Shielding Member for Sliding Handheld Device Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld electronic devices with sliding-type designs face limitations in available space and structural design due to the need to protect flexible printed circuits, which restricts the spreading area and exposes the circuits, affecting reliability and exterior aesthetics.
Innovation Solution
A handheld electronic device design featuring a shielding member that covers the opening when the device is spread, using driving members and a sliding module to protect the flexible electrical connecting member, allowing for a larger spreading area and improved reliability while maintaining an artistic exterior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the spreading area of the two bodies is increased, then the available space and design flexibility are improved, but the opening is enlarged causing the flexible printed circuit to be exposed and reliability to decrease
Solution Approach 1:
A shielding member is introduced as an intermediary component between the flexible printed circuit and the external environment. This shielding member selectively covers the opening to protect the flexible printed circuit from exposure while allowing the two bodies to maintain a larger spreading area, thus resolving the contradiction between increased spreading area and maintained reliability
Solution Approach 2:
The opening is segmented into a covered portion and an exposed portion through the shielding member. This segmentation allows different functional zones: the covered portion protects the flexible printed circuit for reliability, while the exposed portion maintains aesthetic appearance and allows the overall spreading area to be enlarged
2Adaptability or versatility
If the spreading area of the two bodies is increased, then the design flexibility is improved, but the exterior design is affected due to the exposed flexible printed circuit
Solution Approach 1:
The shielding member serves as a mediating element that separates the functional requirement (protecting the flexible printed circuit) from the aesthetic requirement (maintaining exterior design). It allows the opening to be selectively covered, preserving the exterior appearance while enabling larger spreading area for design flexibility
Solution Approach 2:
The shielding member applies local quality by selectively covering only the necessary portion of the opening where the flexible printed circuit is located, while leaving other portions exposed. This localized approach maintains the overall exterior design aesthetic while providing targeted protection, enabling design flexibility without compromising appearance
3Reliability
If the two bodies maintain stacked position to protect the flexible printed circuit, then the reliability is improved, but the available space is limited
Solution Approach 1:
The shielding member is configured to dynamically change its position between covering and non-covering states based on the relative position of the two bodies. When the bodies are stacked, the shielding member covers the opening to protect the flexible printed circuit. When the bodies are spread, the shielding member can be repositioned to allow the opening to be exposed, thus enabling the system to adapt to different states and resolve the contradiction between reliability and available space

AI summary
A handheld electronic device including a first body, a second body, a sliding module, and a shielding member is provided. The sliding module drives the first body and the second body transforming between a retracting state and a spreading state. The sliding module includes a sliding member, a fixing member and a driving member. The sliding member has an opening and when the first body and the second body configure in the spreading state, a part of the opening is exposed. The shielding member is coupled to the driving member. When the first body and the second body are transformed from the retracting state to the spreading state, the driving member drives the shielding member sliding with respect to the sliding member to shield the part of the opening.
