Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation members (microphone, stick-like member) are integrally provided to the operation device, then various kinds of information can be input to the game machine main body, but the weight of the operation device increases and the light emitting member cannot be moved smoothly
Solution Approach 1:
The operation device is divided into a main body and detachable additional operation modules. The additional operation modules can be mounted or detached according to the type of operation to be performed, allowing the device to adapt to different input needs without permanently carrying unnecessary components that would increase weight.
Solution Approach 2:
The configuration of the operation device is made dynamic through the ability to attach and detach additional operation modules. This allows the device to change its functional composition based on the specific operation requirements, optimizing the weight-to-functionality ratio for each usage scenario.
2Measurement precision
If the distance between the camera and the light emitting member is recognized based on the size of the region of the imaged light emitting member, then distance information can be obtained, but false recognition occurs due to background brightness variations
Solution Approach 1:
The light emitting member emits light of a specific color (e.g., red) that is distinct from the background. The image processing unit detects this specific color to identify the light emitting member's position and size, making the measurement independent of background brightness variations and preventing false recognition.
Solution Approach 2:
A color filter or specific wavelength detection mechanism acts as an intermediary between the camera and the light emitting member. This intermediary selectively detects the light emitting member's color signal while filtering out background light, enabling accurate distance recognition regardless of background brightness.
3Ease of operation
If indicators are provided to distinguish between multiple operation devices, then users can identify their devices, but the indicators cause false detection when detecting the position of the operation device based on light from the light emitting member
Solution Approach 1:
Each operation device's light emitting member is assigned a unique identification color. The image processing unit detects both the position of the light emitting member and its color to simultaneously achieve accurate position detection and device identification, eliminating the need for separate indicators that would interfere with light-based detection.
Solution Approach 2:
The light emitting member serves multiple functions: it acts as both the light source for position detection and the identification indicator. This multi-functionality eliminates the need for separate indicator components and ensures that identification does not interfere with position detection accuracy.
4Adaptability or versatility
If additional operation modules are mounted to the main body, then various operation functions can be added, but the weight increases and smooth movement is hindered
Solution Approach 1:
The operation device is segmented into a lightweight main body and detachable additional operation modules. Users can attach only the modules needed for the current operation, keeping the overall weight low and movement smooth, while still having access to various functions when required.
Solution Approach 2:
The device configuration is dynamically adjusted by mounting or detaching additional operation modules based on the specific operation requirements. This dynamic configuration allows the device to maintain optimal weight-to-functionality ratio, ensuring smooth movement when full functionality is not needed.
