Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional halogen lamps used for semiconductor wafer heating require significant force for replacement, leading to potential breakage, uneven heating due to unstable terminal connections, and difficulty in ensuring complete insertion, causing variations in heat generation among lamps.
Innovation Solution
A power supply socket design featuring a first holder part, a second holder part, and a spring member with a third hole that allows the terminal to pass through, enabling easy attachment and removal by rotating the halogen lamp, providing a secure and stable contact through a biasing force, reducing the risk of breakage and ensuring uniform heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal is inserted straight into the power supply socket to ensure stable contact, then electrical connection stability is improved, but the force required for attachment and removal increases significantly
Solution Approach 1:
The patent changes the insertion direction from linear (straight in) to rotational (turning motion). The terminal is inserted through holes extending in a direction different from the insertion direction, and then rotated 90 degrees to engage with the external electrode terminals. This dimensional change from linear to rotational motion reduces the attachment force while maintaining connection stability.
Solution Approach 2:
The patent introduces a spring member that provides elastic force to maintain contact between the terminal and external electrode terminals. The spring member allows for dynamic adjustment and compensation, ensuring stable electrical connection while reducing the force needed for initial attachment and removal.
2Reliability
If the terminal is inserted deeply into the socket to ensure complete contact, then electrical connection reliability is improved, but the risk of breakage or crack increases due to excessive force
Solution Approach 1:
The rotational insertion mechanism allows the terminal to engage with the external electrode terminals through a turning motion rather than forcing it straight in. This reduces the risk of breakage or cracking while ensuring complete contact and reliable electrical connection.
Solution Approach 2:
The spring member provides elastic cushioning that prevents excessive force from being applied to the terminal during attachment. The spring absorbs and distributes the force, protecting the terminal from breakage or cracking while ensuring proper engagement.
3Volume of moving object
If the socket hole is made narrow to maintain compact structure, then device compactness is improved, but visual confirmation of terminal insertion becomes difficult
Solution Approach 1:
The patent utilizes the change in orientation of the terminal during rotation to provide visual feedback. As the terminal rotates 90 degrees during insertion, its position and orientation change become visible, allowing operators to confirm proper insertion without needing to see deep into the narrow socket hole.
4Ease of operation
If the terminal insertion depth varies among lamps to facilitate easy replacement, then ease of operation is improved, but uniformity of heat generation deteriorates
Solution Approach 1:
The rotational insertion mechanism ensures that all terminals are inserted to the same depth and orientation through a standardized 90-degree rotation motion. This eliminates variations in insertion depth that would occur with manual linear insertion, ensuring uniform electrical contact area and consistent heat generation across all lamps.
Solution Approach 2:
The spring member provides consistent elastic force that ensures uniform contact pressure and electrical connection for all terminals, regardless of minor variations in insertion timing or operator force. This maintains uniform heat generation while allowing easy lamp replacement.

AI summary
To provide a socket for a halogen lamp, which allows easy attachment and removal operations, as well as enables stable contact between a lamp terminal and an external electrode terminal when the lamp is attached. The socket includes a first holder part having a first hole, a second holder part having a second hole, and a spring member accommodated at a position between the first hole and the second hole and having a third hole. The first hole, second hole, and third hole have a shape extending in a direction that is different from a direction in which the terminal is passed through. The terminal is turned after being passed through the holes, whereby the terminal moves inside the first hole, second hole, and third hole, and is fixed when the terminal reaches an outer edge portion of the third hole of the spring member.
