Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional joystick design is used, then the structure is simple and manufacturing is easy, but the appearance is monotonous and fashion sense is reduced
Solution Approach 1:
The patent applies color changes by incorporating a light guide structure with multiple light guide parts that have different transmittances, allowing the joystick to display different colors and lighting effects. The light guide parts can be configured to emit different colors of light, transforming the单调 appearance into a visually appealing design with various color combinations and lighting patterns.
Solution Approach 2:
The patent adds another dimension by introducing light as a new element to the joystick design. The light guide structure creates a three-dimensional lighting effect within the joystick body, adding depth and visual interest beyond the traditional two-dimensional surface appearance. This dimensional addition enhances the fashion sense without significantly complicating the overall structure.
2Measurement precision
If a conventional joystick design is used, then the device is simple to operate, but visibility in low-light environments is poor leading to reduced user accuracy
Solution Approach 1:
The patent uses the light guide structure as an intermediary element between the light source and the user. The light guide parts with different transmittances act as mediators that control and distribute light to improve visibility of the joystick in low-light environments. This intermediary structure enhances user accuracy by making the joystick more visible without directly exposing the light source.
Solution Approach 2:
The patent applies local quality by configuring different light guide parts with different transmittances in specific locations. Certain areas of the joystick receive more light than others, creating localized illumination that highlights important operational areas. This selective lighting improves visibility and user accuracy by drawing attention to critical parts of the joystick interface.
3Adaptability or versatility
If light guide parts with different transmittances are used, then customizable lighting effects are achieved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the light guide structure into multiple light guide parts with different transmittances. Each segment can be independently configured to achieve different lighting effects, allowing for high adaptability and versatility. The segmented structure enables customizable lighting patterns while keeping each individual part relatively simple in design.
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
Enhances user accuracy and reduces erroneous operations by providing visible light output from specific sites on the joystick, allowing for customizable lighting effects and minimizing eye strain through adjustable brightness.
Implementation Method 1
The light source emits a light beam. The light beam is guided by the light guide structure. Consequently, the light beam is outputted from a specified site of the joystick module.
Implementation Method 2
The light guide structure includes a first light guide part and a second light guide part with different transmittances.
Data Source
AI summary
A joystick module includes a main body, a light guide structure and a light source. The main body includes at least one hollow region. The light guide structure is disposed within the main body. The light guide structure includes a first light guide part and a second light guide part with different transmittances. The first light guide part has a light output surface exposed outside the hollow region. The second light guide part has a light input surface. The light source is disposed within the main body and located beside the light input surface of the second light guide part. After the light source emits a light beam, the light beam is introduced into the light guide structure through the light input surface of the second light guide part and exited from the at least one light output surface of the first light guide part.
