Portable Terminal Protector with Integrated Engagement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protectors for portable information terminals, such as smartphones and tablets, either impair the appearance and increase volume due to the need for hooks or buttons to secure the case body and protection cover, or compromise protection by not fully enclosing the device.
Innovation Solution
A protector design that engages the rear and front surfaces of the terminal without additional mechanisms, using rear and front engagement portions that lock together, reducing volume and maintaining a sleek appearance, with optional features like lock protrusions and grooves, and a card container on the rear protector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hooks or buttons are used to secure the case body and protection cover, then the protective function is improved, but the appearance is impaired and volume increases
Solution Approach 1:
The patent integrates the engagement mechanism directly into the case body structure by forming engagement protrusions and grooves as integral parts of the case components. This merging of the fastening function into the case structure itself eliminates the need for separate hooks or buttons, thereby maintaining protective reliability while reducing overall volume and improving appearance.
Solution Approach 2:
The patent extracts the engagement mechanism from being a separate附加 component (like hooks or buttons) and embeds it within the case body structure. The engagement protrusions and grooves are formed directly on the case components, separating the fastening function from the protective cover structure and integrating it into the case body, thus reducing volume while maintaining function.
2Reliability
If hooks or buttons are used to secure the case body and protection cover, then the protective function is improved, but the appearance is impaired
Solution Approach 1:
The engagement mechanism is merged with the case body structure, where engagement protrusions and grooves are formed as integral features of the case components rather than separate attachments. This integration eliminates visible external fastening elements, preserving the sleek appearance while ensuring reliable protective function through the embedded engagement system.
3Reliability
If a comprehensive protective case is designed to cover all surfaces, then protection is improved, but volume and complexity increase
Solution Approach 1:
The protective case is segmented into distinct functional components: a case body with engagement protrusions and a protective cover with corresponding engagement grooves. This segmentation allows each component to be optimized for its specific function while the engagement features provide a simple coupling mechanism, reducing overall structural complexity compared to fully integrated designs.
Solution Approach 2:
The case body and protective cover are designed with multi-functionality: the case body provides structural support and houses engagement protrusions, while the protective cover offers surface protection and receives engagement grooves. The engagement features serve dual purposes of both fastening and alignment, reducing the need for separate alignment mechanisms and simplifying the overall structure.
