Transmission Case Mirror Surface for Blind-Spot Assembly Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency in assembling control valve assemblies within transmission cases due to seating portions often being located at blind spots, leading to reduced work efficiency.
Innovation Solution
Incorporating a mirror surface portion within the transmission case's storage area to allow visual recognition of the seating portion, enabling precise alignment and assembly even when the seating area is not directly visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the seating portion is located inside the transmission case at a position that is not directly visible from the opening, then the transmission case structure is compact and simple, but the operator cannot visually recognize the seating portion, leading to reduced work efficiency
Solution Approach 1:
A mirror surface portion is introduced as an intermediary element within the transmission case to reflect light from the seating portion back to the operator's viewpoint. This allows the operator to visually recognize the seating portion indirectly through reflection, resolving the contradiction between compact structure and visual accessibility without requiring structural changes to the transmission case itself
2Manufacturing precision
If the seating portion is positioned in a blind spot area within the transmission case, then the transmission case maintains a simple and compact design, but the operator works in a situation where the seating portion is invisible, lowering assembly precision
Solution Approach 1:
The mirror surface portion serves as a mediating optical element that enables the operator to visually acquire information about the seating portion's position and state without changing the transmission case's compact structure. This resolves the contradiction by adding a simple reflective surface rather than redesigning the entire case structure
Solution Approach 2:
The mirror surface portion utilizes the third dimension (depth within the transmission case) to provide visual access to areas that would otherwise be invisible from the opening. By positioning the mirror at an appropriate angle and location, the operator can see around corners and into blind spots through reflected light paths

Function Achieved in This Case
This configuration enhances work efficiency by allowing operators to visually recognize and align the seating portion, preventing any decrease in assembly efficiency even when it is located at a blind spot.
Implementation Method 1
a mirror surface portion allowing an opposite portion of the assembling member facing the seating portion to be visually recognized when the assembling member is being inserted to the first opening from the opening direction

AI summary
A transmission case having a storage area inside for an assembling member, includes a first opening in the storage area; a seating portion provided in the storage area and on which the assembling member inserted from an opening direction of the first opening is to be seated; and a mirror-finished portion allowing an opposite portion of the assembling member facing the seating portion to be visually recognized when the assembling member is being inserted to the first opening from the opening direction.
