Flip Cover Coupling Structure for Camera Phone Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera phones lack adequate protection against external impacts, such as drops, due to insufficient absorption or dispersion of force, which can damage the display device and lens barrel, and suffer from weight imbalance between the front and rear sides, making them prone to damage and difficult to manufacture for portability.
Innovation Solution
A protective apparatus comprising a peripheral cover and a flip cover with a coupling structure that uses physical and chemical bonding between different materials to enhance rigidity, along with a sensing unit to control the display unit and a lens barrel cover for support, preventing damage from external impacts and improving usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lens barrel is added to the rear side of the camera phone, then the camera function is improved, but the weight balance between front and rear side deteriorates
Solution Approach 1:
The patent introduces a counterweight structure on the front side of the camera phone to balance the heavy lens barrel on the rear side. This counterweight compensates for the weight imbalance, making the device more comfortable to hold and use without sacrificing the camera functionality.
2Length of moving object
If the camera phone is made thinner for portability, then ease of carrying is improved, but protection against external impact deteriorates
Solution Approach 1:
The patent employs flexible protective films and thin protective shells that can be applied to the camera phone surface. These thin protective layers provide impact protection while maintaining the device's thin profile and portability, preventing the need to increase thickness for protection.
3Measurement precision
If glass materials are used for display device and lens, then optical performance is improved, but susceptibility to external impact deteriorates
Solution Approach 1:
The patent uses composite material structures where glass display devices and lenses are combined with protective coating layers or protective frames made of more impact-resistant materials. This composite approach maintains the optical performance of glass while adding protection against external impacts.
4Object-affected harmful factors
If adequate protection structures are added to protect display and lens, then protection against external impact is improved, but device complexity deteriorates
Solution Approach 1:
The patent designs protective structures that serve multiple functions simultaneously. For example, the protective frame not only protects against impact but also provides structural support, while protective coatings simultaneously protect against scratches and impacts. This multi-functionality reduces the need for separate protective components, simplifying the overall structure.
