Connector With Displaceable Holding Unit for Window Film
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector terminal structures are limited to resin-made window plates and cannot be applied to window frames made of other materials, as they require integration with the resin-made window plate for electrical connection.
Innovation Solution
A connector design featuring a housing with a holding unit that can displace between temporal and non-temporal locking positions, allowing for flexible attachment to various base materials using adhesives or screws, and an elastically deformable terminal that contacts the conductive film only in the non-temporal locking position for secure electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the connector terminal is inserted into the terminal holder integrally formed with the resin-made window plate, then electrical connection is achieved, but the connector cannot be applied to window frames made of other materials
Solution Approach 1:
The connector is divided into separate components: a housing that can be fixed to different base materials (glass, resin, metal) and a terminal holder assembly that can be independently attached. This segmentation allows the same connector design to be adapted to various window frame materials without requiring integral formation with the base material.
Solution Approach 2:
The housing is designed with universal fixing capabilities that can accommodate multiple base materials (glass, resin, metal) through different fixing methods (adhesive, screw, clamp). This universal design enables the same connector structure to serve multiple applications across different vehicle window types.
2Reliability
If the terminal contacts the conductive film during fixation, then electrical connection is established, but stress acts on the connector when fixed with adhesive or screw
Solution Approach 1:
The housing is fixed to the base material first in a temporal locking position where the terminal does not contact the conductive film. This preliminary fixation establishes a stable mechanical foundation before electrical connection is made, preventing stress on the connector during the fixation process.
Solution Approach 2:
The terminal holder assembly is designed to be movable relative to the housing, transitioning from a temporal locking position (during fixation) to a non-temporal locking position (during operation). This dynamic positioning allows the terminal to contact the conductive film only after the housing is securely fixed, eliminating stress during fixation while ensuring reliable electrical connection during use.
3Reliability
If the terminal is elastically deformed to contact the conductive film, then electrical connection is achieved, but the terminal may contact exterior members causing contamination
Solution Approach 1:
The terminal holder assembly is nested within or integrated with the housing structure, which provides a protective enclosure. The terminal can elastically deform to contact the conductive film while remaining contained within the housing, preventing contact with exterior members and contamination from dust.

AI summary
A male connector includes a housing fixed to a base, a holding unit supported in such a manner as to enable displacement with respect to the housing; and an elastically deformable male terminal held by the holding unit. The housing is able to maintain the holding unit in a stationary state with the terminal undeformed and apart from the conductive film, while the holding unit is in the temporal locking position with the housing fixed to the base. The housing is able to maintain the holding unit in a stationary state with the terminal elastically deformed and contacting the conductive film, while the holding unit is in the non-temporal locking position with the housing fixed to the base.
