Blinker Device Mounting Base With Integrated Wiring And Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blinker devices with elastic mounting bases face issues of exposed screw heads and increased size due to the need for additional holes for wiring and fastening, affecting appearance and aerodynamics.
Innovation Solution
The design incorporates a fixing member with a halved cylindrical portion and tubular collar to guide wiring and fastening, using a cut-away wiring hole and side-by-side placement of fastening and wiring holes to minimize size and prevent exposure, along with a cylindrical boss for secure mounting and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the screw that fixes the retainer and the elastic member is screwed from the outer side in the radial direction of the elastic member, then the fixing is reliable, but the screw head and the boss portion are exposed to the outside and influence the appearance of the blinker device
Solution Approach 1:
The patent inverts the screwing direction from the conventional outer side to the inner side by making the retainer insertion direction and the screw insertion direction coincide. The fixing screw is inserted from the inner side of the exterior component through the retainer, so the screw head is not exposed outward, solving the appearance problem while maintaining fixing reliability through the integrated retainer-screw structure
2Shape
If the screw that fixes the retainer and the elastic member is oriented in the retainer insertion direction and screwed from the inside of the exterior component, then the appearance is improved, but an insertion hole for the fixing screw needs to be provided in addition to an insertion hole for wiring, and the mounting base portion tends to increase in size
Solution Approach 1:
The patent merges the retainer insertion function and the screw insertion function into a single integrated structure. The retainer itself forms the screw insertion hole, eliminating the need for a separate fixing screw hole. This allows both wiring and fastening to share the same insertion path, preventing an increase in mounting base portion size while maintaining improved appearance
3Ease of manufacture
If multiple insertion holes are provided for wiring and fastening, then the wiring and fastening can be performed separately, but the mounting base portion increases in size and affects aerodynamics
Solution Approach 1:
The retainer structure is designed to serve multiple functions: it acts as both the insertion guide for wiring and the fastening mechanism for the blinker device. The single insertion hole accommodates both the wiring passage and the fastening screw, making the mounting base portion multi-functional and preventing size increase while maintaining ease of assembly
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for a compact, aesthetically pleasing, and aerodynamically improved blinker device by reducing the vertical dimension of the mounting base and preventing erroneous fitting, while ensuring reliable fastening and wiring guidance.
Implementation Method 1
the elastic member (60) is configured to be capable of being fitted to and removed from the fixing portion (24a) by elastically deforming a part of the elastic member (60)
Data Source
AI summary
The elastic member (60) is enabled, by temporarily elastically deforming a part thereof, to be fitted with and removed from the fixing portion (24a), and is provided with a tabular fixing member (80) that prevents elastic deformation of the elastic member (60) by being fixed to the elastic member (60), and a fastening member (90) that integrally fixes the blinker housing (51), the elastic member (60), and the fixing member (80). In the fixing member (80), a fastening hole portion (86) through which the fastening member (90) is inserted and a wiring hole portion (83) through which a wiring (92) that supplies electricity to the light source (54) is inserted are disposed side by side to each other, and in the wiring hole (83), a cut-away (83a) to open a part of the wiring hole (83) is provided.
