Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If projection equipment is integrated into wearable items with fixed structure, then the device can be worn comfortably, but the projection direction is fixed and application scenarios are limited
Solution Approach 1:
The patent applies the dynamics principle by making the projection device rotatable relative to the wearable carrier. The projection device is mounted on a rotatable mechanism that allows it to change its projection direction dynamically, transforming from a fixed structure to a movable one. This enables the same wearable device to project images in multiple directions (forward, backward, left, right) without requiring multiple separate devices, thus improving adaptability while controlling complexity through a single integrated rotatable mechanism.
2Adaptability or versatility
If multiple projection devices are provided to enable multi-directional projection, then application scenarios become more extensive, but the device complexity and size increase
Solution Approach 1:
The patent applies the universality principle by designing a single wearable projection device that can perform multiple functions - projecting images in different directions. Instead of providing separate projection devices for each direction (which would increase volume), the invention creates one universal projection device that can be oriented in multiple directions through the rotatable mechanism. This single device serves the function of what would otherwise require multiple dedicated devices, thereby maintaining compact size while achieving multi-directional projection capability.
3Adaptability or versatility
If a rotatable structure is added to change projection direction, then application scenarios increase, but the ease of operation decreases due to additional control mechanisms
Solution Approach 1:
The patent applies the self-service principle by enabling the projection device to automatically adjust its projection direction based on detected touch positions. When a user touches a specific area on the wearable device, the system automatically rotates the projection device to the appropriate orientation and projects the image accordingly, without requiring manual adjustment of mechanical components. This automated response simplifies operation while maintaining the ability to project in multiple directions, as the system serves itself by automatically orienting the projection based on user input.
