Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional operation button or lever is used for lock releasing, then the lock can be released, but the button/lever projects from the camera body surface making it obstructive and difficult to hold
Solution Approach 1:
The invention transitions from a protruding button/lever operation to a ring-shaped operation that functions on the surface plane of the camera body. The ring can be rotated or pressed in-plane, eliminating the need for projection and allowing the operation to be performed without obstructing the camera's profile.
Solution Approach 2:
The lock releasing mechanism is implemented as a ring-shaped structure that can be operated by rotating or pressing the ring in-plane. This curved, continuous shape allows for intuitive operation while maintaining a flush profile with the camera body surface, solving both the operability and design simplicity requirements.
2Ease of operation
If a pinpoint-like operation button is used, then the lock can be released, but the operation becomes difficult from certain hand positions and requires precise positioning
Solution Approach 1:
The operation is transformed from a pinpoint action requiring precise positioning to an in-plane ring operation that can be performed from various hand positions. The ring's rotational and pressing capabilities provide multiple operational dimensions, making it adaptable to different user hand orientations and positions.
Solution Approach 2:
The ring-shaped structure serves multiple operational functions (rotation, pressing, and combination movements) that can be executed from different hand positions. This multi-functionality ensures that users can operate the lock releasing mechanism regardless of their specific hand orientation or position when holding the camera.
3Ease of operation
If a projecting operation button is used, then the lock can be released, but it becomes an obstructive existence and reduces design freedom
Solution Approach 1:
The operation mechanism is repositioned from a protruding three-dimensional element to an in-plane two-dimensional ring structure. This dimensional change eliminates the obstructive projection while maintaining operational functionality, thereby simplifying the camera body's overall design and improving aesthetic appearance.
Solution Approach 2:
The lock releasing ring is merged with the camera body surface, integrating the operation mechanism into the existing design rather than adding a separate protruding element. This merging approach reduces design complexity and maintains a clean, simple profile while preserving the lock releasing function.
