Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a mobile station stores a large amount of information including MBMS service information and system information for each cell, then the mobile station can quickly access required information without frequent requests to the base station, but the information storage capacity and memory requirements of the mobile station increase
Solution Approach 1:
The information storage is segmented into two parts: frequently accessed information (MBMS service information) is stored in the mobile station's buffer, while less frequently accessed information (system information) is stored in the base station. This segmentation allows the mobile station to reduce its storage requirements while maintaining fast access to critical information.
Solution Approach 2:
The patent introduces a new dimension of information delivery by implementing a multicast delivery mechanism for system information. Instead of unicast delivery for each mobile station, system information is transmitted through a multicast channel, allowing multiple stations to access the same information efficiently without increasing individual mobile station storage requirements.
2Reliability
If the network transmits system information to each mobile station individually through unicast, then each mobile station receives accurate and dedicated information, but the network bandwidth consumption and transmission resources increase significantly
Solution Approach 1:
The patent implements a universal information delivery mechanism where a single multicast transmission of system information serves multiple mobile stations simultaneously. This multi-functional approach allows the same information channel to serve different users with similar information needs, reducing overall network bandwidth consumption while maintaining information delivery accuracy through standardized multicast protocols.
3Measurement precision
If the mobile station frequently requests and updates information from the base station, then the information remains current and accurate, but the signaling overhead and network traffic increase
Solution Approach 1:
The base station performs preliminary actions by pre-configuring and broadcasting system information through multicast channels before mobile stations need to access it. This advance preparation allows mobile stations to receive updated information passively without needing to initiate frequent active requests, thereby maintaining information accuracy while reducing signaling overhead.
Solution Approach 2:
The patent implements a feedback mechanism where mobile stations can indicate their information needs and reception status to the base station. This feedback allows the base station to optimize its multicast transmissions, sending information only when necessary and only to stations that need it, thereby maintaining information accuracy while minimizing unnecessary signaling overhead.

AI summary
The present invention provides an access station (7) for a storage system, the access station comprises at least one container holder (8a,8b) arranged to rotate about an axis of rotation (C), wherein the axis of rotation (C) is inclined at a first angle (X) relative to a vertical (V); and the container holder (8a,8b) is arranged to accommodate a storage container (106) and is configured such that a centreline (D) of the storage container (106) when supported by the container holder is inclined at a second angle (Y) relative to the axis of rotation (C), wherein the container holder (8a,8b) may rotate between a first position (P1), where the centreline (D) of an accommodated storage container (106) is vertical, and a second position (P2) being opposite the first position relative to the axis of rotation (C), where the centreline (D) of an accommodated storage container (106) is inclined at a third angle (XY) relative to the vertical (V), the third angle being equal to the sum of the first angle and the second angle.
