Vehicle Block Elastic Support Bars Temporary Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of vehicle blocks with multiple electric/electronic parts is challenging due to the risk of damage from housing parts interference, and existing methods face difficulties in maintaining a secure temporarily assembled state and efficiently inserting small-sized parts without causing them to move within narrow mounting spaces.
Innovation Solution
A vehicle block design featuring a main housing with elastically deformable support bars and temporary fastening portions, along with secondary fastening tabs, allows for secure temporary assembly and easy insertion of parts, preventing damage and movement during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If housing parts are temporarily assembled before inserting small-sized electric/electronic parts, then the parts can be naturally and completely assembled, but it is difficult to temporarily assemble the housing parts or complete assembly is undesirably performed by external force
Solution Approach 1:
The support bars are designed to be elastically deformable, allowing the temporary fastening portions to be inserted and held in a temporarily assembled state. The elastic deformation enables the support bars to flex during assembly and then maintain the temporary state without complete assembly, resolving the contradiction between ease of insertion and stability of temporary assembly.
2Productivity
If mounting spaces are increased to enable easy insertion of small-sized parts, then assembly efficiency improves, but the electric/electronic parts move within the mounting spaces
Solution Approach 1:
The housing is divided into upper and lower cases with distinct functions. The upper case contains mounting spaces for electric/electronic parts, while the lower case provides structural support and contains the support bars. This segmentation allows the mounting spaces to be sufficiently large for easy insertion while the lower case with support bars prevents part movement, resolving the contradiction between assembly efficiency and position stability.
3Shape
If small-sized parts are inserted through narrow mounting spaces, then the block structure is maintained, but the efficiency of assembly is degraded
Solution Approach 1:
The temporary fastening portions are nested within the mounting spaces during assembly. The temporary fastening portions protrude from the upper case and engage with the support bars in the lower case, allowing parts to be inserted through adequately sized spaces while maintaining the compact block structure. The nested arrangement resolves the contradiction between compact structure and assembly efficiency.
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
The design enhances assembly efficiency by securely maintaining the temporarily assembled state, reducing part damage, and allowing for easy insertion and complete mounting of electric/electronic components without manual force, thereby improving overall assembly efficiency and stability.
Implementation Method 1
support bars configured to protrude upward from edges of the main housing surrounding the upper housing, and to be elastically deformable in a direction away from the main housing

AI summary
Provided is a block for a vehicle. The block for a vehicle includes a main housing, an upper housing, support bars, and temporary fastening portions. The main housing has a first containing space. The upper housing has a second containing space. At least part of the upper housing is inserted into the main housing. The support bars protrude upward from edges of the main housing, and are elastically deformable in a direction away from the main housing. The temporary fastening portions protrude downward from edges of the upper housing. When the temporary fastening portions are seated on the upper portions of the support bars, the upper housing is temporarily fastened to the main housing. When the support bars are elastically deformed, the temporary fastening portions exit the state of being seated on the upper portions of the support bars, and thus the temporary fastening is released.
