Tuner Frame With Through-Hole And Stopper For Connection Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the production of circuit apparatuses like tuners, inadequate temporary fixing of connection bases to frames during the soldering process leads to movement issues, causing inefficiencies in mounting circuit boards and potentially resulting in unsuccessful assembly.
Innovation Solution
A tuner design featuring a frame with a through-hole and a flange portion that can be rotated to pass through or not pass through the hole, along with a pressurization portion that secures the flange in place, ensuring stable fixation without compromising workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connection base is temporarily fixed to the frame by simple insertion, then the ease of operation is improved, but the reliability of fixation deteriorates causing movement during soldering
Solution Approach 1:
The connection base incorporates a rotatable flange portion that transitions from a loose state during insertion to a locked state during soldering. The flange rotates from an initial position where it passes through the through-hole freely to a final position where it abuts against a stopper portion, dynamically changing its fixation state based on operational stage.
Solution Approach 2:
The stopper portion is pre-positioned on the frame to prepare for the flange's rotation. Before soldering begins, the flange is rotated to engage with the pre-positioned stopper, establishing preliminary fixation that prevents movement during the subsequent soldering process.
2Reliability
If the connection base is firmly fixed before soldering, then the reliability of fixation is improved, but the ease of operation deteriorates due to complex fixing procedures
Solution Approach 1:
The connection base performs its own fixation operation by rotating the flange portion. The operator simply inserts the connection base and rotates the flange, which automatically engages with the stopper portion to achieve firm fixation without requiring additional fixing components or complex procedures.
Solution Approach 2:
The fixation function is extracted from the through-hole structure and embodied in the rotatable flange portion. The flange serves as a dedicated fixation mechanism that separates the insertion function (through-hole) from the fixation function (flange rotation), simplifying both structures while improving reliability.
3Reliability
If the connection base moves during soldering, then the reliability of assembly deteriorates, but adding complex fixation mechanisms increases device complexity
Solution Approach 1:
The flange portion serves multiple functions: it provides the mounting interface for the connection base, acts as a rotation mechanism for fixation, and functions as a positioning element that abuts against the stopper. This multi-functionality achieves reliable assembly fixation without adding separate dedicated components.
Solution Approach 2:
The fixation mechanism is merged with the connection base structure itself through the integrated flange portion. Rather than adding a separate fixation device, the flange is combined with the connection base body, achieving reliable fixation while minimizing device complexity.

AI summary
A tuner comprises a frame that is provided with a through-hole and a connection portion to which a connector is connected. The connection portion includes a flange portion that is able to select to pass through the through-hole or not to pass through the through-hole by the connection portion being rotated, and the frame includes a pressurization portion that pressurizes the flange portion which passes through the through-hole.
