Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face challenges in protecting internal components from moisture and dust due to multiple openings required for key devices, which compromise water resistance and design flexibility.
Innovation Solution
A mobile terminal design featuring a lid unit with integrated key devices that controls functions, reducing the number of openings and utilizing sealing means to enhance water protection, allowing access to internal components while minimizing moisture ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple separate openings are provided for key devices and component access, then functional accessibility is improved, but water protection and design flexibility deteriorate
Solution Approach 1:
The patent combines the key device opening and component access opening into a single integrated opening in the housing. This allows both the key device and internal components (such as battery, SIM card, or memory card) to be accessed through the same opening, thereby reducing the total number of openings and improving water protection while maintaining full functional accessibility.
Solution Approach 2:
The single opening serves multiple functions: it provides access for the key device to control terminal functions, allows replacement of internal components, and maintains a sealed structure for water protection. This multi-functional design eliminates the need for separate dedicated openings for each function.
2Adaptability or versatility
If multiple separate openings are provided for key devices, then functional control is improved, but design flexibility and sealing complexity increase
Solution Approach 1:
The patent merges multiple openings into one unified opening structure, which significantly simplifies the sealing design. Instead of requiring multiple separate seals for different openings, a single seal structure can be used, reducing sealing complexity and improving design flexibility.
Solution Approach 2:
The unified opening design allows the same structural opening to serve multiple purposes (key device access, component replacement), providing design flexibility without requiring additional separate openings or complex sealing arrangements for each function.
3Ease of operation
If multiple openings are provided in the housing, then access to components is improved, but housing strength and water resistance decrease
Solution Approach 1:
The patent combines multiple access openings into a single opening, which maintains housing strength by minimizing the number of openings in the housing structure. The single opening is strategically positioned and sized to provide adequate access for both key device operation and component replacement while preserving overall structural integrity.
Solution Approach 2:
The single multi-functional opening provides component accessibility and key device control without requiring multiple separate openings, thereby maintaining housing strength and water resistance while still allowing easy access to internal components when needed.
