Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional simulation controller design is used, then device complexity is maintained, but ease of operation deteriorates for individuals with visual or motor skills impairments
Solution Approach 1:
The controller implements local quality by providing buttons with different tactile characteristics at specific locations. The first button has a first tactile characteristic while the second button has a second tactile characteristic different from the first, allowing users with visual impairments to distinguish buttons through touch alone, thereby improving ease of operation without adding overall device complexity.
Solution Approach 2:
The controller applies asymmetry by designing buttons with non-uniform tactile properties. Rather than all buttons having identical characteristics, the patent creates intentional asymmetry in button textures, shapes, or surface properties, enabling users to differentiate between buttons through tactile feedback, thus enhancing operability for impaired users.
2Adaptability or versatility
If traditional button design is used, then manufacturing simplicity is maintained, but accessibility for impaired users deteriorates
Solution Approach 1:
The patent applies local quality by implementing buttons with differentiated tactile characteristics at specific locations on the controller. This allows the device to adapt to diverse user needs, particularly for individuals with visual or motor skills impairments, while maintaining a relatively simple manufacturing process by only modifying specific button properties rather than the entire device structure.

AI summary
An accessibility computer game controller includes a central control button on a round base and peripheral control buttons on the base surrounding the central control button. The peripheral control buttons can have distinct sizes and shapes. An analog stick unit is reciprocatingly engaged with the base and includes a control portion rotatable relative to the base.
