Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a case is designed to protect the electronic device from external impacts, then the protective function is improved, but the flexibility in supporting the device at various angles is reduced
Solution Approach 1:
The case incorporates a moving plate that can rotate relative to the base about a rotational axis, transitioning between a first state (parallel to the base) and a second state (inclined at an angle). This dynamic structure allows the case to adapt to different viewing ratios and support angles while maintaining protective functionality through its robust base and supporting members.
Solution Approach 2:
The case is divided into distinct functional components: a base with supporting surface, a movable plate with first and second supporting members, and a hinge system. This segmentation allows each component to perform its specific function - the base provides protection, the moving plate enables angle adjustment, and the hinge facilitates rotation - thereby resolving the contradiction between protection and flexibility.
2Strength
If a case provides protection from external impacts, then the structural strength is improved, but the device complexity increases
Solution Approach 1:
The base serves multiple functions: it provides protective strength against external impacts while also serving as the mounting structure for the hinge and rotational mechanism. The moving plate similarly provides both structural support and the rotational movement capability. This multi-functionality reduces overall case complexity by eliminating the need for separate protective and mechanical components.
Solution Approach 2:
The protective base and the rotational support structure are merged into a single integrated unit, with the hinge directly attached to the base's second surface. The moving plate combines both supporting members (first and second) into one component that performs both structural support and angle adjustment functions, thereby reducing device complexity while maintaining strength.
3Adaptability or versatility
If a case uses a movable and rotatable moving plate with thicker second supporting member, then the adaptability for various angles is improved, but the manufacturing complexity increases
Solution Approach 1:
The second supporting member is designed with greater thickness than the first supporting member, concentrating the structural reinforcement only where needed for the inclined support function. This localized quality enhancement achieves the required adaptability for various angles without requiring the entire case to be manufactured with higher complexity, as only specific regions (the thicker second supporting member) require special attention.

AI summary
A case coupled to an electronic device incudes a base including a supporting surface, a moving plate including a first supporting member and a second supporting member thicker than the first supporting member and movable on the second surface of the base with respect to the base, wherein a state of the moving plate includes a first state and a second state, wherein a side surface of the second supporting member and the supporting surface inclined with respect to the rotational axis faces each other within the first state, and faces the inner surface of the first supporting member or a side surface of the first supporting member perpendicular to the inner surface of the first supporting member, by a movement of the second supporting member with respect to the first supporting member within the second state.
