Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strip light switches face issues with permanent deformation or breakage of contact legs during assembly, leading to contact failures and increased repair costs, as well as burr and fouling from insert molding, which complicates maintenance and reduces product yield.
Innovation Solution
The strip light switch design features detachable mating connection terminals in positioning grooves within an insulative housing, eliminating the need for bending contact legs and avoiding the use of running sliders, allowing for easy replacement of damaged terminals and preventing deformation, while ensuring stable electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If contact legs are bent to mount conducting plates in the press device, then the press device can be installed in the accommodation chamber, but the contact legs may be permanently deformed or broken leading to contact failure
Solution Approach 1:
The invention divides the conducting plate into two separate parts: the main body mounted in the press device and the contact legs that extend outward. This segmentation allows the contact legs to be independently positioned and connected to the terminal set without requiring excessive bending, thereby reducing the risk of permanent deformation or breakage while enabling proper installation of the press device in the accommodation chamber.
2Strength
If insert molding technology is used to mount the terminal set, then the terminals can be securely fixed in the accommodation chamber, but burr and fouling are produced between the accommodation chamber and mating connection members
Solution Approach 1:
The invention extracts the harmful byproducts (burr and fouling) from the assembly process by eliminating the insert molding technology. Instead, the terminal set and mating connection members are designed with precise fitting structures that achieve secure fixation without requiring high-force insertion processes that generate burr and fouling, thereby maintaining fixing strength while removing harmful factors.
3Ease of operation
If the press device is frequently pressed or pressed with large force, then the light-emitting component can be activated, but the contact legs of the conducting plates are squeezed to deform leading to contact failure
Solution Approach 1:
The invention performs preliminary action by pre-positioning the contact legs in optimal locations and pre-configuring their geometry before the pressing operation. The contact legs are designed with appropriate length, angle, and positioning features that enable them to maintain stable electrical contact with the terminal set even when the press device is frequently pressed or pressed with large force, preventing deformation and contact failure during operation.
4Ease of manufacture
If running sliders are used in insert molding, then the terminal set can be mounted in the accommodation chamber, but burr and fouling are produced increasing product defect rate
Solution Approach 1:
The invention extracts and eliminates the running sliders from the manufacturing process. The terminal set is designed with alternative mounting structures that achieve secure fixation in the accommodation chamber without requiring running sliders, thereby preventing the generation of burr and fouling that would otherwise increase product defect rates and reduce yield.
