Productivity
![Stabilization of soldering operation with use of fixing jig Before improvement](/taiyo/en/common/img/activity/improvement/improvement-05-img01.jpg)
When performing the soldering operation, the act of looking into the operations area caused fatigue for the operator.
![Stabilization of soldering operation with use of fixing jig After improvement](/taiyo/en/common/img/activity/improvement/improvement-05-img02.jpg)
A fixing jig enabled alignment with the operator's line of sight position, achieving reduction of operator fatigue.
Use of jig for simplification of stamping operation
Lot number stamping operation
Quality Productivity
![Simplification of stamping operation Before improvement](/taiyo/en/common/img/activity/improvement/improvement-04-img01.jpg)
Because it is a manual operation, scattering of the stamp location occurred.
![Simplification of stamping operation After improvement](/taiyo/en/common/img/activity/improvement/improvement-04-img02.jpg)
With a fixing jig, equalization of the stamp location shortened the operation from 10 seconds per item to just 4 seconds.
Utilization of jig for simplification of parts assembly method
Shaft assembly operation
Expansion of occupational range Productivity
![Simplification of parts assembly method Before improvement](/taiyo/en/common/img/activity/improvement/improvement-03-img01.jpg)
Operation for holding down a small part with the fingers required experience, and operators were limited.
![Simplification of parts assembly method After improvement](/taiyo/en/common/img/activity/improvement/improvement-03-img02.jpg)
With a jig holding down the part, it became possible for anyone to perform the operation, with the operation shortened from 10 seconds per item to just 7-8 seconds.
Review of line for productivity improvement
Line integration
Productivity
![Construction of simplified line with multiple processes Before improvement](/taiyo/en/common/img/activity/improvement/improvement-02-img01.jpg)
The previous line positioned persons at each process.
![Construction of simplified line with multiple processes After improvement](/taiyo/en/common/img/activity/improvement/improvement-02-img02.jpg)
Multiple processes can now be performed in a single process.
Facility improvements for increased efficiency
Wiper height inspection
Expansion of occupational range Productivity
![Use of rotation method to improve business operations efficiency Before improvement](/taiyo/en/common/img/activity/improvement/improvement-01-img01.jpg)
When changing procedures, the inspection facility needed to be moved, which was a difficult operation for wheelchair operators.
![Use of rotation method to improve business operations efficiency After improvement](/taiyo/en/common/img/activity/improvement/improvement-01-img02.jpg)
The inspection facility can now be rotated, making changing procedures simple even for wheelchair operators.
Streamlining of applying bonding agent to lead wires
Applying bonding agent to lead wires of switches
Work scope enlargementQualityProductivity
![リード線へのボンド塗布作業の簡素化する改善 改善前](/taiyo/en/common/img/activity/improvement/improvement-11-img01.jpg)
This used to be a difficult work process requiring two workers with experience in bonding agent application who must operate standing.
![リード線へのボンド塗布作業の簡素化する改善 改善後](/taiyo/en/common/img/activity/improvement/improvement-11-img02.jpg)
Introduction of bonding devices streamlined the work process by achieving semi-automation. This enabled work performance by a single wheel-chaired worker and achieved work scope enlargement. Execution of the work process was enabled also through workers not pre-determined for this process.
Improvement of the stamping process
Product type and lot number are stamped, followed by the combining of the products
Work scope enlargementQuality
![捺印工程の改善 改善前](/taiyo/en/common/img/activity/improvement/improvement-12-img01.jpg)
Combining the products used to be time consuming, the adjustment of the stamping machine's rubber stamp was difficult, and the work required pre-determined personnel. (45 seconds per combining process) The stamping ink required time for drying. (2 hours drying time)
![捺印工程の改善 改善後](/taiyo/en/common/img/activity/improvement/improvement-12-img02.jpg)
By introducing laser markers and combining automation devices, the time for printing stamp adjustments and ink drying time could be saved. This has allowed workers to incorporate the pre-processing work, thus achieving work scope enlargement. Execution of the work process was enabled also through workers not predetermined for this process.
Work process improvement for wheel-chaired workers
Work comprised of caulking the pins of components A and B to the products and assembling component C
Work scope enlargementProductivity
![障がいに合わせ移動をなくした作業結合改善 改善前](/taiyo/en/common/img/activity/improvement/improvement-13-img01.jpg)
Sideway movements to execute the next work process used to be difficult for wheel-chaired workers. (5 seconds per sideway movement)
![障がいに合わせ移動をなくした作業結合改善 改善後](/taiyo/en/common/img/activity/improvement/improvement-13-img02.jpg)
The introduction of jigs that move the positions of products obviates the need for wheel-chaired workers to move.
Improvement of inspection devices by adjustments consistent with the disability
Work process of assessing product conformity using inspection devices
Work scope enlargementQuality
![障がいに合わせた検査機の改善 改善前](/taiyo/en/common/img/activity/improvement/improvement-14-img01.jpg)
A buzzer used to sound when a product was found non-conforming during an inspection. Non-conforming products were collected in designated red containers but the process was left to workers discretion.
![障がいに合わせた検査機の改善 改善後](/taiyo/en/common/img/activity/improvement/improvement-14-img02.jpg)
By additionally equipping inspection devices with rotating warning lamps, thus alerting inspection workers by sound and sight, the scope of work is enlarged to workers with a hearing disability. Causing inspection devices to stop operating if a non-conforming product is not placed into the designated red container helps prevent human error.

Work scope enlargementProductivity
![圧入組合せ作業負担軽減の改善 改善前](/taiyo/en/common/img/activity/improvement/improvement-15-img01.jpg)
Press-fitting of products used to be done manually. This required physical strength and made this heavy work. (6 seconds per item by a trained worker)
![圧入組合せ作業負担軽減の改善 改善後](/taiyo/en/common/img/activity/improvement/improvement-15-img02.jpg)
The adoption of press-fitting jigs enabled work execution also by workers not predetermined for this process and reduced the work load. (2 seconds per item).
