Wire Holding Structure Non-Overlapping Housing Lid Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire holding structures are bulkier due to overlapping components, which hinders miniaturization and allows external matter intrusion.
Innovation Solution
A wire holding structure design where the housing and wire cover do not overlap, with a lid configuration that allows for a non-overlapping closure, incorporating contact ribs and fittings to prevent external intrusion, and a labyrinth structure to enhance sealing, adhering to the equation T2≤T1<T2+T3 for optimal miniaturization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wall of the cap and the wall of the holder overlap in a thickness direction, then the sealing between the cap and holder is improved, but the overall size of the wire holding structure is enlarged
Solution Approach 1:
The patent applies nesting by placing the holder inside the cap structure, where the holder is received within the cap's internal space. This nested arrangement allows the holder to be positioned such that its wall overlaps with the cap wall in the thickness direction, achieving sealing without increasing the external dimensions of the assembly. The holder is effectively nested within the cap's structural envelope.
Solution Approach 2:
The patent resolves the size-sealing contradiction by transitioning to a different dimensional arrangement. Instead of placing the holder and cap side-by-side (which would increase overall size), the holder is positioned in the thickness direction of the cap, utilizing the Z-dimension. This dimensional reorganization allows wall overlap for sealing while maintaining compact external dimensions.
2Stability of the object's composition
If the wire cover and housing are designed to overlap, then structural stability is improved, but miniaturization is hindered
Solution Approach 1:
The housing is nested within the wire cover structure, with the wire cover forming an outer envelope that receives the housing. This nesting allows the components to be arranged in a space-efficient manner, achieving structural stability through proper positioning and engagement features while minimizing the overall external dimensions of the assembly.
3Ease of manufacture
If the opening of the wire cover is left open, then ease of assembly is improved, but intrusion of external matter occurs
Solution Approach 1:
The sealing function is segmented from the main housing structure and assigned to a separate lid component. The lid can be assembled independently into the wire cover opening, providing sealing without complicating the main assembly process. This segmentation allows the opening to remain accessible during assembly while still enabling effective sealing when the lid is in place.
Solution Approach 2:
The lid acts as an intermediary element between the wire cover opening and the internal components. It provides the sealing function that prevents external matter intrusion while maintaining the simplicity of the overall assembly process. The lid mediates between the need for an open assembly structure and the requirement for sealed protection.
