Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access door and switch actuator designs often require multiple components and materials, increasing complexity and component count, whereas integrating these functions into a single composite component can simplify device design and reduce material usage.
Innovation Solution
A single composite component with a switch actuator in a fixed position and a hinged door that provides access to an internal area, utilizing a living hinge and locking mechanism to allow the door to pivot while maintaining the actuator in a fixed position, made from durable materials like plastic or rubber, and attached using methods such as heat staking, adhesives, or mechanical fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple separate components are used for access door and switch actuator, then each component can be optimized independently, but the overall device complexity and component count increases
Solution Approach 1:
The patent combines the access door and switch actuator into a single integrated component. The actuator is formed as an integral part of the door assembly, eliminating the need for separate components. This merging reduces component count and simplifies the overall device structure while maintaining the ability to independently optimize the combined function.
Solution Approach 2:
The integrated component serves multiple functions: it provides access to the SIM card tray when opened and simultaneously acts as a switch actuator when pressed. This multi-functionality eliminates the need for separate access door and switch components, reducing overall device complexity while maintaining independent optimization capabilities.
2Device complexity
If a single composite component is used for access door and switch actuator, then component count and material usage are reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The access door and switch actuator are merged into a single molded component, reducing component count and material usage. The integration is achieved through co-molding or overmolding processes that are well-established in plastic manufacturing, thereby managing precision requirements through proven manufacturing techniques rather than introducing entirely new processes.
Solution Approach 2:
The patent uses composite material construction with a rigid base material for structural integrity and a softer overmolded material for the actuator surface. This composite approach allows each material to be optimized for its specific function while being manufactured as an integrated piece, balancing manufacturing precision requirements with material properties.
3Ease of operation
If the door is made hinged and movable, then access to internal areas is enabled, but the switch actuator position stability may be compromised
Solution Approach 1:
The integrated component is segmented into functional zones: a hinged door portion for access and a fixed actuator portion for switching. The hinge mechanism is designed to allow door movement while the actuator remains in a fixed, stable position. This segmentation enables independent optimization of movement and stability within the same integrated component.
Solution Approach 2:
Different regions of the integrated component have different properties: the door region is designed for movement with appropriate hinge attachment, while the actuator region is designed for fixed positioning with increased rigidity. This local differentiation of properties allows the door to be movable for access while maintaining actuator position stability.

Function Achieved in This Case
This integrated design reduces the number of components and materials needed, simplifies installation, and provides a flexible, durable solution for accessing internal device areas while maintaining functionality, such as resetting a mobile device, by allowing the door to swing open without disturbing the fixed actuator position.
Implementation Method 1
The living hinge is made of the same material as the first material. The living hinge bends causing the second material to move in an angular direction along the second edge.
Implementation Method 2
attached using methods such as heat staking, adhesives, or mechanical fasteners
