Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cover is made with flat surfaces and sharp corners to simplify manufacturing, then manufacturing precision is improved, but aerodynamic and fluid dynamic properties deteriorate, causing detachment or damage during high-speed impacts
Solution Approach 1:
The patent applies curvature to the cover design by replacing flat surfaces with curved surfaces and sharp corners with rounded corners. This aerodynamic shaping reduces fluid dynamic stresses during high-speed impacts, preventing cover detachment or damage while maintaining manufacturing feasibility through standard molding techniques.
2Object-generated harmful factors
If rounded corners are added to the cover to improve safety, then object-generated harmful factors are reduced, but manufacturing precision deteriorates due to increased complexity
Solution Approach 1:
The patent implements rounded corners throughout the cover design, eliminating sharp edges that could cause injury during impact. These curved transitions are integrated into the overall aerodynamic shape, allowing standard plastic molding processes to manufacture the complex geometry without sacrificing safety or requiring excessive manufacturing precision.
3Adaptability or versatility
If electronic devices are disposed outside the cover to improve adaptability, then device versatility is improved, but device complexity increases and safety deteriorates due to increased vulnerability to impact
Solution Approach 1:
The patent integrates electronic devices (GPS, compass, accelerometer, wireless communication modules) inside the camera body rather than mounting them externally. This consolidation reduces the overall device complexity by eliminating separate mounting structures and connection means, while simultaneously improving safety by protecting these vulnerable components within the impact-resistant camera housing.
Solution Approach 2:
The camera body is designed as a multi-functional platform that integrates not only the optical unit but also various electronic devices (navigation, communication, sensing) within a single unified structure. This universal design allows the camera to perform multiple functions while maintaining a compact, aerodynamic form factor without external attachments.
4Reliability
If the cover is tightly fitted to the camera body to improve reliability, then strength is improved, but ease of operation deteriorates due to difficulty in removing and reattaching the cover
Solution Approach 1:
The patent divides the camera system into separable modules: the cover assembly can be removed and reattached independently from the base support. This segmentation allows the cover to be securely fitted during operation for reliability, while enabling easy removal for cleaning, maintenance, or accessory attachment, thus resolving the contradiction between secure fit and ease of operation.

AI summary
An action camera having a camera body joined to the cover, at least one optical unit disposed inside the cavity of the cover, and connection means used to connect the cover to the base support in such manner that the cover rotates with respect to the base support around an axis. The cover being a cap shaped as a portion of geoid cut at a parallel of 50°-60° in such a manner that the cap has a basically flat upper surface and a lateral surface that is curved.
