Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing force boosting mechanisms for inserting and extracting controllers in electronic computers are complex, costly, and lack flexibility in component arrangement, making it difficult to achieve the desired action length and force in limited spaces.
Innovation Solution
A booster lever unit with a simple structure, featuring a first lever, a second lever, and a linkage member, where the levers are pivotably supported by a predetermined object via pivotal shafts, and the linkage member links the levers to each other, allowing for a high degree of freedom in component arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a force boosting mechanism combining leverage mechanism and toggle mechanism is employed, then the desired action force can be achieved, but the structure becomes complicated and component arrangement flexibility is reduced
Solution Approach 1:
The force boosting mechanism is divided into two independent lever mechanisms (first lever mechanism and second lever mechanism) that operate separately but coordinate through a common linkage member. This segmentation allows each lever to be optimized independently while maintaining overall simplicity and flexibility in component arrangement.
2Force
If a complex force boosting mechanism is used, then sufficient action force is provided, but the cost increases
Solution Approach 1:
Two lever mechanisms are merged into a single integrated system sharing a common linkage member and pivot support structure. This merging reduces the total number of components compared to using a complex toggle mechanism, lowering manufacturing costs while maintaining the required force boosting capability.
3Reliability
If a standardized force boosting mechanism is employed, then reliable force boosting is achieved, but flexibility in component arrangement in limited space is reduced
Solution Approach 1:
The lever mechanisms are designed with pivotable connections and a linkage member that allows dynamic adjustment of component positions and orientations. This dynamic design enables the mechanism to adapt to different spatial configurations within the server rack while maintaining reliable force boosting functionality.

AI summary
A booster lever unit includes a first lever pivotably supported by an object via a first pivotal shaft, a second lever pivotably supported by the object via a second pivotal shaft, and a linkage member that links the first lever to the second lever. The pivotal plane of the first lever is parallel to the pivotal plane of the second lever. The first lever has one end provided with an operation section, and another end provided with the first pivotal shaft, and the first lever further includes a first linker, the first linker being provided between the operation section and the first pivotal shaft and linked to the linkage member. The second lever has one end provided with an action section, and another end provided with a second linker linked to the linkage member, and the second pivotal shaft is provided between the action section and the second linker.
