Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If additional battery packs are coupled to protective devices to increase operating times, then the operating time between charges is extended, but the device becomes bulky and cumbersome
Solution Approach 1:
The patent combines the protective case and charging device into a single integrated unit. The housing that protects the mobile input device also contains the energy storage device, eliminating the need for separate battery packs while providing both protection and extended operating time.
Solution Approach 2:
The housing serves multiple functions simultaneously: it protects the mobile input device from damage, houses the energy storage device for charging, and provides a slot for securing the device. This multi-functionality reduces the need for additional separate components.
2Stability of the object's composition
If a slot is designed to secure mobile input devices in upright configuration, then the device stability is improved, but the slot design complexity increases
Solution Approach 1:
The slot includes curved inner walls that conform to the shape of the mobile input device. This curvature allows the device to be secured in an upright position while distributing contact forces evenly, achieving stability without complex mechanical structures.
Solution Approach 2:
The inner walls of the slot have localized friction-enhancing features at specific contact points. This provides the necessary grip for stability only where needed, rather than requiring the entire slot structure to be complex.
3Stability of the object's composition
If the slot is over-molded with rubber or PU coating to increase friction, then the device stability is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The slot is manufactured using over-molding to create a composite structure where a rubber or polyurethane layer is bonded to the housing material. This provides high-friction contact surfaces for device stability while using a established manufacturing process that is relatively simple to implement.
4Adaptability or versatility
If the slot extends along the long edge of the housing, then the device can be secured in multiple orientations, but the housing space for energy storage is reduced
Solution Approach 1:
The slot is designed as a narrow, elongated structure that extends along the long edge of the housing, occupying minimal cross-sectional area. This segmentation allows the housing space to be divided efficiently, with the slot providing multi-orientation support while leaving the bulk of the housing volume available for energy storage.

AI summary
Embodiments of the invention relate to an apparatus comprising a housing having a substantially rectangular shape and including a top side, a bottom side, and a slot that passes from the top side to the bottom side of the housing to secure a mobile input device in an upright configuration. The apparatus further includes an energy storage device disposed within the housing to charge the mobile input device. The energy storage device may charge the mobile input device by inductive charging or hardwire (e.g., via a retractable cable). The slot can include a coating or covering to increase a coefficient between the slot and the mobile input device. The slot can be disposed in the long end of the housing and can support the mobile input device in either a portrait or landscape upright configuration, from either the top end or the bottom end.
