Server Casing Bracket Neutralizes Weight Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rack server housings deform under the weight of internal members, preventing maintenance and repair due to limited space and weight distribution, which interferes with the ability to open lower housings when upper housings are deformed.
Innovation Solution
A casing structure with a bracket system that provides positive deformation to counteract the negative deformation caused by the weight of members on the circuit board and housing, maintaining them on a horizontal plane and allowing smooth movement in and out of the rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If members are arranged in each housing to increase space utilization and server efficacy, then the weight of members brings great load to the mother board and housing, but the housing deforms along the gravity direction and prevents maintenance
Solution Approach 1:
The patent applies the anti-weight principle by introducing a bracket structure that provides upward support force to counteract the downward gravitational force of the members. The bracket is connected to the housing and the mother board, creating a counterbalancing mechanism that offsets the weight-induced deformation, thereby maintaining housing structural integrity and accessibility for maintenance while supporting heavy members.
Solution Approach 2:
The bracket serves as an intermediary structure between the housing and the mother board. Instead of allowing the members' weight to directly deform the housing and circuit board, the bracket mediates this interaction by providing structural support and distributing the load, thus preventing deformation while enabling maintenance access.
2Ease of manufacture
If the cabinet is made of light weight to reduce manufacturing cost, then the housing has less structural strength, but it cannot bear the load of multiple members without deformation
Solution Approach 1:
The patent merges the housing, bracket, and mother board into an integrated load-bearing system. The bracket connects the housing to the mother board, creating a combined structure that distributes the weight of members across multiple components. This allows the housing to remain lightweight for cost-effectiveness while the integrated structure provides the necessary strength to bear heavy members without deformation.
Solution Approach 2:
The bracket is pre-assembled between the circuit board and the cover before the members are installed. This preliminary action prepares the structure to bear the upcoming load, ensuring that when heavy members are added, the deformation is already counteracted by the pre-positioned bracket, maintaining housing integrity without requiring heavier materials.
3Productivity
If not much space is reserved between adjacent server units to maximize space utilization, then the housing deforms under member weight, but this deformation prevents lower housing from being opened for maintenance
Solution Approach 1:
The bracket provides counterbalancing support force to offset the gravitational deformation caused by members. This prevents the housing from tilting or deforming downward, ensuring that the housing remains properly aligned and accessible for maintenance operations even when server units are tightly packed with maximum space utilization.
Solution Approach 2:
The bracket acts as an intermediary support structure that decouples the relationship between member weight and housing deformation. By introducing this intermediate element, the housing can maintain its operational accessibility while supporting heavy members in a compact arrangement, enabling maintenance access without requiring additional spacing between units.

AI summary
A server including a housing, a circuit board, a bracket, and multiple members is provided. The housing has a bottom case and a cover assembled to the bottom case in an open or a closed manner. The circuit board is disposed on the bottom case. The bracket is assembled between the bottom case and the cover. The cover and the bracket deform the bottom case in a positive way. The members are disposed on the circuit board. The members deform the circuit board and the bottom case in a negative way with the weight thereof. The positive deformation and the negative deformation of the bottom case are neutralized, such that the bottom case and the circuit board are maintained on a horizontal plane.
