Split Cue Rear Section for Lower-Cost Rod Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing billiard cues with integrated rod bodies require complete replacement when damaged, leading to high maintenance costs.
Innovation Solution
A split-type assembled billiard cue design comprising a cue rear section with a first and second rod body, a connecting pin, and a counterweight placement cavity, allowing separate replacement of the first rod body and simplified assembly/disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an integrated rod body structure is used in the cue rear section, then the structural strength and simplicity are improved, but the maintenance cost increases when damage occurs
Solution Approach 1:
The rod body is divided into multiple sections: a first rod body section containing the placement cavity and counterweight, and a second rod body section. This segmentation allows the first rod body to be replaced independently when damaged, reducing maintenance costs while maintaining overall structural integrity through the connection between sections.
2Ease of repair
If a split-type assembled structure is used with separate rod body sections, then the ease of repair and replacement is improved, but the device complexity increases
Solution Approach 1:
The cue rear section is segmented into a first rod body and a second rod body that can be assembled and disassembled separately. The first rod body contains a placement cavity for the counterweight, allowing independent replacement of damaged components without replacing the entire rod body, thus improving ease of repair while maintaining reasonable structural complexity.
3Ease of operation
If the placement cavity extends to the end face of the tail end, then the ease of assembly and disassembly is improved, but the structural stability may be affected
Solution Approach 1:
The placement cavity extends to the end face of the tail end of the first rod body, allowing the counterweight to be easily inserted and removed. The cavity is bounded by a bottom wall and side walls that provide structural support, maintaining stability while enabling easy assembly and disassembly operations.

AI summary
A split-type assembled billiard cue including a cue rear section. The cue rear section includes a first rod body, a second rod body, a connecting pin for fixation with a cue front section, and a counterweight. In this solution, the first rod body and the second rod body, in combination with the connecting pin, form the cue rear section. The counterweight is placed in a placement cavity of the first rod body. The first rod body or the first rod body, when damaged, can be replaced separately, thereby reducing the subsequent maintenance cost.
