light source; an optical mechanism; a movement detection sensor; and a light source driver. The housing is configured to be held on a first palm of an operator. The housing includes a front protruding portion which protrudes forward and an upper surface which faces upward. The light source is housed in the housing and configured to emit light. The optical mechanism is housed in the housing and projects the light from the light source forward from a tip of the front protruding portion. The movement detection sensor detects forward movement of a second palm of the operator on the upper surface, wherein the second palm is different from the first palm. The light source driver drives the light source based on movement detection by the movement detection sensor.
