Solution Overview

Problem

Existing electric devices face damage to internal wiring during and after assembly due to contact with the cover part, which is not adequately protected, especially in harsh environments like transmission oil.

Innovation Solution

Incorporating a wiring guide element that supports the internal wiring at a position spaced apart from the sealing surface, preventing contact with the trough wall and ensuring the wiring is guided over the trough wall into the terminal area without touching the sealing surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cover part is assembled to cover the terminal area, then the wiring is protected from the operational environment, but the wiring may be damaged by contact with the cover part during assembly

Engineering Contradiction:
Improvewiring protectionVSAvoidmechanical damage to wiring
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A wiring guide element is introduced as an intermediary component between the cover part and the internal wiring. This guide element has a support surface that guides the wiring during assembly and a receiving portion that receives the wiring after assembly, preventing direct contact between the wiring and the cover part while ensuring proper positioning and protection of the wiring in the terminal area

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the trough section is used to receive the terminal area, then the wiring is enclosed and protected, but the wiring may still be damaged during assembly due to lack of support

Engineering Contradiction:
Improvewiring protectionVSAvoidassembly process
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The wiring guide element is pre-installed on the base part before the cover part is assembled. The guide element's support surface is positioned to provide preliminary support to the wiring during the assembly process, and the receiving portion is pre-configured to automatically receive and secure the wiring after assembly, ensuring both protection and ease of operation

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to an electric device (1), in particular a rotational or linear motion and/or position measurement device (5), such as a resolver (3), having a housing structure (7) and internal wiring (9), the housing structure (9) comprising a base part (17) having a terminal area (31) for connecting the internal wiring (9) to at least one outside electric conductor (71), and a cover part (39) having a trough section (61) into which the terminal area (31) at least partly extends, wherein the trough section (61) has at least one trough wall (63), which at least in sections abuts the base part (17) to form a sealing surface (67). Solutions of the art have the disadvantage that during and/or after assembly of the cover part (39) to the base part (17) the internal wiring (9) may be touched and/or damaged by the cover part (39). To prevent the internal wiring (9) to be touched or damaged by the cover part (39) during and/or after assembly of the electric device (1), according to the invention, the wiring (9) extends over the trough wall (63) into the trough section (61) to the terminal area (31), and the base part (17) comprises at least one wiring guide element (29) which supports the wiring (9) at a position spaced apart from the sealing surface (67) opposite the trough wall (63).
