Removable Endpiece Case for Screen-Safe Docking Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cases for portable electronic devices often require insertion through the device's screen area, which can lead to damage and are not designed for secure retention without obstructing the screen, and lack efficient integration with external docking systems.
Innovation Solution
A case design featuring a side opening for device insertion, a removable endpiece with a male plug and contacts for electrical coupling, and a tab/receptacle mechanism for secure retention, allowing full or partial endpiece insertion within the case, and integration with docking systems through asymmetric connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the case requires insertion through the device's screen area, then the device can be protected, but the screen may be damaged and insertion is difficult
Solution Approach 1:
The case is divided into a main body portion and a separate endpiece that can be inserted independently through the side opening. This segmentation allows the case to be assembled without forcing components through the screen area, eliminating screen damage risk while maintaining protective function.
Solution Approach 2:
Instead of inserting the case from the front (screen side) as in conventional designs, this invention inserts the endpiece from the side opening and engages it with the device's port. This inverted insertion approach completely avoids contact with the screen area, resolving the contradiction between protection and screen safety.
2Ease of operation
If the case uses a side opening for insertion, then screen obstruction is avoided, but secure retention of the device may be compromised
Solution Approach 1:
The endpiece serves as an intermediary component that bridges the side opening insertion method with secure device retention. It engages with the device's port and internal structures to provide anchoring, while the main case body provides external protection, together achieving both screen accessibility and reliable retention.
Solution Approach 2:
The endpiece nests within the case body and engages with the device's internal port structure, creating a nested assembly that secures the device. This nested configuration allows the case to retain the device securely while maintaining side opening insertion that does not obstruct the screen.
3Adaptability or versatility
If the case integrates docking functionality, then external system integration is enabled, but device complexity increases
Solution Approach 1:
The endpiece is designed with multi-functionality, serving both as a structural component for secure retention and as a docking interface for external systems. By integrating the male plug and contacts into the endpiece, the case achieves universal compatibility with docking stations without requiring separate components, thereby managing complexity while enhancing adaptability.

AI summary
A case includes a shell having a back panel, a front panel, and at least one side wall that define a cavity for receiving the portable electronic device and a side opening between the back panel and the front panel for insertion of a portable electronic device. The case further includes a removable endpiece having a base and, optionally, an adapter, which includes a male plug for insertion into a female port of the portable electronic device, a contactor opposite the male plug, first contacts disposed on the male plug, and second contacts disposed on the contactor. The removable endpiece is configured for insertion through the side opening into the cavity. The removable endpiece includes at least one tab and the shell defines at least one tab receptacle along the side opening to receive the at least one tab of the removable endpiece.
